Follow-ups to #30640 based on @jbrockmendel's comments. Haven't addressed all the comments yet but pushing this up now so there's a record of it. Changes thus far: - Created `tests/arithmetic/test_interval.py ` and moved the tests there - Used `make_wrapped_comparison_op` to add `__eq__` and `__ne__` to `IntervalArray`.

## Overview Using `pandas==0.25.1` with `Python 3.7.1` on Debian, loading the following JSON lines file fails using `pandas.read_json()` but succeeds when read manually. After looking into this a bit, I think it might be related to `NaN` in the JSON file which is not supported by the spec but accepted by `json.loads()`. If that turns out to be the case, it would be good to have an option to ignore those entries or at least provide a detailed error message. Data file: https://gist.github.com/danijar/37ba75a6991d61de9e77755329bb5ef4 ## Manual Reading the file manually using `json.loads()` and passing it to a `pd.DataFrame` works fine: ```python import json import pandas as pd with open(filename) as f: df = pd.DataFrame([json.loads(l) for l in f.readlines()]) print(df) # Shows data frame as expected ``` <details><summary>Terminal output</summary> ```text step train/return train/length episodes ... value_loss action_loss action_ent fps 0 1000 1.0 500.0 1.0 ...

This will take a few passes to do comprehensively, but trying to clean up error handling in the extension module. Right now failure points are allowed, which can lead to segfaults or surprising behaviour when debugging. Trying to push closers towards the CPython error handling conventions: https://docs.python.org/3/c-api/exceptions.html So basically: - Explicitly check for NULL from most C API functions except integer returning functions (where they return -1 and set PyErr) AND - Don't set error messages from failing functions, as they should have already set it

There are 2 remaining non-cosmetic differences between these methods remaining, which will be the subjects of upcoming PRs. Once those are addressed, we'll be able to de-duplicate the methods completely.

One of the two non-cosmetic things mentioned in #30720. There are a bunch of places where DTA or DTI do a compatibility check that for tz_awareness_compat, but not requiring the same tz. This check is analogous to `PeriodArray._check_compatible_with` and `TimedeltaArray._check_compatible_with`, so this adds a kwarg to _check_compatible_with so that we can use _check_compatible_with in all the relevant places and subsequently de-duplicate a bunch of code. In addition to the comparisons, this is going to be relevant for searchsorted and insert, where we have slightly different behavior in a bunch of EA/Index subclasses.

#### Code Sample ```python import pandas as pd import numpy as np import skimage from scipy import signal for orient in [0, 1]: th = int(input_img.shape[orient] / 100) peaks, info = signal.find_peaks(1 - bw_img.mean(orient), prominence=.35, width=2) for pk, w in zip(peaks, info['widths']): w *= 2 if orient == 0: sign = bw_img[:, pk] else: sign = bw_img[pk, :] sign = pd.Series(sign).rolling(th).max() ``` #### Problem description The above snippet is part of a function called in my main script. Running this results in either a `malloc: Incorrect checksum for freed object 0x7fbf626f1f30: probably modified after being freed.` error or a segmentation fault. The culprit appears to be the `rolling().max()` line, since commenting out the line fixes the issue, as does replacing `.max()` with `.mean()`. I can't seem to recreate the error running the above snippet alone, and I cannot figure out why. The input (`bw_img`) is just a 2D array (black and white image). It might be related to this issue https://github.com/pandas-dev/pandas/issues/25893 expect my memory doesn't seem to be leaking. The two variants I keep seeing seem to be a checksum failed after changing deallocated memory, or that an attempted change of deallocated memory is caught. python version: 3.6.5 (also tested on 3.7.0) pandas version 0.25.3 (also tested 0.24 and 0.23) Below the stacktrace: ``` Process: python3.6 [61410] Path: /Users/USER/*/python3.6 Identifier: python3.6 Version: ???

The changes associated with #27991 (merged as part of v0.25.1) changed the behavior of `DataFrame._repr_html_()` We use monkey patching to allow the automatic display (within Jupyter notebooks) of chemical structures stored in DataFrames as part of the RDKit project. Given how useful it is to be able to automatically render specialized data types in DataFrames, I would assume we're not the only ones doing this. For those who are interested, here's an example from the RDKit community demonstrating what this looks like - https://www.blopig.com/blog/2017/02/using-rdkit-to-load-ligand-sdfs-into-pandas-dataframes/ Previous to v0.25.1 we could simply monkey patch `DataFrame.to_html()` since it was called by `DataFrame._repr_html_()`, but now it looks like we need to patch both methods. Doing this kind of patching is always a bit fraught and having to do it twice really seems to be begging for support problems down the road. Note: A single patch to `DataFrameFormatter.to_html()` would also be possible, but it looks like that would make it impossible to for us to disable the specialized rendering on a DataFrame by DataFrame basis. I'm happy to submit a PR with a fix if the maintainers agree that re-unifying these two is desirable. I think this should probably be classified as a Cleanup item, but I didn't want to presume.

#### Code Sample ```python import pandas as pd pd.show_versions() today = pd.to_datetime("today") df = pd.DataFrame({'date': [today]}) assert isinstance(today, pd.Timestamp) assert str(df.date.dtype) == 'datetime64[ns]' delta = df.date - today # works fine assert str(delta.dtype) == 'timedelta64[ns]' df.eval("date - @today") # fails ``` Live demo: https://repl.it/repls/SelfassuredFrighteningNumber #### Problem description Subtraction works 'normally' but not when used inside DataFrame.eval or .query.

Until 2019-11-02, https://7933911d6844c6c53a7d-47bd50c35cd79bd838daf386af554a83.ssl.cf2.rackcdn.com/ contains nightly builds of pandas for different platforms. Is there any chance that this will be continued? I am asking because nightly testing is very helpful for some downstream artifacts to discover unintentional breaking chances or regressions before a new pandas version gets released. Building pandas from source on CI takes very long though, up to a duration where it gets kinda unpractical for downstream projects.

#### Code Sample, a copy-pastable example if possible ```python def aggfunc(df): # operation that rely on df having the grouping column present. # Goes in again here without the grouping key and if my operation would rely on this, it would fail. return pd.Series([0.2,0.2], index=[12,13]) mydf=pd.DataFrame({"a":[datetime.datetime.today(),datetime.datetime.today()],"b":[1,2],"c":[5,6]}) mydf.groupby("a").apply(aggfunc) ``` Looks like groupby.apply crashes when using datetime aggregation and returning non-datetime data. The problem is here: `pandas.core.groupby.generic._recast_datetimelike_result` `/pandas/core/groupby/generic.py:1857` ``` obj_cols = [ idx for idx in range(len(result.columns)) if is_object_dtype(result.dtypes[idx]) ] ``` E.g. My result columns are 12,13 and this is trying to iterate through the 0,1 which is the range. The code in `/pandas/core/groupby/generic.py:1857` will fail with the above and an exception will be caught here: `pandas/core/groupby/groupby.py:726`. because of gh-20949 it is trying again without the grouping key. It should have worked from the beggining and this exception is not there to catch this kind of error. The work around for this is to return a Series or DataFrame with the index reset, however this should not be a requirement. The right way is to not use range in the `_recast_datetimelike_result` function.

I'm not sure if this issue belongs to `pandas` or `s3fs`. When writing to non-existing bucket or bucket without proper permissions no exception is raised. E.g. the following code will be executed normally: ```python df = pd.DataFrame({'col1': [1, 2], 'col2': [3, 4]}) df.to_csv('s3://very.weird.and.certainly.nonexistent.bucket/data.csv') # No exception ``` In contrast, when writing to a local file without proper permissions results in an exception as it should be: ```python dff.to_csv('/data.csv') # PermissionError: [Errno 13] Permission denied: '/data.csv' ``` #### Output of ``pd.show_versions()`` <details> INSTALLED VERSIONS ------------------ commit : None python : 3.7.1.final.0 python-bits : 64 OS : Darwin OS-release : 18.7.0 machine : x86_64 processor : i386 byteorder : little LC_ALL : en_US.UTF-8 LANG : en_US.UTF-8 LOCALE : en_US.UTF-8 pandas : 0.25.3 numpy : 1.17.2 pytz : 2019.3 dateutil : 2.8.1 pip : 19.3.1 setuptools : 42.0.1.post20191125 Cython : None pytest : 5.3.0 hypothesis : None sphinx : 2.2.0 blosc : None feather : None xlsxwriter : None lxml.etree : 4.4.1 html5lib : None pymysql : 0.9.3 psycopg2 : None jinja2 : 2.10.1 IPython : 7.8.0 pandas_datareader: None bs4 : 4.6.3 bottleneck : None fastparquet : 0.3.2 gcsfs : None lxml.etree : 4.4.1 matplotlib : 3.0.1 numexpr : 2.7.0 odfpy : None openpyxl : None pandas_gbq : None pyarrow : 0.12.1 pytables : None s3fs : 0.4.0 scipy : 1.3.1 sqlalchemy : 1.3.8 tables : 3.4.4 xarray : None xlrd : 1.1.0 xlwt : None xlsxwriter : None </details>

#### The following is a MWE of the error: ```python # Create an index from_, to_ = pd.to_datetime(['2016-01-01', '2016-06-01']) index = pd.date_range(from_, to_, freq='1min') hour = pd.Timedelta('1h') # Disorder the index: index = pd.to_datetime(np.random.choice(index, len(index), replace=False)) # Create a DF using that index df = pd.DataFrame(np.arange(2*len(index)).reshape(-1, 2), index = index) # Now, select date-range: df[from_:to_] # ----> Fine! (Unordered) df[df.index[2]:to_] # ----> Fine! (Unordered) df[from_:to_ + hour] # ----> KeyError: Timestamp('2016-06-01 01:00:00') df[str(from_):str(to_ + hour)] # ----> Fine (Unordered) df.sort_index()[from_:to_ + hour] # ----> Fine (Ordered) ``` #### Problem description There are quite a few problems with this behavior: 1. It's counter-intuitive that the query will succeed when such slight changes cause differences in behavior. 1. The error-message on the 3nd case is very uninformative, considering what has to be done to fix this problem (sort/convert to string). 1. How come this query works when using items that are already within the index as ranges, but not when using external datetimes? 1. How come using the internal datatype `Timestamp` yields worse results compared to using the external type (`str`)? #### <Details> INSTALLED VERSIONS ------------------ commit : None python : 3.6.8.final.0 python-bits : 64 OS : Linux OS-release : 5.0.0-37-generic machine : x86_64 processor : x86_64 byteorder : little LC_ALL : None LANG : en_US.UTF-8 LOCALE : en_US.UTF-8 pandas : 0.25.3 numpy : 1.17.1 pytz : 2019.3 dateutil : 2.8.1 pip : 19.3.1 setuptools : 43.0.0 Cython : None pytest : 5.3.2 hypothesis : None sphinx : None blosc : None feather : None xlsxwriter : None lxml.etree : None html5lib : None pymysql : None psycopg2 : None jinja2 : 2.10.3 IPython : 7.8.0 pandas_datareader: None bs4 : None bottleneck : None fastparquet : None gcsfs : None lxml.etree : None matplotlib : 3.1.1 numexpr : 2.7.0 odfpy : None openpyxl : None pandas_gbq : None pyarrow : None pytables : None s3fs : None scipy : 1.3.1 sqlalchemy : None tables : 3.6.1 xarray : None xlrd : 1.2.0 xlwt : None xlsxwriter : None </Details``>

