xref #6249, #18262, #35301
Following up on #35301. This is an outstanding piece of `DataFrame.xs` functionality that's currently not available in `.loc`. Since `xs` is slated for deprecation I'd like implement this in `.loc`
#### Example
Let's define a multiindexed dataframe (example from `xs` docs)
```
...: import pandas as pd
...:
...: d = {
...: 'num_legs': [4, 4, 2, 2],
...: 'num_wings': [0, 0, 2, 2],
...: 'class': ['mammal', 'mammal', 'mammal', 'bird'],
...: 'animal': ['cat', 'dog', 'bat', 'penguin'],
...: 'locomotion': ['walks', 'walks', 'flies', 'walks']
...: }
...:
...: df = pd.DataFrame(data=d)
...: df.set_index(['class', 'animal', 'locomotion'], inplace=True)
In [2]: df
Out[2]:
num_legs num_wings
class animal locomotion
mammal cat walks 4 0
dog walks 4 0
bat flies 2 2
bird penguin walks 2 2
```
`xs` and `.loc` both let us take a cross-section through a `MultiIndex`
```
In [3]: import pandas._testing as tm
...:
...: res_xs = df.xs(('mammal', slice(None)))
...: res_loc = df.loc[('mammal', slice(None))]
...: tm.assert_frame_equal(res_xs, res_loc)
```
but with `xs` we can choose to keep the index columns through which we're slicing using the `drop_level` argument:
```
In [4]: df.xs(('mammal', slice(None), 'flies'), drop_level=False)
Out[4]:
num_legs num_wings
class animal locomotion
mammal bat flies 2 2
```
#### new API
Looking for ideas on what's appropriate here. Based off of suggestions in #6249 would something like this work?
```
In [ ]: df.loc(drop_levels=False)[('mammal', slice(None), 'flies')]
Out[4]:
num_legs num_wings
class animal locomotion
mammal bat flies 2 2
```

#### Location of the documentation
https://pandas.pydata.org/docs/user_guide/io.html#external-compatibility.
#### Documentation problem
This section probably has at least one typo, but more generally, doesn't seem to be documenting current behaviour.
I'll quickly run through the example here, but with a bit of cleaning so we don't have to run the entire page.
```python
import pandas as pd
import numpy as np
df_for_r = pd.DataFrame({"first": np.random.rand(100),
"second": np.random.rand(100),
"class": np.random.randint(0, 2, (100, ))},
index=range(100))
store_export = pd.HDFStore('export.h5')
# In the documentation, this is written with 'data_columns=df_dc.columns', which I'm assuming is a mistake
store_export.append('df_for_r', df_for_r, data_columns=df_for_r.columns)
store_export
```
We can take a look at what's in this file:
```python
store_export.close()
!h5ls -r export.h5
```

Next, there is an R function for reading in this data. Just from comparing the given function to the written file I think we can see there is a mismatch:
```R
library(rhdf5)
loadhdf5data <- function(h5File) {
listing <- h5ls(h5File)
# Find all data nodes, values are stored in *_values and corresponding column
# titles in *_items
data_nodes <- grep("_values", listing$name)
name_nodes <- grep("_items", listing$name)
data_paths = paste(listing$group[data_nodes], listing$name[data_nodes], sep = "/")
name_paths = paste(listing$group[name_nodes], listing$name[name_nodes], sep = "/")
columns = list()
for (idx in seq(data_paths)) {
# NOTE: matrices returned by h5read have to be transposed to obtain
# required Fortran order!
data <- data.frame(t(h5read(h5File, data_paths[idx])))
names <- t(h5read(h5File, name_paths[idx]))
entry <- data.frame(data)
colnames(entry) <- names
columns <- append(columns, entry)
}
data <- data.frame(columns)
return(data)
}
```
For example, there are no entries in `export.h5` which have `_values` or `_items` in the names.
If we actually call this function, we get an empty dataframe back:
```R
> loadhdf5data("export.h5")
data frame with 0 columns and 0 rows
```
This function does seem to work if the file is written using "fixed" format
```python
df_for_r.to_hdf("export2.h5", key="df_for_r", format="fixed")
```
```R
> loadhdf5data("export2.h5")
first second class
1 0.675013759 0.787289926 0
2 0.936797348 0.349671699 1
3 0.951930811 0.275965069 0
4 0.203085530 0.380154180 0
5 0.627195223 0.462702969 1
6 0.129148756 0.385663581 1
...
```
This is a bit contrary to the prose for this section which reads:
> HDFStore writes table format objects in specific formats suitable for producing loss-less round trips to pandas objects. For external compatibility, HDFStore can read native PyTables format tables.
>
> It is possible to write an HDFStore object that can easily be imported into R using the rhdf5 library (Package website). Create a table format store like this:
#### Suggested fix for documentation
This should probably specify that the "table" format doesn't work here. In addition, since external compatibility relies on the user writing code to read this format, maybe a specification for the format should be documented here?

Serializing a data frame with an interval index to JSON and then deserializing it fails to recover the index. Here is an example:
```
df = pd.DataFrame(index=pd.IntervalIndex(closed='left', dtype='interval[int64]',
data=[pd.Interval(0, 2, closed='left')]),
data={'a': [42'})
serialized = df.to_json(orient='table')
deserialized = pd.read_json(serialized, orient='table')
```
Looking at `serialized` reveals that the interval index is serialized as `any` type looking like that:
```
{"closed":"left","closed_right":false,"left":0,"mid":0.5,"open_right":true,"right":1}
```
and looking at `deserialized.index[0]` reveals that the interval type wasn't recovered but rather the de-serialized value is still a dict:
```
{'closed': 'left',
'closed_right': False,
'left': 0,
'mid': 1.0,
'open_right': True,
'right': 2}
```

Would be cool if pandas supported reading YAML files.
#### Describe the solution you'd like
`pd.read_yaml(file_path: str, **kwargs: dict)`
#### API breaking implications
None
#### Describe alternatives you've considered
You can of course import the `yaml` module, use it to read the file and then feed that data into pandas.
```py
import pandas as pd
import yaml
with open("data.yml") as stream:
data = yaml.safe_load(stream)
df = pd.DataFrame(data)
```
But for a format that has become as widely used as YAML, this is a lot of manual work compared to
```py
import pandas as pd
df = pd.read_yaml("data.yml")
```

It seems that a data frame with an `IntervalIndex` won't let you use `loc[]` or `at[]` to add rows.
I would expect the following to work:
```
df = pd.DataFrame(index=pd.IntervalIndex(closed='left', dtype='interval[int64]',
data=[pd.Interval(0, 1, closed='left')]),
data={'a': [42]})
df.at[pd.Interval(2, 3, closed='left'), 'a'] = 43
```
However, it throws a confusing error
```
AttributeError: 'pandas._libs.interval.IntervalTree' object has no attribute 'set_value'
```

- [x] I have checked that this issue has not already been reported.
- [x] I have confirmed this bug exists on the latest version of pandas.
- [x] (optional) I have confirmed this bug exists on the master branch of pandas.
---
While working on #35314 I made a change that broke `GroupBy.apply` if you called it on a DataFrame with duplicate columns; however, this break as not caught by any test. Was just caught on inpsection: https://github.com/pandas-dev/pandas/pull/35314#discussion_r460000612
This issue is just to add a test for this case to ensure it works and doesn't break again in the future.

While working on #35314 I made a change that broke `GroupBy.apply` if you called it on a DataFrame with duplicate columns; however, this break was not caught by any test. Was just caught on inpsection: https://github.com/pandas-dev/pandas/pull/35314#discussion_r460000612
This PR is just to add a test for this case to ensure it works and doesn't break again in the future.

- [x] I have checked that this issue has not already been reported.
- Has sort of come up in other issues related to metadata/attrs not propagating through properly, however I haven't seen any issues specifically about `Series` attrs being lost when put into a `DataFrame`.
- [x] I have confirmed this bug exists on the latest version of pandas.
- [x] (optional) I have confirmed this bug exists on the master branch of pandas.
---
**Note**: Please read [this guide](https://matthewrocklin.com/blog/work/2018/02/28/minimal-bug-reports) detailing how to provide the necessary information for us to reproduce your bug.
#### Code Sample, a copy-pastable example
See this [GitHub Gist Notebook](https://gist.github.com/RobertRosca/d3c53151dd93242c448daf008fb4bb23).
Summary of the issue is:
```python
import pandas as pd
# Make some dummy dataframe
df = pd.DataFrame({'col1': [1, 2], 'col2': [3, 4]})
# Make some dummy series
col1_w_attr = df["col1"].copy()
# Add some attrs to it
col1_w_attr.attrs["test_attr"] = 1
df["col1_w_attr"] = col1_w_attr
# Issue 1: The attrs are missing, call `__finalize__` manually
df["col1_w_attr"].__finalize__(col1_w_attr)
# Repeat the above with another column:
col2_w_attr = df["col2"].copy()
col2_w_attr.attrs["test_attr"] = 2
df["col2_w_attr"] = col2_w_attr
df["col2_w_attr"].__finalize__(col2_w_attr)
# Attrs are present as before
df["col2_w_attr"].attrs
# Issue 2: col1_w_attrs is now missing its attrs:
df["col1_w_attr"].attrs
```
#### Problem description
First issue is that attrs are not propagated through when a `Series` is added to a `DataFrame` (likely related to #28283).
Second issue is that if you call `__finalize__` to make sure that the attrs are present, once you add another column in or modify the dataframe, the attrs already present for a column are lost. My guess is that when the DataFrame is modified, finalize is not called per-column again, but I haven't looked into it much.
I'd be happy to help with this issue, however there are already many issues related to this topic and a few branches where others are working on attrs/metadata/finalize, so I'm a bit hesitant to start work as it'll probably conflict with what has already been done.
What would be the best place to discuss collaboration on this?
#### Expected Output
Expectation would be that you can attach some attrs to a Series, place it into a dataframe, modify/work with the dataframe, then access the attrs again.

