I know how to do this the other way around... it would be:
>>> dt.rfc822()
'Sun, 09 Mar 1997 13:45:00 -0500'
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)
in python3 parsedate_tz has moved to 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)
As of python 3.3 there is 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)))
If you strip off the time zone, you can do it like this:
datetime.datetime.strptime('Sun, 09 Mar 1997 13:45:00', '%a, %d %b %Y %H:%M:%S')