Currently, the following does not work (but probably should): ``` In [12]: arr1 = pd.array([1, 2, 3]) In [13]: arr2 = pd.array([0, 2]) In [14]: arr1[arr2] --------------------------------------------------------------------------- IndexError Traceback (most recent call last) <ipython-input-14-1646c66d4d26> in <module> ----> 1 arr1[arr2] ~/scipy/pandas/pandas/core/arrays/integer.py in __getitem__(self, item) 375 item = check_bool_array_indexer(self, item) 376 --> 377 return type(self)(self._data[item], self._mask[item]) 378 379 def _coerce_to_ndarray(self, dtype=None, na_value=lib._no_default): IndexError: only integers, slices (`:`), ellipsis (`...`), numpy.newaxis (`None`) and integer or boolean arrays are valid indices ``` So that raises the following questions: - This should probably simply work for the above case? (converting the IntegerArray to a numpy integer array, instead of object array, so numpy's indexing works) We might want to combine this with the boolean array checking? - What if there are missing values? This should probably simply raise an error for now (which is what pandas 0.25 also does), although we could consider propagating an NA value as well, I think. For Series, this seems to work partly. For `iloc` it works for the case without missing values. For `__getitem__` you get the same error as above.

Would it make sense to remove `tests` folder from the pandas distribution? It takes roughly 33% of the whole package weight. It is especially important when using pandas inside the AWS Lambdas, where the deployment package size is limited to 50 MB zipped and 5 MB might really make a difference. ``` # Uncompressed du -h -s pandas* 46.5M pandas 30.9M pandas_no_tests # Compressed du -h -s pandas* 14.7M pandas.zip 10.1M pandas_no_tests.zip ```

Currently we do not support multi row inserts into sqlite databases when `to_sql` is passed `method="multi"` - despite the documentation suggesting that this is supported. Adding support for this is straightforward - it only needs us to implement a single method on the SQLiteTable class and so this PR does just that. - [x] closes #29921 - [x] tests added / passed - [x] passes `black pandas` - [x] passes `git diff upstream/master -u -- "*.py" | flake8 --diff` - [x] whatsnew entry

Recent regression in the `categoricals.CategoricalSlicing.time_getitem_list` benchmark: https://pandas.pydata.org/speed/pandas/#categoricals.CategoricalSlicing.time_getitem_list?commits=6efc2379-b9de33e3 Reproducible example for this benchmark: ``` N = 10 ** 6 categories = ["a", "b", "c"] values = [0] * N + [1] * N + [2] * N data = pd.Categorical.from_codes(values, categories=categories) list_ = list(range(10000)) %timeit data[list_] ``` Now, this slowdown is due to the changes in https://github.com/pandas-dev/pandas/pull/30308. Categorical `__getitem__` now checks if the key is a boolean indexer: https://github.com/pandas-dev/pandas/pull/30308/files#diff-f3b2ea15ba728b55cab4a1acd97d996d So this slowdown is of course expected, and also only for Categorical itself (eg pd.Series indexing already handles this boolean checking). So in that light, we can certainly ignore this regression. But, this led me think: maybe the ExtensionArrays are a good place to start not supporting object dtype as boolean indexer? (and so not add support for it now, which also avoids this performance regression)

Closes https://github.com/pandas-dev/pandas/issues/30735 This avoids using _DeprecatedModule, which doesn't work for direct imports from a module. Sorry for the importlib magic, but I think this is the correct way to do things. cc @jorisvandenbossche.

- [X] xref #28822 - [x] tests added / passed - [X] passes `black pandas` - [X] passes `git diff upstream/master -u -- "*.py" | flake8 --diff` - [ ] whatsnew entry We moved our script to numpydoc, and it already had some improvements there. The script does like 80% of our validation, so what I'm doing here is to call numpydoc validation, and then call our custom validation (things that for different reasons weren't moved to numpydoc).

#### Code Sample, a copy-pastable example if possible ```python import pandas as pd df = pd.DataFrame({"A": [[1, 2], [3, 4]], "B": ["x", "y"]}, index=[0, 0]) df.explode("A") ``` Output: ``` A B 0 1 x 0 2 x 0 3 x 0 4 x 0 1 y 0 2 y 0 3 y 0 4 y ``` #### Problem description We are getting rows with e.g. `A=3` and `B=x`, which never appears in the original data. The `.explode()` method appears to be effectively combining rows with the same index value before splitting them, which is surprising at least to me. #### Expected Output ``` A B 0 1 x 0 2 x 0 3 y 0 4 y ``` #### Output of ``pd.show_versions()`` <details> INSTALLED VERSIONS ------------------ commit : None python : 3.6.9.final.0 python-bits : 64 OS : Linux OS-release : 4.14.77-70.82.amzn1.x86_64 machine : x86_64 processor : x86_64 byteorder : little LC_ALL : C.UTF-8 LANG : None LOCALE : en_US.UTF-8 pandas : 0.25.3 numpy : 1.17.2 pytz : 2019.2 dateutil : 2.8.0 pip : 19.3.1 setuptools : 41.2.0 Cython : 0.28.4 pytest : 5.2.0 hypothesis : 4.38.1 sphinx : 2.2.0 blosc : None feather : None xlsxwriter : None lxml.etree : None html5lib : None pymysql : None psycopg2 : 2.7.7 (dt dec pq3 ext lo64) jinja2 : 2.10.1 IPython : 7.8.0 pandas_datareader: None bs4 : 4.8.0 bottleneck : 1.3.1 fastparquet : None gcsfs : None lxml.etree : None matplotlib : 3.1.1 numexpr : 2.7.0 odfpy : None openpyxl : None pandas_gbq : None pyarrow : 0.15.1 pytables : None s3fs : 0.4.0 scipy : 1.3.1 sqlalchemy : 1.3.10 tables : None xarray : None xlrd : None xlwt : None xlsxwriter : None </details>

Fixes PR08 errors. When I ran the script, a lot of them seem to be false positives, these are the ones I'm pretty sure should be fixed: ``` pandas.infer_freq: Parameter "index" description should start with a capital letter pandas.MultiIndex.get_loc_level: Parameter "drop_level" description should start with a capital letter ``` Related to #27977 cc @datapythonista - [ ] closes #xxxx - [ ] tests added / passed - [x] passes `black pandas` - [x] passes `git diff upstream/master -u -- "*.py" | flake8 --diff` - [ ] whatsnew entry

If we construct MI with `nan`, and check the `levels`, output does not contain `nan`, ```python >>> tuples = [["A", "B"], ["A", np.nan], ["B", "A"]] >>> mi = pd.MultiIndex.from_tuples(tuples, names=list("ab")) >>> mi.levels FrozenList([['A', 'B'], ['A', 'B']]) ``` Tracking it down, this is due to `pd.Categorical` does not include NA in `categories`: ```python >>> pd.Categorical(['a', 'b', None]) [a, b, NaN] Categories (2, object): [a, b] ``` While `inferred_type` does indicate it is a mixed type, so `np.nan` should be accepted. ```python >>> tuples = [["A", "B"], ["A", np.nan], ["B", "A"]] >>> mi = pd.MultiIndex.from_tuples(tuples, names=list("ab")) >>> mi.inferred_type 'mixed' ``` However, if the `nan` is gotten by operations, the `nan` is included in levels, e.g. ```python >>> l = [["a", np.NaN, 12, 12], [None, "a", 12.3, 33.], ["b", np.nan, 12.3, 123], ["a", "a", 1, 1]] >>> df = pd.DataFrame(l, columns=["a", "b", "c", "d"]) >>> grouped = df.groupby(by=["a", "b"], dropna=False).sum() >>> grouped.index.levels FrozenList([['a', 'b', nan], ['a', nan]]) ``` This is quite inconsistent though, is it an intended behaviour?

This started out as a cosmetic-only branch and ended up finding a broken corner case. The relevant change is in timedeltas L416 where `if self.freq is not None:` is now `if self.size and self.freq is not None:` Using _check_compatible_with causes us to raise TypeError instead of ValueError in a couple of the DatetimeIndex.insert cases.

I don't think we want this ```python In [1]: import pandas as pd In [2]: df = pd.DataFrame({"sparse": [1, 2], "b": pd.SparseArray([1, 2])}) /Users/taugspurger/.virtualenvs/pandas-dev/bin/ipython:1: FutureWarning: The pandas.SparseArray class is deprecated and will be removed from pandas in a future version. Use pandas.arrays.SparseArray instead. #!/Users/taugspurger/Envs/pandas-dev/bin/python In [3]: df.sparse Out[3]: 0 1 1 2 Name: sparse, dtype: int64 ``` That should instead return the accessor.

- [x] closes https://github.com/pandas-dev/pandas/issues/29896 - [x] tests added / passed - [x] passes `black pandas` - [x] passes `git diff upstream/master -u -- "*.py" | flake8 --diff` - [x] whatsnew entry Addresses an issue which appears to have existed since 0.23.0 where bugs in the `get_indexer()` method for the `MultiIndex` class cause incorrect reindexing behavior for multi-indexed DataFrames. motivating, example, from (the issue) ```python >>> >>> df = pd.DataFrame({ ... 'a': [0, 0, 0, 0], ... 'b': [0, 2, 3, 4], ... 'c': ['A', 'B', 'C', 'D'] ... }).set_index(['a', 'b']) >>> >>> df c a b 0 0 A 2 B 3 C 4 D >>> df.index MultiIndex([(0, 0), (0, 2), (0, 3), (0, 4)], names=['a', 'b']) >>> mi_2 = pd.MultiIndex.from_product([[0], [-1, 0, 1, 3, 4, 5]]) >>> mi_2 MultiIndex([(0, -1), (0, 0), (0, 1), (0, 3), (0, 4), (0, 5)], ) ``` as expected, without a `method` value: ```python >>> df.reindex(mi_2) c 0 -1 NaN 0 A 1 NaN 3 C 4 D 5 NaN ``` using `method="backfill"`, it is: ```python >>> >>> df.reindex(mi_2, method="backfill") c 0 -1 A 0 A 1 D 3 A 4 A 5 C >>> ``` but should (IMHO) be: ```python >>> df.reindex(mi_2, method="backfill") c 0 -1 A 0 A 1 B 3 C 4 D 5 NaN >>> ``` similarly, using `method="pad"`, it is: ```python >>> df.reindex(mi_2, method="pad") c 0 -1 NaN 0 NaN 1 D 3 NaN 4 A 5 C ``` but should (IMHO) be: ```python >>> df.reindex(mi_2, method="pad") c 0 -1 NaN 0 A 1 A 3 C 4 D 5 D ```

