Ah, I agree - if you see that's how my __round__ implementation works. I guess that's another problem with the semantics of `round` (which are assumed to round to the nearest whole number). I suppose we could implement __floor__, but then you have the counter-intuitive property that in order to get access to this method, you have to import `math.floor`. We could add a `datetime.truncate()` method, maybe, and not try to be clever about overloading existing operations. Or punt on the idea of truncation in general and do what I proposed in the original thread and have all the truncation happen in `now`. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue32522> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