#### Problem description
Looks like a change in numpy broke our `read_stata` code, so now we have a bunch of `read_stata` test errors popping up during CI in the numpy_dev pipeline. Maybe this [Numpy PR](https://github.com/numpy/numpy/pull/16943) somehow broke things? I don't think any other PR merged during the last 24 hours could have possibly done so, although I might be missing something.
Error example:
```
pandas/tests/io/test_stata.py:52:
_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _
pandas/io/stata.py:1928: in read_stata
data = reader.read()
pandas/io/stata.py:1646: in read
cols_ = np.where(self.dtyplist)[0]
_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _
args = ([<class 'numpy.int8'>, <class 'numpy.int16'>, <class 'numpy.int32'>, <class 'numpy.float32'>, <class 'numpy.float64'>, <class 'numpy.float32'>, ...],)
kwargs = {}
relevant_args = ([<class 'numpy.int8'>, <class 'numpy.int16'>, <class 'numpy.int32'>, <class 'numpy.float32'>, <class 'numpy.float64'>, <class 'numpy.float32'>, ...], None, None)

This PR is an attempt to address concerns about datetime parsing. I'll update the docs if people approve this change.
#### Original problem
From #12585:
``` python
In [3]: pd.to_datetime(["31/12/2014", "10/03/2011"])
...:
Out[3]: DatetimeIndex(['2014-12-31', '2011-03-10'], dtype='datetime64[ns]', freq=None)
```
The issue is that the first item is parsed as `DD\MM\YYYY` whereas for the second the format is `MM\DD\YYYY`, and there is no message to alert the user of inconsistency in the output.
The problem lies with the `dayfirst` argument that selects between `DD\MM\YYYY` and `MM\DD\YYYY`. In the parser:
https://github.com/pandas-dev/pandas/blob/04e9e0afd476b1b8bed930e47bf60ee20fa78f38/pandas/_libs/tslibs/parsing.pyx#L94-L163
we try `DD\MM\YYYY` or `MM\DD\YYYY` first depending on `dayfirst` but if the result is invalid we try the other.
#### Proposed change
I'd like to raise warnings whenever we parse in contradiction to the directive of `dayfirst`. The OP, where `dayfirst` defaults to `False`, now raises a Warning:
``` python
In [4]: pd.to_datetime(["31/12/2014", "10/03/2011"], dayfirst=False)
...:
/workspaces/pandas-arw2019/pandas/core/arrays/datetimes.py:2044: UserWarning: Parsing 31/12/2014 DD/MM format.
result, tz_parsed = tslib.array_to_datetime(
Out[4]: DatetimeIndex(['2014-12-31', '2011-10-03'], dtype='datetime64[ns]', freq=None)
```
A downside of this change is that sometimes a consistent output produces unnecessary warnings (due to mismatch with the default value of `dayfirst`):
``` python
In [11]: pd.to_datetime(["31/12/2014", "30/04/2011", "31/05/2016"] )
/workspaces/pandas-arw2019/pandas/core/arrays/datetimes.py:2044: UserWarning: Parsing 31/12/2014 DD/MM format.
result, tz_parsed = tslib.array_to_datetime(
/workspaces/pandas-arw2019/pandas/core/arrays/datetimes.py:2044: UserWarning: Parsing 30/04/2011 DD/MM format.
result, tz_parsed = tslib.array_to_datetime(
/workspaces/pandas-arw2019/pandas/core/arrays/datetimes.py:2044: UserWarning: Parsing 31/05/2016 DD/MM format.
result, tz_parsed = tslib.array_to_datetime(
Out[11]: DatetimeIndex(['2014-12-31', '2011-04-30', '2016-05-31'], dtype='datetime64[ns]', freq=None)
```
but these can be silenced with `infer_datetime_format`:
``` python
In [12]: pd.to_datetime(["31/12/2014", "30/04/2011", "31/05/2016"], infer_datetime_format=True )
Out[12]: DatetimeIndex(['2014-12-31', '2011-04-30', '2016-05-31'], dtype='datetime64[ns]', freq=None)
```
For invalid input (if it cannot be parsed according to a single format) we will *always* raise a warning, even with `infer_datetime_format=True`:
``` python
In [13]: pd.to_datetime(["31/12/2014", "03/31/2011"], infer_datetime_format=True)
/workspaces/pandas-arw2019/pandas/core/arrays/datetimes.py:2044: UserWarning: Parsing 31/12/2014 DD/MM format.
result, tz_parsed = tslib.array_to_datetime(
Out[13]: DatetimeIndex(['2014-12-31', '2011-03-31'], dtype='datetime64[ns]', freq=None)
```
#### Remaining issues
Personally I can see a case for raising an error with
``` python
In [13]: pd.to_datetime(["31/12/2014", "03/31/2011"], infer_datetime_format=True)
```
since there's no valid way to process that. I also think that
``` python
In [11]: pd.to_datetime(["31/12/2014", "30/04/2011", "31/05/2016"])
```
shouldn't be raising warnings, but I feel much less strongly about that. That said, changing this behaviour will require more heavy-handed alterations to the codebase (and maybe performance implications - not sure).
I think that the warnings I added here will allow users to figure out the origin of these problems when they turn up and that should do away with most of the headaches.

---
**Note**: Please read [this guide](https://matthewrocklin.com/blog/work/2018/02/28/minimal-bug-reports) detailing how to provide the necessary information for us to reproduce your bug.
#### Code Sample, a copy-pastable example
```python
>>> a = pd.DataFrame([{'col': 'a'}] * 3).convert_dtypes()
>>> a
col
0 a
1 a
2 a
>>> tfna = pd.Series([True, False, pd.NA]).convert_dtypes()
>>> tfna
0 True
1 False
2 <NA>
dtype: boolean
>>> a.mask(tfna, 'b')
col
0 b
1 a
2 b
>>> a.where(tfna, 'b')
col
0 a
1 b
2 b
```
#### Problem description
When replacing values with `mask` or `where`, `pd.NA` values in a boolean series used for the `cond` input are always replaced. This means `pd.NA` gets treated as `False` by `where` but as `True` by `mask`.
#### Expected Output
I would expect that `pd.NA` values in `cond` would propagate to the output.
```python
>>> a.mask(tfna, 'b')
col
0 b
1 a
2 <NA>
>>> a.where(tfna, 'b')
col
0 a
1 b
2 <NA>
```

If `timestamp.csv` contains the following:
```
timestamp
11:22:33.44
11:22:33:44
```
then
```python
df = pandas.read_csv('timestamp.csv', parse_dates=['timestamp'])
df.timestamp.dtype
```
results in
```
dtype('O')
```
because of the malformed timestamp.
#### Problem description
This is a problem because the silent fail does not alert to the malformed timestamp.
#### Expected Output
By contrast,
```python
pandas.to_datetime(df.timestamp)
```
results in an explicit error
```python
ParserError: Unknown string format: 11:22:33:44
```

If `index.csv` contains:
```
id,key
00,11
22,33
```
then
```python
df = pandas.read_csv('index.csv', dtype=str, index_col='id')
df.index.dtype
```
results in
```
dtype('int64')
```
#### Problem description
This does not result in an index of strings.
#### Expected Output
By contrast,
```python
df = pandas.read_csv('index.csv', dtype=str)
df.set_index('id', inplace=True)
df.index.dtype
```
results in
```
dtype('O')
```
as intended.

The ``._cached_data`` attribute is not necessary. It was originally added to allow a check to see if the ``._data`` ndarray had been created, but that's also possible to do by a ``"_data" in _cache`` check in the new implemention, which IMO would be more idiomatic.
The new implementation has the benefit that the ``_data`` will be available to new copies of a RangeIndex, saving the need to create a new ndarray for each new copy of the RangeIndex.
```python
>>> idx = pd.RangeIndex(1_000_000)
>>> idx[[1, 4]] # this accesses ._data and saves it in cached_data (master) or _cache["_data"](this PR)
>> %timeit idx._shallow_copy()[[1, 4]]
2.55 ms ± 69.3 µs per loop # master
17.7 µs ± 405 ns per loop # this PR
```

---
**Note**: Please read [this guide](https://matthewrocklin.com/blog/work/2018/02/28/minimal-bug-reports) detailing how to provide the necessary information for us to reproduce your bug.
#### Code Sample, a copy-pastable example
```python
import pandas as pd
test = pd.DataFrame([
[1, {'c': 1}],
[2, {'c': 2}],
[3, {'c': 3}],
[4, {'c': 4}],
[5, {'c': 5}]
], columns=['A', 'B'])
print(test[['A', 'B']].apply(lambda x: x.nlargest(2, keep='all') if x.name in ['A'] else x.apply(lambda y: y['c']).nsmallest(2, keep='all')))
```
#### Problem description
On and after Python version 3.6.1, the above code crashes with the error: `TypeError: Cannot use method 'nlargest' with dtype object`. This happens because the `apply(lambda x` function is applying to both columns, even though the `if/else` check should only apply it to the specified column. I am not certain if this is a bug in Python itself, or if python changed and Pandas needs to update to match. I am starting here, though, because I believe the issue will be identified (and fixed if necessary) quicker. On previous versions, the following output is produced:
#### Expected Output
```
>>> test[['A', 'B']].apply(lambda x: x.nlargest(2, keep='all') if x.name in ['A'] else x.apply(lambda y: y['c']).nsmallest(2, keep='all'))
A B
0 NaN 1.0
1 NaN 2.0
3 4.0 NaN
4 5.0 NaN
```

#### Code Sample, a copy-pastable example
```python
import pandas as pd
import numpy as np

#### Code Sample, a copy-pastable example
```python
import pandas as pd
df = pd.DataFrame([], columns=["s"]).astype({"s": "string"})
df.to_parquet("out.parquet")
df2 = pd.read_parquet("out.parquet") # <- Exception thrown here
```
```python-traceback
Traceback (most recent call last):
File "<input>", line 1, in <module>
df2 = pd.read_parquet("out.parquet")
File "/usr/local/lib/python3.8/site-packages/pandas/io/parquet.py", line 312, in read_parquet
return impl.read(path, columns=columns, **kwargs)
File "/usr/local/lib/python3.8/site-packages/pandas/io/parquet.py", line 126, in read
result = self.api.parquet.read_table(
File "pyarrow/array.pxi", line 715, in pyarrow.lib._PandasConvertible.to_pandas
File "pyarrow/table.pxi", line 1565, in pyarrow.lib.Table._to_pandas
File "/usr/local/lib/python3.8/site-packages/pyarrow/pandas_compat.py", line 779, in table_to_blockmanager
blocks = _table_to_blocks(options, table, categories, ext_columns_dtypes)
File "/usr/local/lib/python3.8/site-packages/pyarrow/pandas_compat.py", line 1116, in _table_to_blocks
return [_reconstruct_block(item, columns, extension_columns)

pd_ext_arr = pandas_dtype.__from_arrow__(arr)

return StringArray._concat_same_type(results)
File "/usr/local/lib/python3.8/site-packages/pandas/core/arrays/numpy_.py", line 171, in _concat_same_type
return cls(np.concatenate(to_concat))
File "<__array_function__ internals>", line 5, in concatenate
ValueError: need at least one array to concatenate
```
#### Problem description
All of the code is produced with pyarrow. fastparquet is not affected by this bug as it does not support pandas extension type
(See: https://github.com/dask/fastparquet/issues/465).
This problem only occurs when the row number is 0 and contains pandas extension type (`Int64`, `string`, etc).
It does not happen when there is 1 row. Even if the row contains `pd.NA`. For example, following code works:
```python
import pandas as pd
df = pd.DataFrame([{"s": pd.NA}], columns=["s"]).astype({"s": "Int64"})
df.to_parquet("out.parquet")
pd.read_parquet("out.parquet")
```
The above code will restore the DataFrame correctly.
The problem does not occur when the column type is normal type. For example, following code works when the `dtype` is `int64`
```python
import pandas as pd
df = pd.DataFrame([], columns=["s"]).astype({"s": "int"})
df.to_parquet("out.parquet")
pd.read_parquet("out.parquet")
```
When using the pyarrow library to read the parse the output parquet, `.read_table` would fail when converting to pandas DataFrame with similar errors from `pd.read_parquet`. This only occurs on stable. Correct result is produced on environment 1 and environment 2 (See bottom for environment descriptions)
```python
import pandas as pd
import pyarrow.parquet as pq
df = pd.DataFrame([], columns=["s"]).astype({"s": "int"})
df.to_parquet("out.parquet")
table = pq.read_table("out.parquet")
table.to_pandas() # Exception here on stable. Correct result on env 1 and 2
```
```python-traceback
Traceback (most recent call last):
File "<input>", line 1, in <module>
table.to_pandas()
File "pyarrow/array.pxi", line 715, in pyarrow.lib._PandasConvertible.to_pandas
File "pyarrow/table.pxi", line 1565, in pyarrow.lib.Table._to_pandas
File "/usr/local/lib/python3.8/site-packages/pyarrow/pandas_compat.py", line 779, in table_to_blockmanager
blocks = _table_to_blocks(options, table, categories, ext_columns_dtypes)
File "/usr/local/lib/python3.8/site-packages/pyarrow/pandas_compat.py", line 1116, in _table_to_blocks
return [_reconstruct_block(item, columns, extension_columns)
File "/usr/local/lib/python3.8/site-packages/pyarrow/pandas_compat.py", line 1116, in <listcomp>
return [_reconstruct_block(item, columns, extension_columns)
File "/usr/local/lib/python3.8/site-packages/pyarrow/pandas_compat.py", line 738, in _reconstruct_block
pd_ext_arr = pandas_dtype.__from_arrow__(arr)
File "/usr/local/lib/python3.8/site-packages/pandas/core/arrays/integer.py", line 113, in __from_arrow__
return IntegerArray._concat_same_type(results)
File "/usr/local/lib/python3.8/site-packages/pandas/core/arrays/masked.py", line 175, in _concat_same_type
data = np.concatenate([x._data for x in to_concat])
File "<__array_function__ internals>", line 5, in concatenate
ValueError: need at least one array to concatenate
```
However, reading the dataframe with `.read_pandas` would succeed with expected result in all environments.
```python
import pandas as pd
import pyarrow.parquet as pq
df = pd.DataFrame([], columns=["s"]).astype({"s": "int"})
df.to_parquet("out.parquet")
table = pq.read_pandas("out.parquet")
df2 = table.to_pandas() # No exception here
df.equals(df2) # Retruns True
```
The produced DataFrame is as expected with correct column type. This could be used as a workround for now.
#### Expected Output
The parquet should be read successfuly.
#### Output of ``pd.show_versions()``
(The code is run under docker image `python:3.8-slim`)
##### Stable environment
All packages installed from pip directly

#### Location of the documentation
User guide ['Intro to data structures'](https://pandas.pydata.org/docs/dev/user_guide/dsintro.html#dataframe)
(alternatively [`DataFrame` API docs](https://pandas.pydata.org/docs/dev/reference/api/pandas.DataFrame.html?highlight=dataframe#pandas.DataFrame))
#### Documentation problem
I recently only found out through a [StackOverflow answer](https://stackoverflow.com/a/51173794/) that the `DataFrame` constructor can take a list of namedtuples and automatically infers column names from it. Until then I had only found the [`DataFrame.from_records`](https://pandas.pydata.org/docs/dev/reference/api/pandas.DataFrame.from_records.html#pandas.DataFrame.from_records) constructor, which manually requires specifying `columns=Namedtuple._fields`.
After searching the documentation for [namedtuple](https://pandas.pydata.org/docs/dev/search.html?q=namedtuple), I haven't been able to find an explicit mention of constructors accepting namedtuples, while there is apparently explicit code in the constructor to deal with them nicely. Currently it only finds mentions where internal functions return rows as namedtuples.
In contrast, searching for e.g. ['dataclass'](https://pandas.pydata.org/docs/dev/search.html?q=dataclass) finds [an explicit paragraph](https://pandas.pydata.org/docs/dev/user_guide/dsintro.html?highlight=dataclass#from-a-list-of-dataclasses) listing the option.
#### Suggested fix for documentation
I would propose adding an explicit mention and/or example somewhere that these kinds of inputs are accepted/encouraged, such that they can be easily found when searching for the 'namedtuple' keyword.
I can write a similar paragraph as for dataclasses in the intro to data structures, if that is indeed the right place for this.

The output of ``df.to_string`` is different if the columns is a ``CategoricalIndex`` rather than a normal ``Index``:
```python
>>> data = [[4, 2], [3, 2], [4, 3]]
>>> cols = ["aaaaaaaaa", "b"]
>>> pd.DataFrame(data, columns=cols)
aaaaaaaaa b
0 4 2
1 3 2
2 4 3
>>> pd.DataFrame(data, columns=pd.CategoricalIndex(cols))
aaaaaaaaa b
0 4 2
1 3 2
2 4 3
```
We can see that the width of the "b" column depends on the width of the "a" column, if the columns are a ``CategoricalIndex``.
These two examples should return the same repr.

*Behavioural Change*
`GroupBy.apply` would sometimes throw an erroneous `ValueError: cannot reindex from duplicate axis` because when it checked if the output was mutated from its original shape it would only check the index, when sometimes it should check the columns.
*Tests*
One new test added on `test_apply.py` which fails on master because of the bug; passes with this PR. One existing test was marked *xfail* but the *xfail* is now removed. One existing test previously had to manipulate the expected index, but that is no longer necessary.
All of the copy-pasteable examples from #16646 are fixed with this PR.

```python
import pandas as pd
df = pd.DataFrame(['Test', '123'])
'test' in df[0]
> False
```
I am not sure if this made on purpose, but I think this should return True. False seems a bit strange. Is there a good reason for this?

xref #9959
When subsetting the columns of a dataframe after a groupby to a series:
df = pd.DataFrame({'a': [1], 'b': [2], 'c': [3]}).set_index('a')
g = df.groupby('a')['b']
the public-facing groupby arguments `axis` and `as_index` are not passed on to the resulting `SeriesGroupBy`.
I think the following two examples should probably behave the same:
g = df.groupby('a', as_index=False)['b']
g2 = df['b'].groupby('a', as_index=False)
but the first produces
````
b
0 2
````
And the 2nd deliberately raises `TypeError: as_index=False only valid with DataFrame`.
Note that the arguments `axis` and `as_index` are only meant for DataFrames, and as such, I think a line such as
g = df.groupby('a', as_index=False)['b']
should raise.