Small simplification: modify the `breaks` metadata before creating an `IntervalIndex` then create and an `IntervalIndex` from the modified `breaks`. The existing approach creates an `IntervalIndex`, modifies the first `Interval`, then creates a new `IntervalIndex` with the updated first `Interval`. This yields a slight performance improvement but doesn't seem dramatic enough to warrant a whatsnew entry, though I can add one if desired. On this branch: ```python In [1]: import numpy as np; import pandas as pd; pd.__version__ Out[1]: '0.26.0.dev0+1668.ga6c08fc02' In [2]: a = np.arange(10**5) In [3]: %timeit pd.qcut(a, 10**4) 273 ms ± 914 µs per loop (mean ± std. dev. of 7 runs, 1 loop each) ``` On `master`: ```python In [1]: import numpy as np; import pandas as pd; pd.__version__ Out[1]: '0.26.0.dev0+1667.g40bff2fed' In [2]: a = np.arange(10**5) In [3]: %timeit pd.qcut(a, 10**4) 317 ms ± 1.14 ms per loop (mean ± std. dev. of 7 runs, 1 loop each) ```

## Overview I found that the number of lines increased when I read a csv file by `pd.read_csv` from S3. I also confirmed that several rows are duplicated with the transformation of types (their values are transformed into object-type). This might be related to [pandas.read_csv duplicate issue](https://stackoverflow.com/questions/51790913/pandas-read-csv-duplicate-issue) , but I cannot solve the problem by removing the `.pyc` extension file. Do you have any ideas about the reason for this phenomenon? And how should I fix the problem? ## Details The number of lines of the original S3 file is 34715 (one line is a header). ``` ***$ wc -l data/foo.csv 34715 data/foo.csv ``` I build and run the following docker image. Dockerfile: ``` FROM python:3.6.8-stretch WORKDIR .

On the other hand, the number of lines did not increase without the docker environment. ``` In [2]: df = pd.read_csv("s3://*/*.csv", converters={"foo": str}) */.pyenv/versions/3.6.1/lib/python3.6/site-packages/IPython/core/interactiveshell.py:2728: DtypeWarning: Columns (46) have mixed types.

For DataFrameGroupBy, if any group contains duplicate index, boxplot will crash. See code below for illustration, setting crash=True will give rise to duplicate index in Group 1 (2nd group), causing boxplot to crash. ``` import pandas as pd import numpy.random as rnd crash=True if crash: index = pd.date_range(start='1/1/2018', end='1/6/2018').append(pd.date_range(start='1/6/2018', end='1/15/2018')) else: index = pd.date_range(start='1/1/2018', end='1/16/2018') df = pd.DataFrame(data={'value':rnd.randn(16), 'group':[i for i in range(4) for j in range(4)]}, index=index) dfg = df.groupby('group') dfg.boxplot(subplots=False) ``` The error stack trace looks like the following: ``` --------------------------------------------------------------------------- ValueError Traceback (most recent call last) <ipython-input-51-a9576feccdf0> in <module> 11 df = pd.DataFrame(data={'value':rnd.randn(16), 'group':[i for i in range(4) for j in range(4)]}, index=index) 12 dfg = df.groupby('group') ---> 13 dfg.boxplot(subplots=False) 14 dfg ~/anaconda3/lib/python3.7/site-packages/pandas/plotting/_core.py in boxplot_frame_groupby(grouped, subplots, column, fontsize, rot, grid, ax, figsize, layout, sharex, sharey, **kwds) 498 sharex=sharex, 499 sharey=sharey, --> 500 **kwds 501 ) 502 ~/anaconda3/lib/python3.7/site-packages/pandas/plotting/_matplotlib/boxplot.py in boxplot_frame_groupby(grouped, subplots, column, fontsize, rot, grid, ax, figsize, layout, sharex, sharey, **kwds) 398 keys, frames = zip(*grouped) 399 if grouped.axis == 0: --> 400 df = pd.concat(frames, keys=keys, axis=1) 401 else: 402 if len(frames) > 1: ~/anaconda3/lib/python3.7/site-packages/pandas/core/reshape/concat.py in concat(objs, axis, join, join_axes, ignore_index, keys, levels, names, verify_integrity, sort, copy) 256 ) 257 --> 258 return op.get_result() 259 260 ~/anaconda3/lib/python3.7/site-packages/pandas/core/reshape/concat.py in get_result(self) 471 472 new_data = concatenate_block_managers( --> 473 mgrs_indexers, self.new_axes, concat_axis=self.axis, copy=self.copy 474 ) 475 if not self.copy: ~/anaconda3/lib/python3.7/site-packages/pandas/core/internals/managers.py in concatenate_block_managers(mgrs_indexers, axes, concat_axis, copy) 2057 blocks.append(b) 2058 -> 2059 return BlockManager(blocks, axes) ~/anaconda3/lib/python3.7/site-packages/pandas/core/internals/managers.py in __init__(self, blocks, axes, do_integrity_check) 141 142 if do_integrity_check: --> 143 self._verify_integrity() 144 145 self._consolidate_check() ~/anaconda3/lib/python3.7/site-packages/pandas/core/internals/managers.py in _verify_integrity(self) 343 for block in self.blocks: 344 if block._verify_integrity and block.shape[1:] != mgr_shape[1:]: --> 345 construction_error(tot_items, block.shape[1:], self.axes) 346 if len(self.items) != tot_items: 347 raise AssertionError( ~/anaconda3/lib/python3.7/site-packages/pandas/core/internals/managers.py in construction_error(tot_items, block_shape, axes, e) 1717 raise ValueError("Empty data passed with indices specified.") 1718 raise ValueError( -> 1719 "Shape of passed values is {0}, indices imply {1}".format(passed, implied) 1720 ) 1721 ValueError: Shape of passed values is (18, 8), indices imply (16, 8) ``` From practical point of view, when people use boxplot, it is not necessary to ensure no duplicate index, therefore, boxplot should work regardless of whether there exist duplicate index or not, it is irrelevant. Interestingly, DataFrame.boxplot does not crash when there exist duplicate index.

