'''
Write a program that asks the user for their name and year of birth.
If there is no error in the name or year, they are added to the tuple list.
When the user replaces the name with an empty string, the program prints the list and terminates.
See the sample output below for a description of how the program should react to various error situations.
The earliest accepted year of birth is 1800, the minimum length of the name is 2 characters.
The program assumes that the year is 2021 - so the person cannot have been born after that date.
Name: Alex
Year of birth: 1904
Name: Lena
Year of birth: 1999
Name: A
Year of birth: 1987
Name's too short!
Name: Alex
Year of birth: 1765
You're too old!
Name: Tina
Year of birth: 2042
You're not born yet!
Name: Mark
Year of birth: in the fifties
Year must be given in a numerical form!

List: [('Alex', 1904), ('Lena', 1999)]