Avoiding the behavior of Series here, e.g. `df.groupby('a')['b']` as I think that will involve some API changes. Will follow up: ref #35443

- Can only operate on numeric data and will return float64

- [x] I have checked that this issue has not already been reported.
- [x] I have confirmed this bug exists on the latest version of pandas.
- [ ] (optional) I have confirmed this bug exists on the master branch of pandas.
---
**Note**: Please read [this guide](https://matthewrocklin.com/blog/work/2018/02/28/minimal-bug-reports) detailing how to provide the necessary information for us to reproduce your bug.
#### Code Sample, a copy-pastable example
```python
import pandas as pd
a = pd.DataFrame({"a": list("bc"), "b": [1, 2]})
pd.testing.assert_frame_equal(a, a.copy(), check_exact=True)
```
```pytb
...: a = pd.DataFrame({"a": list("bc"), "b": [1, 2]})
...: pd.testing.assert_frame_equal(a, a.copy(), check_exact=True)
---------------------------------------------------------------------------
AssertionError Traceback (most recent call last)
<ipython-input-2-bac78c400991> in <module>
1 import pandas as pd
2 a = pd.DataFrame({"a": list("bc"), "b": [1, 2]})
----> 3 pd.testing.assert_frame_equal(a, a.copy(), check_exact=True)
[... skipping hidden 2 frame]
AssertionError: check_exact may only be used with numeric Series
```
#### Problem description
Previously, the example above would not have thrown an error. It makes it a less useful function if I have to start subdividing dataframes by types just to check that they are equal. Presumably check_exact should either have no effect if called on a non-numeric `Series` or `assert_frame_equal` should not pass `check_exact=True` if the series to be compared isn't numeric.
It looks like this was introduced recently, in https://github.com/pandas-dev/pandas/commit/08c65973643b73e877133d1a7391de7092f4b267
#### Expected Output
I expected it to work like it did previously, and not throw an error. [Here's an example of test failures this is causing](https://travis-ci.org/github/theislab/anndata/jobs/712782637).

Added the documentation for what happens if chunksize is left as None.
Is there a good way to make this DRY somehow?

#### Code Sample:
```python
import pandas as pd
df = pd.DataFrame({"date": ["2019-02-10", "2019-02-10", "2019-02-11"]})
df["date"] = pd.to_datetime(df["date"])
print("Type before the for cycle:")
print(type(df["date"][0])) # pandas._libs.tslibs.timestamps.Timestamp
for day in df["date"].unique():
print("Type in the loop:")
print(type(day)) # here is a numpy.datetime64
```
which returns:
```
Type before the for cycle:
<class 'pandas._libs.tslibs.timestamps.Timestamp'>
Type in the loop:
<class 'numpy.datetime64'>
Type in the loop:
<class 'numpy.datetime64'>
```
#### Problem description
The function `unique()` should not cast the data type.
#### Expected Output
types of `df_target["date"].unique()` should be the same as in ` set(df_target["date"].to_list())`. E.g.
```python
import pandas as pd
df = pd.DataFrame({"date": ["2019-02-10", "2019-02-10", "2019-02-11"]})
df["date"] = pd.to_datetime(df["date"])
print("Type before the for cycle:")
print(type(df["date"][0]))
for day in set(df["date"].to_list()):
print("Type in the loop:")
print(type(day))
```
Returning:
```
Type before the for cycle:
<class 'pandas._libs.tslibs.timestamps.Timestamp'>
Type in the loop:
<class 'pandas._libs.tslibs.timestamps.Timestamp'>
Type in the loop:
<class 'pandas._libs.tslibs.timestamps.Timestamp'>
```

