如何将RFC822转换为python datetime对象？

Question

我知道如何以相反的方式做到这一点......它将是：

>>> dt.rfc822()
'Sun, 09 Mar 1997 13:45:00 -0500'

Answer 1

In [1]: import rfc822     # This only works for python 2 series

In [2]: rfc822.parsedate_tz('Sun, 09 Mar 1997 13:45:00 -0500')
Out[2]: (1997, 3, 9, 13, 45, 0, 0, 1, 0, -18000)

python3中的

parsedate_tz已移至email.utils

>>> import email.utils   # this works on Python2.5 and up
>>> email.utils.parsedate_tz('Sun, 09 Mar 1997 13:45:00 -0500')
(1997, 3, 9, 13, 45, 0, 0, 1, -1, -18000)

Answer 2

从python 3.3开始，有email.utils.parsedate_to_datetime(date)

>>> from email.utils import parsedate_to_datetime
>>> datestr = 'Sun, 09 Mar 1997 13:45:00 -0500'
>>> parsedate_to_datetime(datestr)
datetime.datetime(1997, 3, 9, 13, 45, tzinfo=datetime.timezone(datetime.timedelta(-1, 68400)))

Answer 3

如果你剥离时区，你可以这样做：

datetime.datetime.strptime('Sun, 09 Mar 1997 13:45:00', '%a, %d %b %Y %H:%M:%S')
