[Python-Dev] iso8601 parsing (original) (raw)

IIRC, arrow usually calls dateutil to parse dates anyway, and there are many other, lighter dependencies that will parse an ISO 8601 date quickly into a datetime.datetime object.

I still think it's reasonable for the .isoformat() operation to have an inverse operation in the standard library.

I think the latest version can now strptime offsets of the form ±HH:MM with %z, so there's no longer anything blocking you from parsing from all isoformat() outputs with strptime, provided you know which one you need. Or just punt and install arrow:

import arrow arrow.get('2017-10-20T08:20:08.986166+00:00') <Arrow [2017-10-20T08:20:08.986166+00:00]> arrow.get('2017-10-20T08:20:08.986166+00:00').datetime datetime.datetime(2017, 10, 20, 8, 20, 8, 986166, tzinfo=tzoffset(None, 0)) Skip -------------- next part -------------- An HTML attachment was scrubbed...
