In Python 3.11+ datetime.datetime.fromisoformat( accepts any number of decimal places in the seconds component, extra digits are truncated (not rounded)
>>> datetime.datetime.fromisoformat('2011-11-04T00:05:23.1234567Z')
datetime.datetime(2011, 11, 4, 0, 5, 23, 123456, tzinfo=datetime.timezone.utc)

@alex Yes, prior to 3.11, we were only accepting formats that could be generated from datetime.isoformat. In 3.11, we added the ability to parse most valid ISO 8601 formats, including many that are acceptable only “by agreement”.
I don’t recall if we had a principled reason for choosing truncation rather than rounding.
@pganssle TBC it's an "oo nice" TIL. The truncation bit was more a footnote. Thank you for adding it.