#### Code Sample
```python
import pandas as pd
df = pd.DataFrame({"date": ["2019-02-10", "2019-02-11"]})
df["date"] = pd.to_datetime(df["date"])
print("Date Types in column date:")
for day in df["date"]:
print(type(day)) # pandas._libs.tslibs.timestamps.Timestamp
print("Unique date Types in column date:")
for day in df["date"].unique():
print(type(day)) # np.datetime64
```
The code above results in:
```
Date Types in column date:
<class 'pandas._libs.tslibs.timestamps.Timestamp'>
<class 'pandas._libs.tslibs.timestamps.Timestamp'>
Unique date Types in column date:
<class 'numpy.datetime64'>
<class 'numpy.datetime64'>
```
#### Problem description
The class method `unique()` should not change the type of the elements in the original column.
#### Expected Output
```
Date Types in column date:
<class 'pandas._libs.tslibs.timestamps.Timestamp'>
<class 'pandas._libs.tslibs.timestamps.Timestamp'>
Unique date Types in column date:
<class 'pandas._libs.tslibs.timestamps.Timestamp'>

- [ ] I have checked that this issue has not already been reported.
- [ ] I have confirmed this bug exists on the latest version of pandas.
- [x] (optional) I have confirmed this bug exists on the master branch of pandas.
---
**Note**: Please read [this guide](https://matthewrocklin.com/blog/work/2018/02/28/minimal-bug-reports) detailing how to provide the necessary information for us to reproduce your bug.
#### Code Sample, a copy-pastable example
```python
import pandas as pd
import numpy as np
df1 = pd.DataFrame(data = {"A" : [np.nan, 1], "B": [np.nan, 2], "C": [np.nan, np.nan]})
df2 = pd.DataFrame(data = [[np.nan, 1],
[np.nan, 2],
[np.nan, np.nan]],
columns = ["A", "B"])
# dataframe created with mixed values of bool and numeric with shape - 4,4
df3 = pd.DataFrame(data = [[1, np.nan, np.nan, True],
[np.nan, 2, np.nan, True],
[np.nan, np.nan, np.nan, False],
[np.nan, np.nan, np.nan, np.nan]],
columns = ["col1", "col2", "col3", "col4"])
```
#### Problem description
The [documentation](https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.any.html) for any() method states that for empty row/column, **np.nan is treated as True**. So if the parameter "skipna = False", then the empty row should result in True for either, axis = 0/ index or 1/columns.
The dataframe.any(skipna = False, axis = {1 or 0}) method works as documented for df1 and df2. However, it behaves differently for df3.
(Similar output is obtained for df1 as well hence not included here) The obtained output for df2 is like this:
```
# df2.any(axis = 1, skipna = False) # df2.any(axis = "columns", skipna = False)
0 True
1 True
2 True
dtype: bool
# df2.any(axis = 0, skipna = False) # df2.any(axis = "index", skipna = False)
A True
B True
dtype: bool
```
The obtained output for df3 is like this:
```
# df3.any(axis = 1, skipna = False) # df3.any(axis = "columns", skipna = False)
0 1
1 NaN
2 NaN
3 NaN
dtype: object
# df3.any(axis = 0, skipna = False) # df3.any(axis = "index", skipna = False)
col1 1
col2 NaN
col3 NaN
col4 True
dtype: object
```
#### Expected Output
```
# The expected output for df3 should be, similar to df2's output, and like this:
# df3.any(axis = 1, skipna = False) # df3.any(axis = "columns", skipna = False)
0 True
1 True
2 True
3 True
dtype: object
# df3.any(axis = 0, skipna = False) # df3.any(axis = "index", skipna = False)
Col1 True
Col2 True
Col3 True
Col4 True
dtype: object
```

I am not sure where exactly I am going wrong with df3. I also thought of appending this issue with the open issue related to "bool_only" parameter [here](https://github.com/pandas-dev/pandas/issues/32432). But then before reporting this confusion/error I tried the dataframe.any()method on df1 and df2, without using parameter "bool_only" and it gives the correct result. However, it again behaves very differently for df3.
Since I might have already crossed, the threshold of a minimal bug report, my experiments with the bool_only parameter are in the attached "Any_Experiments.ipynb" file.
[Any_Experiments.zip](https://github.com/pandas-dev/pandas/files/4994395/Any_Experiments.zip)
This is my first issue/ bug/ query to Pandas. Apologies for typos and/or any violations of reporting guidelines.

- [x ] I have checked that this issue has not already been reported.
- [x ] I have confirmed this bug exists on the latest version of pandas.
- [ ] (optional) I have confirmed this bug exists on the master branch of pandas.
---
**Note**: Please read [this guide](https://matthewrocklin.com/blog/work/2018/02/28/minimal-bug-reports) detailing how to provide the necessary information for us to reproduce your bug.
#### Code Sample, a copy-pastable example
```python
import pandas as pd
df = pd.DataFrame(data=[[pd.Timestamp('2011-07-03 00:00:00'), 6628480.0]])
print(df.to_numpy(dtype=str))
```
#### Problem description
I try to convert the DataFrame to a Numpy array with dtype equal to str and I got the next error.
```python-traceback
Traceback (most recent call last):
File "/main.py", line 4, in <module>
df.to_numpy(dtype=str)
File "/venv/lib/python3.7/site-packages/pandas/core/frame.py", line 1371, in to_numpy
transpose=self._AXIS_REVERSED, dtype=dtype, copy=copy, na_value=na_value
File "/venv/lib/python3.7/site-packages/pandas/core/internals/managers.py", line 826, in as_array
arr = self._interleave(dtype=dtype, na_value=na_value)
File "/venv/lib/python3.7/site-packages/pandas/core/internals/managers.py", line 864, in _interleave
result[rl.indexer] = arr
RuntimeError: The string provided for NumPy ISO datetime formatting was too short, with length 1
```
#### Expected Output
```python
[['2011-07-03 00:00:00' '6628480.0']]
```
#### Output of ``pd.show_versions()``

#### Code Sample, a copy-pastable example
```python
import pandas as pd
pd.DataFrame([]).astype({})
```
#### Problem description
I've got some generic code handling a large number of DataFrames, and among other things, forcing the data types of certain columns. Some of these DataFrames can be empty - however, that should not stop the calculations.
My expectation would be that I can run any operation that is conceptually a `nop` on a DataFrame without causing an issue. In this case, I can run `.astype({})` on any DataFrame (empty or not) that has columns - so far, so good. However, on a DataFrame with 0 columns, the function fails with a `ValueError`: "No objects to concatenate"
#### Expected Output
Empty DataFrame
#### Output of ``pd.show_versions()``

IIUC without changes to other scripts, activating GitHub actions for merge would push the docs. so this is only for PRs
If works. will open PR against master instead. and backport.

**Note**: Please read [this guide](https://matthewrocklin.com/blog/work/2018/02/28/minimal-bug-reports) detailing how to provide the necessary information for us to reproduce your bug.
#### Code Sample, a copy-pastable example
```python
import pandas as pd
df = pd.DataFrame(
{"e1_timestamp": [],
"e2_timestamp": []
}
)
# The problematic code. Remove this and there are no exceptions.
for timefield in [
"e1_timestamp",
"e2_timestamp",
]:
df[timefield] = pd.to_datetime(df[timefield], utc=True)
#
df = df.append({
"orderId": 1,
"e1_timestamp": pd.to_datetime(pd.NaT, utc=True),
"e2_timestamp": pd.to_datetime(pd.NaT, utc=True),
},ignore_index=True,)
df
```
#### Problem description
Why initializing an empty dataframe, defining its type as shown in the example and then appending a value, there is an ```AssertionError: Number of Block dimensions (1) must equal number of axes (2)``` exception.
If we remove the for loop, it does work:
```
df = pd.DataFrame(
{"e1_timestamp": [],
"e2_timestamp": []
}
)
df = df.append({
"e1_timestamp": pd.to_datetime(pd.NaT, utc=True),
"e2_timestamp": pd.to_datetime(pd.NaT, utc=True),
},ignore_index=True,)
df
```
We see that we could do ```df = df.astype({"e1_timestamp": 'datetime64[ns]', "e1_timestamp": 'datetime64[ns]'})``` instead of that for loop, but there seems to be a bug in this new version. With pandas==1.0.5 the for loop does not raise an exception.
#### Expected Output
There should be no assertion error
#### Output of ``pd.show_versions()``

I expected the behavior of 1.0.5 in 1.1.0, did I misunderstood the apply method?
Thank you for your help.

- [x] I have checked that this issue has not already been reported.
- [x] I have confirmed this bug exists on the latest version of pandas. -- I can't tell if this is a feature or a bug.
- [ ] (optional) I have confirmed this bug exists on the master branch of pandas.
---
**Note**: Please read [this guide](https://matthewrocklin.com/blog/work/2018/02/28/minimal-bug-reports) detailing how to provide the necessary information for us to reproduce your bug.
#### Code Sample, a copy-pastable example
```python
>>> import pandas as pd
>>> import numpy as np
>>> dt = pd.Series(np.array([1, 300], dtype='timedelta64[s]'))
>>> df = pd.DataFrame({'dt': dt})
```
```python
>>> pd.__version__
'1.0.5'
>>> df
dt
0 00:00:01
1 00:05:00
```
```python
>>> pd.__version__
'1.1.0'
>>> df
dt
0 0 days 00:00:01
1 0 days 00:05:00
```
#### Problem description
"0 days" started to appear when DataFrame contains `timedelta64[s]`.
#### Expected Output
See "Code Sample" for `pandas` 1.0.5.
#### Output of ``pd.show_versions()``
See "Code Sample" for `pandas` 1.1.0.

Tested on Pandas v1.1.0
I'm trying to import a JSON file containing the following:
**test.json**
````json
{"file_path": null}
````
If I run the following code,
````python
pd.read_json("test.json", typ='series').to_dict()
````
I get this output:
````python
{'file_path': NaT}
````
Why is `null` getting converted to `NaT` instead of `None`?

- [x] I have checked that this issue has not already been reported.
- [x] I have confirmed this bug exists on the latest version of pandas.
- [ ] (optional) I have confirmed this bug exists on the master branch of pandas.
---
**Note**: Please read [this guide](https://matthewrocklin.com/blog/work/2018/02/28/minimal-bug-reports) detailing how to provide the necessary information for us to reproduce your bug.
The creation of a pandas Series with any dtype other than `timedelta64[ns]` is discarding values and setting the entire series to `0`'s. Whereas `numpy.array` and `pd.TimeDelta` are correctly instantiating and preserving the passed values which can be retrieved by a type-cast too.
#### Code Sample, a copy-pastable example
```python
>>> import pandas as pd
>>> pd.__version__
'1.1.0'
>>> pd.Series([1000000, 200000, 3000000], dtype='timedelta64[ns]')
0 0 days 00:00:00.001000
1 0 days 00:00:00.000200
2 0 days 00:00:00.003000
dtype: timedelta64[ns]
>>> pd.Series([1000000, 200000, 3000000], dtype='timedelta64[s]')
0 0 days
1 0 days
2 0 days
dtype: timedelta64[ns]
>>> pd.Series([1000000, 200000, 3000000], dtype='timedelta64[s]').astype('int')
0 0
1 0
2 0
dtype: int64
>>> pd.Series([1000000, 200000, 3000000], dtype='timedelta64[ns]').astype('int')
0 1000000
1 200000
2 3000000
dtype: int64
>>> import numpy as np
>>> np.array([1000000, 200000, 3000000], dtype='timedelta64[ns]')
array([1000000, 200000, 3000000], dtype='timedelta64[ns]')
>>> np.array([1000000, 200000, 3000000], dtype='timedelta64[s]')
array([1000000, 200000, 3000000], dtype='timedelta64[s]')
>>> np.array([1000000, 200000, 3000000], dtype='timedelta64[s]').astype('int')
array([1000000, 200000, 3000000])
>>> pd.Timedelta(10)
Timedelta('0 days 00:00:00.000000010')
>>> pd.Timedelta(10, unit='s')
Timedelta('0 days 00:00:10')
>>> pd.Timedelta(10, unit='ns')
Timedelta('0 days 00:00:00.000000010')
```
#### Problem description
The expected behaviour is Series initialization must be in-line with numpy array initialization in this case.
#### Expected Output
#### Output of ``pd.show_versions()``

**Note**: Please read [this guide](https://matthewrocklin.com/blog/work/2018/02/28/minimal-bug-reports) detailing how to provide the necessary information for us to reproduce your bug.
#### Code Sample, a copy-pastable example
Version 1.0.5
```python
holidays = USFederalHolidayCalendar().holidays()
>>> datetime.datetime(2018, 7, 4) in holidays
True
>>> datetime.date(2018, 7, 4) in holidays
True
>>> pd.__version__
'1.0.5'
```
Version 1.1.0
```python
holidays = USFederalHolidayCalendar().holidays()
>>> datetime.datetime(2018, 7, 4) in holidays
True
>>> datetime.date(2018, 7, 4) in holidays
False
>>> pd.__version__
'1.1.0'
>>>
```
#### Problem description
On version 1.0.5 it was possible to compare via __contains__ a *datetime.date* object against a DatetimeIndex, this behavior is not true anymore for the 1.1.0, is this an expected behavior to allow only recognized scalars objects?
#### Expected Output
Allow dates to be compared with 00:00:00 time.
#### Output of ``pd.show_versions()``

- [X] I have checked that this issue has not already been reported.
- [X] I have confirmed this bug exists on the latest version of pandas.
- [ ] (optional) I have confirmed this bug exists on the master branch of pandas.
---
#### Problem description
It seems to be ignoring `errors='ignore'` kwarg. The behavior in 0.25.3 is expected.
#### Code Sample, a copy-pastable example
```python
import pandas as pd
pd.__version__
# '1.0.5'
pd.Series(pd.Categorical(['A', 'B'])).astype(float, errors='ignore')
# ---------------------------------------------------------------------------
# ValueError Traceback (most recent call last)
# <ipython-input-4-3d39cd9c1cdd> in <module>
# ----> 1 pd.Series(pd.Categorical(['A', 'B'])).astype(float, errors='ignore')
#
# ...
# ValueError: could not convert string to float: 'A'
```
#### Expected Output
```python
import pandas as pd
pd.__version__
# '0.25.3'
pd.Series(pd.Categorical(['A', 'B'])).astype(float, errors='ignore')
# 0 A
# 1 B
# dtype: category
# Categories (2, object): [A, B]
```
#### Output of ``pd.show_versions()``

#### Is your feature request related to a problem?
It should be easy to find the nth weekday of period (usually a month). This kind of operation comes up all the time in financial contracts (i.e. futures and options expiring on the 3rd Wed of the month) and other use-cases (i.e. US election dates).
#### Describe the solution you'd like
Add an `nth_weekday` method to the `pd.Period` object to handle this operation. It could then be extended to the `PeriodArray`.
`nth_weekday` should work forward and backwards with Pythonic-indexing (n=0 gives you date of first weekday, n=-1 gives you date of last weekday)
`nth_weekday` should have a flag to to enforce that the returned date has to be inside the period, or if you let it go outside the period bounds. It should default to enforcing the period bounds.
#### API breaking implications
This will add a new method to the `pd.Period` and the `PeriodArray`. Proposed name is `nth_weekday` but that can be changed. It shouldn't have any other impact on the API.
#### Describe alternatives you've considered
A general search of the internet did not find any convenient solution for this in all of Python. These looked like the best solutions available, and they're not great:
https://stackoverflow.com/questions/11883058/nth-weekday-calculation-in-python-whats-wrong-with-this-code
https://stackoverflow.com/questions/61106105/python-how-to-find-the-nth-weekday-of-the-year
#### Additional context
Below is a quick mock-up of the method (unoptimised, undocumented, but illustrates the functionality).
```python
import pandas as pd
class Period_(pd.Period):
def nth_weekday(self, n:int, weekday:int, within_period:bool=True) -> pd.Timestamp :
assert weekday >= 0
assert weekday <= 6
if n >= 0:
diff = weekday - self.start_time.weekday()
diff += 7 if diff < 0 else 0
diff = diff + n * 7
res = self.start_time + pd.Timedelta(days=diff)
if within_period:
if res > self.end_time:
res = pd.NaT
return res
if n < 0:
diff = weekday - self.end_time.weekday()
diff -= 7 if diff > 0 else 0
diff = diff + (n+1) * 7
res = self.end_time.normalize() + pd.Timedelta(days=diff)
if within_period:
if res < self.start_time:
res = pd.NaT
return res
```
Some examples of use:
```
# third Wednesday
Period_('2020-09', 'M').nth_weekday(n=2, weekday=2)
# first Friday
Period_('2020-09', 'M').nth_weekday(n=0, weekday=4)
# last Monday
Period_('2020-09', 'M').nth_weekday(n=-1, weekday=0)
# sixth Tuesday --> returns NaT when within_period=True
Period_('2020-09', 'M').nth_weekday(n=6, weekday=1)
# sixth Tuesday --> returns a date in the next month if user explicitly
# specifies within_period=False
Period_('2020-09', 'M').nth_weekday(n=6, weekday=1, within_period=False)
```
Some details would need to be ironed out on how to handle frequencies less than one day (i.e. an Hour). The mock example has some protection because `within_period` defaults to `True`, so any op that goes to a different day (not the day the hour occurrs on), it will return `NaT`.
```
# Trying to shift from a smaller freq can return NaT
Period_('2020-01-01 15:00', 'H').nth_weekday(n=0, weekday=3)
Period_('2020-01-01 15:00', 'H').nth_weekday(n=1, weekday=2)
```
The mock still needs handling of corner cases: if you ask for the `n=0` instance of the day that the hour occurs on, you get the start_time back (rather than `NaT`). Will need to put in some thought for handling these corner cases.
```
# This hour period occurs on a Wed. If I ask for the n=0 Wed of that Period, it gives me the start_time back.
Period_('2020-01-01 15:00', 'H').nth_weekday(n=0, weekday=2)
```
I'm happy to work on this but wanted to raise an issue for discussion in case there already exists such a function somewhere (couldn't find one in the pandas docs) or if it has already been proposed and decided against.

#### Is your feature request related to a problem?
I wish I could use an idxmax-like function to obtain the row and column coordinates of the minimum or maximum value.
#### Describe the solution you'd like
For a `DataFrame` object `df`, the proposed function `df.dfmin` would yield a tuple `(idx, col)` where `idx` would be the index of the minimum value (or a tuple of the hierarchical index's levels) and `col` the name of the column. For multiple equal values, a tuple of values could be returned.
#### API breaking implications
None.

#### Code Sample, a copy-pastable example
```python
import numpy as np
import pandas as pd
from pandas.arrays import PandasArray
# ==== array: empty case ====
# The following could also be archived with public-only APIs:
# array_empty = pd.Series([], dtype=float).array
array_empty = PandasArray._from_sequence([], dtype=float)
assert type(array_empty.mean()) == float
assert type(array_empty.median()) == float
assert type(array_empty.sum()) == np.float64
assert type(array_empty.min()) == type(pd.NA)
assert type(array_empty.max()) == type(pd.NA)
# ==== array: single value case ====
# The following could also be archived with public-only APIs:
# array_single = pd.Series([1.0], dtype=float).array
array_single = PandasArray._from_sequence([1.0], dtype=float)
if pd.__version__ == "1.1.0":
assert type(array_single.mean()) == np.float64
assert type(array_single.median()) == np.float64
else:
# master (3b1d4f1eef46a45b7d32694bb263a2e40a933e74)
assert type(array_single.mean()) == float
assert type(array_single.median()) == float
assert type(array_single.sum()) == np.float64
assert type(array_single.min()) == np.float64
assert type(array_single.max()) == np.float64
# ==== series: empty case ====
series_empty = pd.Series([], dtype=float)
assert type(series_empty.mean()) == float
assert type(series_empty.median()) == float
assert type(series_empty.sum()) == np.float64
assert type(series_empty.min()) == float
assert type(series_empty.max()) == float
# ==== series: single value case ====

