Roy Smith added the comment: We need to define the scope of what input strings will be accepted. ISO-8601 defines a lot of stuff which we may not wish to accept.
Do we want to accept both basic format (YYYYMMDD) and extended format (YYYY-MM-DD)? Do we want to accept things like "1985-W15-5", which is (if I understand this correctly(), the 5th day of the 15th week of 1985 [section 4.1.4.2]. Do we want to accept [section 4.2.2.4], "23:20,8", which is 23 hours, 20 minutes, 8 tenths of a minute. I suspect most people who have been following the recent thread (https://groups.google.com/d/topic/comp.lang.python/Q2w4R89Nq1w/discussion) would say none of the above are needed. All that's needed is if you have an existing datetime object, d1, you can do: s = str(d1) d2 = datetime.datetime(s) assert d1 == d2 for all values of d1. But, let's at least agree on that. Or, in the alternative, agree on something else. Then we know what we're shooting for. ---------- nosy: +roysmith _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue15873> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
