New submission from Erik Cederstrand <e...@cederstrand.dk>:
Python 3.7 gained support for parsing ISO 8601 formatted time, date and datetime strings via the fromisoformat() methods. Python has seen improved support for ISO 8601 in general; ISO calendar format codes were added in Python 3.6, and fromisocalendar() was added in Python 3.8. ISO 8601 also has a standard for durations: https://en.wikipedia.org/wiki/ISO_8601#Durations For consistency with the other objects in the datetime module, I suggest adding isoformat()/fromisoformat() methods for datetime.timedelta that implement ISO 8601 durations. ISO 8601 durations support years and months that are not valid timedelta arguments because they are non-precise durations. I suggest throwing an exception if the conversion to or from timedelta cannot be done safely. https://pypi.org/project/isodate/ implements a parse_duration() method that could be used for inspiration. ---------- components: Library (Lib) messages: 379091 nosy: Erik Cederstrand priority: normal severity: normal status: open title: isoformat() / fromisoformat() for datetime.timedelta versions: Python 3.10 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue42094> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