if pd.__version__ == "1.1.0":
assert type(series_single.mean()) == np.float64
assert type(series_single.median()) == np.float64
else:
# master (3b1d4f1eef46a45b7d32694bb263a2e40a933e74)
assert type(series_single.mean()) == float
assert type(series_single.median()) == float

assert type(series_single.min()) == float
assert type(series_single.max()) == float
```
#### Problem description
As shown above, the return types for `PandasArray`s is highly inconsistent within the case as well as compared to the non-empty case.
This also extends to the `Series` cases, where I don't understand the behavior at all, especially when looking the outputs from `master`.
#### Expected Output
A single output type (either `np.float64`) or `pd.NA`? To be honest, I am not sure what the expected outcome is, but it would be good to clarify that because other extension arrays should probably implement the same behavior.
#### Output of ``pd.show_versions()``

- [ ] I have checked that this issue has not already been reported.
- [ ] I have confirmed this bug exists on the latest version of pandas.
- [ ] (optional) I have confirmed this bug exists on the master branch of pandas.
---
**Note**: Please read [this guide](https://matthewrocklin.com/blog/work/2018/02/28/minimal-bug-reports) detailing how to provide the necessary information for us to reproduce your bug.
#### Code Sample, a copy-pastable example
```python
# Your code here
```
#### Problem description
I work on frappe framework and I have `docker-erpnext` to deploy application.
When I tried to install pandas library on my linux (alpine) system, I received error:
https://travis-ci.org/github/Monogramm/docker-erpnext/jobs/713250724#L4417
By the way, this library can be installed on debian and debian-slim, but cannot be installed on alpine.
I already checked problem #7512 but it did not helped to me.
#### Expected Output
Pandas should be installed
#### Output of ``pd.show_versions()``
`pandas==0.24.2`
version of python: 3.7
<details>
[paste the output of ``pd.show_versions()`` here leaving a blank line after the details tag]

#### Code Sample, a copy-pastable example
```python
import pandas as pd
series = pd.Series([1, 2, 3])
x = series[lambda s: s > 2] # Indexing with a boolean function, works like a charm
y = series[lambda s: True] # Indexing with a constant boolean function --> results in KeyError: True
```
#### Problem description
I would expect `y` to be equal to `series` in this example, because the callable function passed to `__getitem__` returns True for all items in the Series. The same error arises when using a DataFrame. I know in this example, it seems like the function would be useless, because it would just return `series`, but in my use case the function that is passed to `__getitem__` is actually a 'filter' function argument, and it would be very convenient to just turn off the filter by passing `lambda df: True` as the filter function.
A quick workaround I found useful is:
```python
import numpy as np
y = series[lambda s: np.full(len(s), True)]
```

It looks like some `.intersection` tests are failing. AFAICT this traces back to here:
https://github.com/pandas-dev/pandas/blob/bdcc5bffaadb7488474b65554c4e8e96a00aa4af/pandas/_libs/lib.pyx#L685
Which on numpy dev during test execution isn't raising an `OverflowError` and instead performs a wraparound. Interestingly enough, running:
```python
np.asarray([2 ** 63, 2**63 + 1], dtype="int64")
```
With numpydev does overflow in the Python space, so perhaps a Cython issue?

#### Is your feature request related to a problem?
Currently, a user can use the abbreviation for an offset (e.g. "W" for week) in various methods, and will see offsets used in the docs, but the mapping from abbreviation to offset (pandas._libs.tslibs.offsets.prefix_mappings) is not public. It doesn't seem possible to answer through the public API: "what offset does this abbreviation correspond to?"
I noticed that there is a [table in the user guide](https://github.com/pandas-dev/pandas/blob/master/doc/source/user_guide/timeseries.rst#dateoffset-objects) that seems to summarize the info contained in prefix_mapping, which is really helpful! However, it would be useful to access it programmatically (e.g. for programmatically listing options to a user).
#### Describe the solution you'd like
What do you think about moving `prefix_mapping` back into pandas.tseries.offsets.prefix_mapping, and making it part of the public API? Based on the docs, it sounds like including it in the "Date offsets" section of the API docs would be sufficient for it to be considered public.
#### API breaking implications
It seems like this action would carry the same risk of API breaking as using the abbreviations in methods like `to_period()` and `as_freq()`, so shouldn't create additional risk (but could be totally wrong here :).
#### Describe alternatives you've considered
The other option would be to put the abbreviation info onto the offset classes themselves, so that the mappings emerge from the classes, but that seems like it'd be a much bigger change!

#### Question about pandas
```python
import pandas as pd
def test_func(row):
row['c'] = str(row['a']) + str(row['b'])
row['d'] = row['a'] + 1
return row
df = pd.DataFrame({'a': [1,2,3], 'b': ['i','j', 'k']})
df.apply(test_func, axis=1)
```
The above code ran on pandas 1.1.0 returns:
```
a b c d
0 1 i 1i 2
1 1 i 1i 2
2 1 i 1i 2
```
While in pandas 1.0.5 it returns:
```
a b c d
0 1 i 1i 2
1 2 j 2j 3
2 3 k 3k 4
```
Using python 3.8.3 and IPython 7.16.1.
## The Question:
:question: What is the right way of getting the v1.0.5 behavior in v1.1.0?
I did see this release note but honestly can't figure out if this is an intended/unintended side effect of it: https://pandas.pydata.org/pandas-docs/stable/whatsnew/v1.1.0.html#apply-and-applymap-on-dataframe-evaluates-first-row-column-only-once

#### Code Sample, a copy-pastable example
Hey--I noticed while running [siuba's](https://github.com/machow/siuba) SQL unit tests that queries using the modulo operator are failing.
The issue is due to a recent change for issue #34211 in pandas setting the [no_parameters](https://github.com/pandas-dev/pandas/blame/5507452c4a675ad5453bc5f02cd68b65fe3977df/pandas/io/sql.py#L1161) argument before executing via a sqlalchemy engine. This was done to allow queries like `SELECT 1 % 2`, but causes SqlAlchemy expressions handling `%` to not always work with `read_sql`.
**Solution**. Rather than executing in a special way (`no_parameters`), I think you want to wrap a string query in SqlAlchemy.sql.text ([see here](https://docs.sqlalchemy.org/en/13/core/tutorial.html#using-textual-sql)). This will allow both queries with `%` and the full range of SqlAlchemy expressions. WDYT?
```python
from sqlalchemy import sql, create_engine
import pandas as pd
engine = create_engine('postgresql://postgres:@localhost:5433/postgres', echo=False)
#engine = create_engine('postgresql://USERNAME:PASSWORD@localhost:PORT/DBNAME', echo=False)
# doesn't work, original issue in pandas: 'dict' object does not support indexing
engine.execute("SELECT 1 % 2")
# works, ideal solution
engine.execute(sql.text("SELECT 1 % 2" ))
# queries below broken by no_parameters change ----
pd.read_sql(sql.text("SELECT 1 % 2"), engine)
pd.read_sql(sql.select([sql.literal(1) % sql.literal(2)]), engine)
```
Here's a gist of the error for the last two queries...
```
ProgrammingError: (psycopg2.errors.UndefinedFunction) operator does not exist: integer %% integer
LINE 1: SELECT 1 %% 2
^
HINT: No operator matches the given name and argument types. You might need to add explicit type casts.