A script is easier to execute and manage as we manage our style-checking tools. Started with `flake8`, `black`, and `isort`, as those are the main ones for Python-related changes (for reference, we didn't even have `isort` in the checklist beforehand). If we're happy with the structure, we can always add more OR modify checks if we want going forward while keeping it easy for folks to check their PR's.

#### Code Sample, a copy-pastable example if possible ```python >>> df1 = pd.DataFrame() >>> df2 = pd.DataFrame() >>> df3 = pd.DataFrame() >>> df1['1'] = range(0,10) >>> df2['2'] = range(0,20,2) >>> df3['2'] = range(0,30,3) >>> df = pd.concat([df1, df2, df3], axis=1) >>> df 1 2 2 0 0 0 0 1 1 2 3 2 2 4 6 3 3 6 9 4 4 8 12 5 5 10 15 6 6 12 18 7 7 14 21 8 8 16 24 9 9 18 27 >>> df['2'] 2 2 0 0 0 1 2 3 2 4 6 3 6 9 4 8 12 5 10 15 6 12 18 7 14 21 8 16 24 9 18 27 >>> df['2'] = range(0,50,5) >>> df 1 2 2 0 0 0 0 1 1 5 5 2 2 10 10 3 3 15 15 4 4 20 20 5 5 25 25 6 6 30 30 7 7 35 35 8 8 40 40 9 9 45 45 >>> ``` #### Problem description **why** Concat on dataframes containing same column name leads to multiple entries with same column name.(it should append the columns with column_name_1 and column_name_2, similar to merge). On performing actions on the column(as shown in above example) it leads to action replicated to both the columns. **Version** 3.6.8 (default, Apr 25 2019, 21:02:35) \n[GCC 4.8.5 20150623 (Red Hat 4.8.5-36)] For documentation-related issues, you can check the latest versions of the docs on `master` here: https://pandas-docs.github.io/pandas-docs-travis/ If the issue has not been resolved there, go ahead and file it in the issue tracker. #### Expected Output #### Output of ``pd.show_versions()`` <details> [paste the output of ``pd.show_versions()`` here below this line] commit : None python : 3.6.8.final.0 python-bits : 64 OS : Linux OS-release : 3.10.0-957.12.2.el7.x86_64 machine : x86_64 processor : x86_64 byteorder : little LC_ALL : None LANG : en_US.UTF-8 LOCALE : en_US.UTF-8 pandas : 0.25.3 numpy : 1.18.0 pytz : 2019.3 dateutil : 2.8.1 pip : 18.1 setuptools : 40.6.2 Cython : None pytest : None hypothesis : None sphinx : None blosc : None feather : None xlsxwriter : None lxml.etree : None html5lib : None pymysql : None psycopg2 : None jinja2 : None IPython : None pandas_datareader: None bs4 : None bottleneck : None fastparquet : None gcsfs : None lxml.etree : None matplotlib : None numexpr : None odfpy : None openpyxl : None pandas_gbq : None pyarrow : None pytables : None s3fs : None scipy : 1.4.1 sqlalchemy : None tables : None xarray : None xlrd : None xlwt : None xlsxwriter : None </details>

Datatype converstion(.astype) error for bool type. ```python import pandas as pd pd.__version__ df_1 = pd.DataFrame({'c_bool': [None, None, True, True, True,False]}) print(df_1['c_bool'].dtypes) df_1['c_bool'] = df_1['c_bool'].astype(bool) print(df_1['c_bool'].dtypes) df_1 # '0.24.2' # object # bool # c_bool # 0 False # 1 False # 2 True # 3 True # 4 True # 5 False ``` I have a column that has some None/True/False values. Initially, the datatype of that column is 'object'. After I convert it to bool as datatype, Null values are converting to False. Which is not expected behavior.

cc @TomAugspurger I propose to keep the old deprecated imports (as long as they are not removed), so the benchmarks can still be run when eg doing a comparison of 0.25 with current master.

I see couple of `FutureWarning` in the benchmarks that can be fixed by simply updating the code to the proposed version. ``` ·· /home/runner/work/pandas/pandas/asv_bench/benchmarks/algorithms.py:8: FutureWarning: pandas.util.testing is deprecated. Use the functions in the public API at pandas.testing instead. from pandas.util import testing as tm /home/runner/work/pandas/pandas/asv_bench/benchmarks/sparse.py:5: FutureWarning: The pandas.SparseArray class is deprecated and will be removed from pandas in a future version. Use pandas.arrays.SparseArray instead. from pandas import MultiIndex, Series, SparseArray, date_range ``` See for example: https://github.com/pandas-dev/pandas/pull/30746/checks#step:13:21

#### Code Sample ```python df = pd.read_stata('xx.dta') ``` #### Problem description I was trying to use the above command to load Stata 16 data, but got an error saying ```python Version of given Stata file is not 104, 105, 108, 111 (Stata 7SE), 113 (Stata 8/9), 114 (Stata 10/11), 115 (Stata 12), 117 (Stata 13), or 118 (Stata 14) ``` I updated pandas to version 0.25.1, the issue persists. How could I load Stata 16 data without degrading the dataset? Thanks.

