[issue14423] Getting the starting date of iso week from a week number and a year.
Esben Agerbæk Black added the comment: I somehow re-uploaded an old patch, this one contains buggy c-code, but fixes the python implementation. Any pointers to how to get started on the c bi would be greatly appreciated. -- Added file: http://bugs.python.org/file25306/isodates.patch ___ Python tracker <http://bugs.python.org/issue14423> ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Esben Agerbæk Black added the comment: 1) Yes I agree, your solution is somewhat more concise, I have corrected the code accordingly. 2) I get errors for all my test when I build "my" python and run "./python.exe -m test.datetimetester -j3" I asume this is because I have yet to implement the c version in Modules/_datetimemodule.c is this the correct assumption?

Esben Agerbæk Black added the comment: I believe that it is a good solution to have, for lack of a better term; bi-directional features so in my opinion .isocalendar() merits having a constructor that takes an ISO format. Sadly no :-( I looked it over once more and it seems there is an error where the date is not offset correctly for years beginning on Tuesday, Wednesday or Thursday. I will updater my patch ASAP. +if self.isocalendar()[1] != 1: +if self.weekday() > 3: # Jan 1 is not in week one + self += timedelta(7 - self.weekday()) +else: +self -= timedelta(self.weekday()) -- > > ___ > Python tracker > <http://bugs.python.org/issue14423> > ___ > -- ___ Python tracker <http://bugs.python.org/issue14423> ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