#### Question about pandas
Let's say we have a `DataFrame` like the below.
```python
>>> pdf = pd.DataFrame({"a": [1, 2, 3, 2], "b": [4.0, 2.0, 3.0, 1.0], "c": [10, 20, 30, 20]})
>>> pdf
a b c
0 1 4.0 10
1 2 2.0 20
2 3 3.0 30
3 2 1.0 20
```
Then, when I use `GroupByRolling`, In the version of pandas <= 1.0.5 shows result as below.
```python
>>> pdf.groupby('a')[['b']].rolling(2).max()
b
a
1 0 NaN
3 2 NaN
2 1 NaN
3 2.0
```
However, In the pandas 1.1.0, the result seems different from the previous version as below.
```python
>>> pdf.groupby('a')[['b']].rolling(2).max()
a b c
a
1 0 NaN NaN NaN
2 1 NaN NaN NaN
3 2.0 2.0 20.0
3 2 NaN NaN NaN
```
Could someone let me know Is it intended? or unexpected behavior (maybe kind of bug) ?
Thanks :)

There are a lot of starting points (epochs), which leads to different modifications of the Julian date. It can help save memory and disk space in a very long time-series, because it will use less digits in the representation.
Good list: [https://en.wikipedia.org/wiki/Julian_day#Variants](https://en.wikipedia.org/wiki/Julian_day#Variants)
The use case will be something like this:
```python
tm = pd.Timestamp('2018-01-05')
tm_jd = tm.to_julian_date() # Julian Date
tm_mjd = tm.to_julian_date(kind='MJD') # Modified Julian Date
tm_tjd = tm.to_julian_date(kind='TJD') # Truncated Julian Date
```
I'm not sure about the name `kind=` and is it necessary to add arbitrary epoch as `pandas.Timestamp` object.

- [x] I have checked that this issue has not already been reported.
- [x] I have confirmed this bug exists on the latest version of pandas.
- [ ] (optional) I have confirmed this bug exists on the master branch of pandas.

**Note**: Please read [this guide](https://matthewrocklin.com/blog/work/2018/02/28/minimal-bug-reports) detailing how to provide the necessary information for us to reproduce your bug.
#### Code Sample, a copy-pastable example
```python
# Your code here
In [1]: import pandas as pd
In [2]: import numpy as np
In [3]: df1 = pd.DataFrame(np.random.randint(1000, size=(5, 3)))
In [4]: df2 = pd.DataFrame(np.random.randint(1000, size=(5, 2)))
In [5]: df3 = pd.concat([df1, df2], axis=1)
In [6]: df3
Out[6]:
0 1 2 0 1
0 61 536 154 766 179
1 484 18 15 787 766
2 391 171 715 836 654
3 914 969 765 824 950
4 169 414 759 16 666
In [7]: len(df3._data.blocks)
Out[7]: 2
In [9]: df3.shift(2, axis=1)
Out[9]:
0 1 2 0 1
0 NaN NaN 61.0 NaN NaN
1 NaN NaN 484.0 NaN NaN
2 NaN NaN 391.0 NaN NaN
3 NaN NaN 914.0 NaN NaN
4 NaN NaN 169.0 NaN NaN
```
#### Problem description
[this should explain **why** the current behaviour is a problem and why the expected output is a better solution]
I guess `shift` is applied to both of the internal blocks.
#### Expected Output
I forced consolidate, the result is right.
```
In [12]: df3._data._consolidate_inplace()
In [13]: df3.shift(2, axis=1)
Out[13]:
0 1 2 0 1
0 NaN NaN 61.0 536.0 154.0
1 NaN NaN 484.0 18.0 15.0
2 NaN NaN 391.0 171.0 715.0
3 NaN NaN 914.0 969.0 765.0
4 NaN NaN 169.0 414.0 759.0

#### Code Sample, a copy-pastable example
```python
# Your code here
In [1]: import pandas as pd
In [2]: df1 = pd.DataFrame({
...: 'a': [3, 4, 5, 3, 5, 4, 1, 2, 3],

...: 'c': list('aabaaddce'),
...: 'd': [3, 4, 5, 3, 5, 4, 1, 2, 3],
...: 'e': [1, 3, 4, 5, 6, 5, 4, 4, 4],
...: 'f': list('aabaaddce'),

Cumulative functions should generate the DataFrame with the same length.

#### Location of the documentation
`pandas.core.frame::compare`
#### Documentation problem
Right now there is not a note/warning that you can only compare dataframes with the same shape and index labels.
#### Suggested fix for documentation
Add note:
> Note: the method can only compare identically-labeled DataFrame objects, this means DataFrames with identical row and column labels.

- [x] I have checked that this issue has not already been reported.
- [x] I have confirmed this bug exists on the latest version of pandas.
- [ ] (optional) I have confirmed this bug exists on the master branch of pandas.
---
#### Code Sample to Reproduce Error
```python
import pandas as pd
import numpy as np
pd.set_option('use_inf_as_na', True)
pd.DataFrame({'test_data':[1,3,4,np.nan]}).to_csv('test_data.csv', na_rep='NaN')
pd.read_csv('test_data.csv',sep=',' ,na_values='NaN')
```
Causes `ValueError`:

There was previously a bug where grouping on precisely two rows of a MultiIndex would return a wrongly formatted index. This PR is adding a test to enforce this correct behaviour. The new test fails on 0.20.3 but passes on >=1.0.5.

This is in between a documentation issue and a general question.
#### Location of the documentation
[`pd.read_sql()`](https://github.com/pandas-dev/pandas/blob/v1.1.0/pandas/io/sql.py#L441-L443)
#### Documentation problem
The documentation notes that if the `con` is a `SQLAlchemy connectable` that the user is responsible for disposing/closing. The documentation doesn't note whether the connection is closed if the user provides a `str` to the `con` parameter. In my quick search, I couldn't find a reference to `.dispose()`/`.close()` in the source code when the user provides a `str` type `con`. Is this connection being closed? Is it being left up to garbage collection as noted in [SQLAlchemy docs](https://docs.sqlalchemy.org/en/13/core/connections.html#engine-disposal)?
#### Suggested fix for documentation
I think a note about connection closure for `str` type `con`s would be a nice addition. Right now, if I'm understanding correctly, the connection is being garbage collected and the user needs to infer from the docs that they don't need to worry about an open connection.
Current wording:
> The user is responsible for engine disposal and connection closure for the SQLAlchemy connectable.
Potential wording:
> The user is responsible for engine disposal and connection closure for the SQLAlchemy connectable; str connections are closed automatically.

- [x] closes #35392
- [x] tests added / passed
- [x] passes `black pandas`
- [x] passes `git diff upstream/master -u -- "*.py" | flake8 --diff`
- [x] whatsnew entry
Looking at the implementation in index.pyx, I notice that when `[np.nan]` is passed to `get_indexer_non_unique`, the code was not able to get passed the `__contains__` method for stargets (line 314).
Further testing (python=3.7.7, numpy=1.18.5):
```
import numpy as np
# Case 1: Does not work -> prints nothing
# nan dtype: np.float64, ndarray dtype: np.float64
targets = np.array([np.nan])
# Case 2: Works -> prints 0, 1, 2
# nan dtype: U3, ndarray dtype: <U32
targets = np.array([np.nan, 'var1'])
values = np.array([np.nan, 'var1', np.nan])
stargets = set(targets)
for i, v in enumerate(values):
if v in stargets:
print(i)
```
Case 1 and 2 results differ because of the dtype of nan (U3 vs float64).
Upon further research, I figured out that np.nan != np.nan as per IEEE (when it is a float) and creating a set from a np.array could lead to some bizarre results (https://github.com/numpy/numpy/issues/9358). Also, since a dictionary is the main data structure in this method to keep track of the targets indices, I don't think it is ideal to use nans as keys (https://stackoverflow.com/questions/6441857/nans-as-key-in-dictionaries).
I thought it would be appropriate to replace nans (with 0s) in the targets and values arrays in order to avoid the problems stated above. When considering where to replace the nans, I thought of two places where it could potentially happen:
1. In `get_indexer_non_unique` (/pandas/core/indexes/base.py)
2. In `get_indexer_non_unique` (/pandas/_libs/index.pyx)
Including the changes in 1. would mean overwriting the the Index object's properties, so I decided to include the changes in 2.
FYI -- I wasn't sure if the test I included was in the correct file. Please let me know if you would like this test to be in another file.

