Behavior of datetime.datetime.strptime differs from documented behavior on %z #122781
Description
Bug report
Bug description:
import datetime
datetime.datetime.strptime("2024-03-21T15:49:51", '%Y-%m-%dT%H:%M:%S%z')will fail with ValueError: time data '2024-03-21T15:49:51' does not match format '%Y-%m-%dT%H:%M:%S%z'
From the documentation for strptime, empty string should be allowed here.
| %z | UTC offset in the form ±HHMM[SS[.ffffff]] (empty string if the object is naive). | (empty), +0000, -0400, +1030, +063415, -030712.345216 | (6) |
|---|
NB: strftime behaves correctly.
>>> datetime.datetime.strftime(datetime.datetime(2024, 3, 21, 15, 49, 51), '%Y-%m-%dT%H:%M:%S%z')
'2024-03-21T15:49:51'So strptime(strftime(datetime.datetime(2024, 3, 21, 15, 49, 51), '%Y-%m-%dT%H:%M:%S%z'), '%Y-%m-%dT%H:%M:%S%z') would fail.
