Documentation: Error in datetime.datetime.strptime()

Documentation

The documentation for datetime.datetime.strptime is incorrect:

cpython/Doc/library/datetime.rst

Lines 1048 to 1050 in bb8b931

	This is equivalent to::
	datetime(*(time.strptime(date_string, format)[0:6]))

This is incorrect if format contains microseconds or timezone information. Counterexample:

>>> timestr = '20200304050607.554321'
>>> print(datetime.strptime(timestr, '%Y%m%d%H%M%S.%f'))
2020-03-04 05:06:07.554321
>>> print(datetime(*(time.strptime(timestr, '%Y%m%d%H%M%S.%f')[0:6])))
2020-03-04 05:06:07

I suggest removing the cited part entirely, since since I see no easy way of correcting these lines, especially concerning timezones.