- [x] I have checked that this issue has not already been reported.
- [x] I have confirmed this bug exists on the latest version of pandas.
- [ ] (optional) I have confirmed this bug exists on the master branch of pandas.
---
#### Code Sample, a copy-pastable example
I tried to pinpoint the specific row which causes the error. The column has HTML data like this:
`
'''<div class="comment" dir="auto"><p dir="auto">Request <a href="/agent/tickets/test" target="_blank" rel="ticket">#test</a> "RE: ** M ..." Last comment in request </a>:</p> <p dir="auto"></p> <p dir="auto">Thank you</p> <p dir="auto">Stuff.</p> <p dir="auto">We will keep you posted .</p> <p dir="auto">Regards,</p> <p dir="auto">Name</p></div>'''`
```python
#This fails (memory error below):
df['event_html_body'].astype("string")
#Filtering the dataframe to only convert rows which are not null for this field **works**
x = df[~df.event_html_body.isnull()][['event_html_body']]
x['event_html_body'].astype("string")
#Filling NAs with another value fails:
df['event_html_body'].fillna('-').astype("string")
```
#### Problem description
I have code which has been converting columns to the "string" dtype and this has worked up until pandas 1.1.0
For example, I tried to process a file which I successfully processed in April and it works when I use .astype(str), but it fails when I use .astype("string") event though this worked in pandas 1.0.5.
The column does not **need** to be the new "string" type, but I wanted to raise this issue anyways.
Rows: 201368
Empty/null rows for the column in question: 189014 / 201368
So this column is quite sparse, and as I mentioned below if I filtered the nulls and then do .astype("string") then it will run fine. I am not sure why this worked before (same server, 64 GB of RAM), and this file was previous processed as a "string" before the update.
Error:
```

Previously, there was a bug in `DataFrameGroupBy.apply` where a column of `datetime.date` would raise a `ValueError` if it was included as column in a multi-column grouping. Somewhere in the grouping the values would be converted to `pd.Timestamp` and then when the `pd.Timestamp` couldn't be found in the index of `datetime.date`s it would throw an error.
This bug persisted until 1.0.5 but was fixed in 1.1.0 (not sure which change fixed it). In 1.1.0 the `datetime.date` are not converted to `pd.Timestamp`, so they are treated like any other dtype=object and left unchanged.
This PR adds a test to enforce this behaviour to make sure the bug does not arise again.

#### Location of the documentation
[https://pandas.pydata.org/docs/dev/reference/api/pandas.ExcelWriter.html?highlight=excelwriter](https://pandas.pydata.org/docs/dev/reference/api/pandas.ExcelWriter.html?highlight=excelwriter)
or
[https://github.com/pandas-dev/pandas/blob/d9fff2792bf16178d4e450fe7384244e50635733/pandas/io/excel/_base.py#L544](https://github.com/pandas-dev/pandas/blob/d9fff2792bf16178d4e450fe7384244e50635733/pandas/io/excel/_base.py#L544)
#### Documentation problem
Parameter `path` has type `str`, but based on this feature [https://github.com/pandas-dev/pandas/issues/7074](url) I can pass `io.BytesIO`.
#### Suggested fix for documentation
Change type description to `str | io.BytesIO`.

I'm just not sure if I needed to add `IndexingError` to raises section. Added it to be safe, will remove if it's unnecessary.
Also, when someone uses `df.loc[df['col'] > 0]` it really is the same under the hood, `df['col'] > 0` is a boolean series with an alignable index. So there might be some overlap?

I find any DataFrame saved in v1.1.0 by `to_pickle` is not readable under v1.0.3. Any functions on the DataFrame will throw `AttributeError: 'DataFrame' object has no attribute '_data'` or `RecursionError: maximum recursion depth exceeded while calling a Python object`.
I use pip to install pandas.

- [x] I have checked that this issue has not already been reported.
- [x] I have confirmed this bug exists on the latest version of pandas.
- [ ] (optional) I have confirmed this bug exists on the master branch of pandas.

**Note**: Please read [this guide](https://matthewrocklin.com/blog/work/2018/02/28/minimal-bug-reports) detailing how to provide the necessary information for us to reproduce your bug.
#### Code Sample, a copy-pastable example
```python
>>> import pandas as pd
>>> df = pd.DataFrame(
... {'col1': ['a', 'b', 'c'], 'col2': [1, 2, 3]},
... index=pd.to_datetime(['2020-08-01', '2020-07-02', '2020-08-05'])
... )
>>> df['2020-08']
---------------------------------------------------------------------------
AssertionError Traceback (most recent call last)
<ipython-input-82-c8d0440364af> in <module>
----> 1 df['2020-08']
~/book_env/lib/python3.7/site-packages/pandas/core/frame.py in __getitem__(self, key)
2880 # either we have a slice or we have a string that can be converted
2881 # to a slice for partial-string date indexing
-> 2882 return self._slice(indexer, axis=0)
2883
2884 # Do we have a (boolean) DataFrame?
~/book_env/lib/python3.7/site-packages/pandas/core/generic.py in _slice(self, slobj, axis)
3546 Slicing with this method is *always* positional.
3547 """
-> 3548 assert isinstance(slobj, slice), type(slobj)
3549 axis = self._get_block_manager_axis(axis)
3550 result = self._constructor(self._mgr.get_slice(slobj, axis=axis))
AssertionError: <class 'numpy.ndarray'>
```
You now have to run `sort_index()` before slicing:
```python
>>> df.sort_index()['2020-08']
col1 col2
2020-08-01 a 1
2020-08-05 c 3
```
#### Problem description
Before 1.1.0, you didn't have to sort the index before slicing. Now, you have to run `sort_index()` and the error message is not helpful at all.
#### Expected Output
```python
>>> df['2020-08']
col1 col2
2020-08-01 a 1
2020-08-05 c 3
```

df.sort_values(by=[col]) -
If column(=col) has some values occurring multiple times then it orders them randomly. Instead, it should inherit the order in the DataFrame for the rows having same value for column.

#### Code Sample, a copy-pastable example
```python
import pandas as pd
# Sum, looks kinda OK
>>> pd.Series('a b c d'.split()).sum()
'abcd'
>>> pd.Series('1 2 3 4'.split()).sum()
'1234'
# Mean, inconsistent behaviour
>>> pd.Series('a b c d'.split()).mean()
...
TypeError: Could not convert abcd to numeric
>>> pd.Series('1 2 3 4'.split()).mean()
308.5
```
I saw the last example in a #26927 comment, scanned the code to see what's wrong and eventually decided to open this issue.
#### Problem description
IMO When calculating the mean, data type conversion should either happen on each element of the series before applying sum or should happen in the end. Here, to calculate the mean of `['1', '2', '3', '4']`, first a `sum` concatenates all the elements keeping the dtype, then it's converted to float (1234) and then divided by 4 which results in 308.5.
#### Expected Output
I have 3 options in mind:
1. an element-wise type conversion, which means:
```python
>>> pd.Series('a b c d'.split()).sum() # and mean
Type Error
>>> pd.Series('1 2 3 4'.split()).sum()
10
>>> pd.Series('1 2 3 4'.split()).mean()
2.5
```
2. throwing an error in these cases or adding a note in docs for consequences of performing these aggregations on an object dtype. For example, considering that `np.sum(np.array('a b c d'.split()))` fails with a TypeError it's not intuitive that the same function in pandas performs a concatenation.
https://github.com/pandas-dev/pandas/blob/d9fff2792bf16178d4e450fe7384244e50635733/pandas/core/generic.py#L10410
just like what happens when dtype is explicitly set as 'string':
```python
>>> pd.Series('1 2 3 4'.split(), dtype='string').mean()
...
TypeError: Cannot perform reduction 'mean' with string dtype
```
3. No type conversions in the middle of calculating the mean: (It's not a good option IMHO for all the side effects it will have)
```python
>>> pd.Series('a b c d'.split()).sum()
'abcd'
>>> pd.Series('a b c d'.split()).mean()
TypeError while trying to compute 'abcd' / 4, but not because 'abcd' cannot be converted to a number, but bc a string cannot be divided by a number
>>> pd.Series('1 2 3 4'.split()).sum()
'1234'
>>> pd.Series('1 2 3 4'.split()).mean()
TypeError while trying to '1234' / 4
```

This fix introduced two regression, but it appears like the fix only made the API consistent. Previously the failing regressions where inconsistent say `df1.combine_first(df2)` would not return the same result as `df2.combine_first(df1)` for the failing cases, more on these in the code comments.
Let me know if there is a better way to handle this.

The error occurs with
```python
df = pd.DataFrame({"A": [2, 1, 1, 1, 2, 2, 1], "B": pd.Series(np.full(7, np.nan), dtype="Int64")})
df.groupby("A").std()
```
while now we have `df.groupby("A").var()` working correctly.
- [ x] I have checked that this issue has not already been reported.
- [x ] I have confirmed this bug exists on the latest version of pandas.
- [ ] (optional) I have confirmed this bug exists on the master branch of pandas.