Closes #27357 This adds an internal version of `take` with the behaviour of setting `_is_copy` for DataFrames that the public `take` did before, so this version can be used in the indexing code (where we want to keep track of parent dataframe with `_is_copy` for SettingWithCopyWarnings). I named it `_take_with_is_copy` which is literally what it is doing, but happy to hear alternatives. This then updates the deprecation to fully ignore the keyword and indicate in the deprecation message the keyword has no effect anymore. I checked https://github.com/pandas-dev/pandas/pull/27349 and https://github.com/pandas-dev/pandas/pull/30615 to ensure that where previously the internal version was used or `is_copy` was specified, now the appropriate function is used. I suppose that in some of the cases where I now use the internal `_take_with_is_copy` this is not actually needed, but it's the safest thing anyway (it will do the same as it did before).

#### Code Sample ```python import pandas as pd series = pd.Series([0, 1, 2, 3, 4, pd.np.nan, 6, 7], dtype='Int64') breaks = [0, 2, 4, 6, 8] breaks_cut = pd.cut(series, breaks) breaks_cut ``` ``` 0 NaN 1 (0.0, 2.0] 2 (0.0, 2.0] 3 (2.0, 4.0] 4 (2.0, 4.0] 5 NaN 6 (0.0, 2.0] 7 (6.0, 8.0] dtype: category Categories (4, interval[int64]): [(0, 2] < (2, 4] < (4, 6] < (6, 8]] ``` #### Problem Description When using the `pd.Int64` nullable integer data type, `pd.cut()` unexpectedly bins the first non-`np.nan` value after an `np.nan` into the lowest interval. In the above example, the number `6` is binned into `(0.0, 2.0]`. #### Expected Output ``` 0 NaN 1 (0.0, 2.0] 2 (0.0, 2.0] 3 (2.0, 4.0] 4 (2.0, 4.0] 5 NaN 6 (4.0, 6.0] 7 (6.0, 8.0] dtype: category Categories (4, interval[int64]): [(0, 2] < (2, 4] < (4, 6] < (6, 8]] ``` Note that using an `IntervalIndex` produces the expected output. ```python import pandas as pd series = pd.Series([0, 1, 2, 3, 4, pd.np.nan, 6, 7], dtype='Int64') breaks = [0, 2, 4, 6, 8] intervals = [pd.Interval(x, y) for x, y in zip(breaks[:-1], breaks[1:])] interval_index = pd.IntervalIndex(intervals) interval_cut = pd.cut(series, interval_index) interval_cut ``` #### Output of `pd.show_versions()` <details> ``` INSTALLED VERSIONS ------------------ commit : None python : 3.7.6.final.0 python-bits : 64 OS : Linux OS-release : 5.0.0-37-generic machine : x86_64 processor : x86_64 byteorder : little LC_ALL : None LANG : en_US.UTF-8 LOCALE : en_US.UTF-8 pandas : 0.25.3 numpy : 1.17.3 pytz : 2019.3 dateutil : 2.8.1 pip : 19.3.1 setuptools : 44.0.0.post20200102 Cython : None pytest : 5.3.2 hypothesis : None sphinx : 2.3.1 blosc : None feather : None xlsxwriter : None lxml.etree : 4.4.2 html5lib : None pymysql : None psycopg2 : None jinja2 : 2.10.3 IPython : 7.11.1 pandas_datareader: None bs4 : 4.8.2 bottleneck : None fastparquet : None gcsfs : None lxml.etree : 4.4.2 matplotlib : 3.1.2 numexpr : None odfpy : None openpyxl : None pandas_gbq : None pyarrow : None pytables : None s3fs : None scipy : 1.4.1 sqlalchemy : None tables : None xarray : None xlrd : None xlwt : None xlsxwriter : None ``` </details>

I ran a full benchmark on a separate machine locally, comparing current master against 0.25.3. Some identified cases: - [x] Indexing slowdown due to `extract_array`, reproducer below at https://github.com/pandas-dev/pandas/issues/30790#issuecomment-572928516 - [ ] `Index.__new__`, reproducer below at https://github.com/pandas-dev/pandas/issues/30790#issuecomment-571959377 - [ ] IntervalIndex (or all ExtensionIndex?) attribute access: https://github.com/pandas-dev/pandas/issues/30742 - [x] `asof` due to additional copy / take: https://github.com/pandas-dev/pandas/pull/30615/#issuecomment-571531394 Full results: <details> ``` before after ratio [62a87bf4] [526b2f36] <v0.25.3^0>

commented on a few PRs, for the rest would need to take a further look. Help is certainly welcome to check certain cases. One recurrent theme seems to be a rather consistent slowdown of a bunch of groupby methods. This can also be seen on the benchmark machine (eg https://pandas.pydata.org/speed/pandas/index.html#groupby.GroupByMethods.time_dtype_as_group?p-dtype='int'&p-method='all'&p-method='any'&odfpy=)

This bug was hidden by _ensure_datetimelike_to_i8, and the only other place where that is used is in _round. _round is clearer without using it, so ensure_datetimelike_to_i8 gets ripped out, and with it we can get rid of _ensure_localized.

