Test case:

>>> import datetime
>>> datetime.datetime.fromisoformat('2021-12-10T01:00:00Z')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: Invalid isoformat string: '2021-12-10T01:00:00Z'


Basically every other programming language I tested correctly accepted this ISO/RFC3339 string as a date.

fromisoformat() is only designed to parse the output of isformat().

See issue 35829 for further discussion. I'm going to close this issue as a duplicate.
