gh-127552: Remove comment questioning 4-digit restriction for ‘Y’ in datetime.strptime patterns (#127590) 
The code has required 4 digits for the year since its inclusion in the stdlib in 2002 (over 22 years ago as of this commit).

gh-53203: Fix strptime() for %c and %x formats on many locales (GH-124946) 
In some locales (like French or Hebrew) the full or abbreviated names of
the default month and weekday used in __calc_date_time can be part of
other name or constant part of the %c format. The month name can also
match %m with constant suffix (like in Japanese). So the code failed to
correctly distinguish formats %a, %A, %b, %B and %m.

Cycle all month and all days of the week to find the variable part
and distinguish %a from %A and %b from %B or %m.

Fixed locales for the following languges:
Arabic, Bislama, Breton, Bodo, Kashubian, Chuvash, Estonian, French, Irish,
Ge'ez, Gurajati, Manx Gaelic, Hebrew, Hindi, Chhattisgarhi, Haitian Kreyol,
Japanese, Kannada, Korean, Marathi, Malay, Norwegian, Nynorsk, Punjabi,
Rajasthani, Tok Pisin, Yoruba, Yue Chinese, Yau/Nungon and Chinese.

bpo-43295: Fix error handling of datetime.strptime format string '%z' (GH-24627) 
Previously, `datetime.strptime` would match `'z'` with the format string `'%z'` (for UTC offsets), throwing an `IndexError` by erroneously trying to parse `'z'` as a timestamp. As a special case, `'%z'` matches the string `'Z'` which is equivalent to the offset `'+00:00'`, however this behavior is not defined for lowercase `'z'`.

This change ensures a `ValueError` is thrown when encountering the original example, as follows:

```
>>> from datetime import datetime
>>> datetime.strptime('z', '%z')
ValueError: time data 'z' does not match format '%z'
```

7f6b4f86e3 Make sure time.strptime only accepts strings (and document the fact like 
strftime). Already didn't accept bytes but make the check earlier. This also
lifts the limitation of requiring ASCII.