This implements IntegerArray.to_numpy with similar semantics to BooleanArray.to_numpy. The implementation is now identical between BooleanArray & IntegerArray. #30789 will merge them. 1. `.to_numpy(dtype=float/bool/int)` will raise if there are missing values 2. `.astype(float)` will convert NA to NaN. I've made a slight change from the BooleanArray implementation on master, which I'll annotate inline. Closes https://github.com/pandas-dev/pandas/issues/30038

#### Code Sample ```python import pandas pandas.show_versions() pandas.DatetimeIndex(['2013-01-01 09:58:29', '2013-01-01 09:58:30', '2013-01-01 09:58:30.001', '2013-01-01 09:59:29', '2013-01-01 09:59:30', '2013-01-01 09:59:30.001'], dtype='datetime64[ns]').round('min') ``` #### Problem description The rounding direction changes in the 59th minute of the hour! For minutes 00-58 the method rounds down from 30 seconds or less. For the 59th minute of the hour it rounds up to the next hour. There are a couple previous issues for rounding time in pandas, but I could not find one for this behavior. #### Expected Output Example output showing the problem using the above sample ``` Python 3.7.3 (default, Mar 27 2019, 09:23:15) Type 'copyright', 'credits' or 'license' for more information IPython 7.9.0 -- An enhanced Interactive Python. Type '?' for help. In [1]: import pandas ...: pandas.show_versions() ...: pandas.DatetimeIndex(['2013-01-01 09:58:29', '2013-01-01 09:58:30', '2013-01-01 09:58:30.001', ...: '2013-01-01 09:59:29', '2013-01-01 09:59:30', '2013-01-01 09:59:30.001'], ...: dtype='datetime64[ns]').round('min') Out[1]: DatetimeIndex(['2013-01-01 09:58:00', '2013-01-01 09:58:00', '2013-01-01 09:59:00', '2013-01-01 09:59:00', '2013-01-01 10:00:00', '2013-01-01 10:00:00'], dtype='datetime64[ns]', freq=None) ``` The rounding direction should be the same for '2013-01-01 09:58:30' and '2013-01-01 09:59:30' but it is not. The first becomes '2013-01-01 09:58:00', while the later becomes '2013-01-01 10:00:00'. #### Output of ``pd.show_versions()`` <details> INSTALLED VERSIONS ------------------ commit : None python : 3.7.3.final.0 python-bits : 64 OS : Darwin OS-release : 19.2.0 machine : x86_64 processor : i386 byteorder : little LC_ALL : None LANG : en_US.UTF-8 LOCALE : en_US.UTF-8 pandas : 0.25.3 numpy : 1.17.4 pytz : 2019.3 dateutil : 2.8.0 pip : 19.2.3 setuptools : 41.2.0 Cython : None pytest : None hypothesis : None sphinx : None blosc : None feather : None xlsxwriter : None lxml.etree : None html5lib : None pymysql : None psycopg2 : None jinja2 : 2.10.3 IPython : 7.9.0 pandas_datareader: None bs4 : None bottleneck : None fastparquet : None gcsfs : None lxml.etree : None matplotlib : 3.1.1 numexpr : None odfpy : None openpyxl : None pandas_gbq : None pyarrow : None pytables : None s3fs : None scipy : 1.3.3 sqlalchemy : None tables : None xarray : None xlrd : None xlwt : None xlsxwriter : None </details>

In https://github.com/pandas-dev/pandas/pull/29212, we bumped the minimum Python to 3.6.1. @datapythonista mentioned an issue with 3.6.0 at https://github.com/pandas-dev/pandas/pull/29212#issuecomment-551370118 > Seems like Python 3.6 has something (I guess a bug) causing the error TypeError: only integer scalar arrays can be converted to a scalar index when converting strings to bytes in some of our cases. I vaguely recall a few issues with 0.25.x requiring a point release of python 3.5. We should see if we can support 3.6.0 to save some headaches down the road.

- [x] closes #30642 - [x] tests added / passed - [x] passes `black pandas` - [x] passes `git diff upstream/master -u -- "*.py" | flake8 --diff` - [ ] whatsnew entry - N/A Turns out that the existing tests were not testing deprecation correctly for both python 3.7 and python 3.6, so had to change some of the code in `test_api.py` to make that work right. For `pd.SparseArray` in python 3.6, we can only issue a warning when the constructor `pd.SparseArray` is used. But this is consistent with `pd.datetime` and `pd.np` with python 3.6, which will issue warnings when things like `pd.datetime.now()` are called. However, for python 3.6, I could not figure out a way to issue a warning on `pd.datetime(2015, 10, 11, 0, 0)`, so we may just have to live with that.

Fixes the spelling of _dependency_ in `script/generate_pip_deps_from_conda.py`. This script creates `requirements-dev.txt` which contains the spelling mistake, so is also fixed (using the updated script).

Hey all, feature request here. While I'm exploring data in the shell, I am _constantly_ forgetting the tilde prefix to a isnull() argument. There's something about the way I conceptualize the data and how I use pandas - "Okay, I have a dataframe, now I select a subset... this column, with variables that are not null.. Oh sh*t (backarrow, backarrow, backarrow)." This happens DOZENS of times a day. I've forked a copy of the code and am looking at implementing something for myself, but I thought I'd put this up and see if there's any interest in it. Yeah, it's redundant, but I think it would be an improved design and there are other redundant functions... What do you think?

The section about imports here: https://github.com/pandas-dev/pandas/wiki/Code-Style-and-Conventions#imports-aim-for-absolute Can be moved to the code style guide in the documentation: https://dev.pandas.io/docs/development/code_style.html This way we can remove the page from the wiki, that is mostly outdated.
