The docs you linked to are for the latest Python 3 release (currently 3.13). The 3.10 docs for datetime.datetime.fromisoformat() doesn't have that example because Z is not supported in that version.

3.10 is also only receiving security updates at this point, so we wouldn't be able to fix it even if there was a bug unfortunately.

Welp, I feel a bit silly for the wrong docs.
I know there is no bug fixing, but would it be possible to update the documentation at datetime.isoformat() from
'Return a string representing the date and time in ISO 8601 format' to
'Return a string representing the date and time in an ISO 8601 compliant format' ?
I read that first line and assumed it could output anything ISO 8601 [definitely my bad], but a bit of clarity might help prevent similar reports in the future.
