昨天如何在python中获取

Question

现在,我可以这样做:

now = datetime.datetime.now()

我怎么会在24小时前得到的？

now - 24 hrs. ?

Answer 1

用途timedelta:

datetime.datetime.now() - datetime.timedelta(days=1)

http://docs.python.org/2/library/datetime.html#timedelta-objects

Answer 2

你可以使用:

datetime.date.fromordinal(datetime.date.today().toordinal()-1)

获取昨天的Python日期,DST-safe

这将有助于格式化:
