Parse this date in Python: 5th November 2010
I'm having a bad time with date parsing and formatting today.
Points for somebody who can parse this date format into a datetime.date
or datetime.datetime
(I'm not too fussy but I'd prefer .date
):
5th November 2开发者_如何学编程010
Using dateutil:
In [2]: import dateutil.parser as dparser
In [3]: date = dparser.parse('5th November 2010')
In [4]: date
Out[4]: datetime.datetime(2010, 11, 5, 0, 0)
Unfortunately, strptime
has no format characters for "skip an ordinal suffix" -- so, I'd do the skipping first, with a little RE, and then parse the resulting "clear" string. I.e.:
>>> import re
>>> import datetime
>>> ordn = re.compile(r'(?<=\d)(st|nd|rd|th)\b')
>>> def parse(s):
... cleans = ordn.sub('', s)
... dt = datetime.datetime.strptime(cleans, '%d %B %Y')
... return dt.date()
...
>>> parse('5th November 2010')
datetime.date(2010, 11, 5)
Your preference for date
vs datetime
is no problem of course, that's what the .date()
method of datetime
objects is for;-).
Third-party extensions like dateutil can be useful if you need to do a lot of "fuzzy" date parsing (or other fancy date-related stuff;-), by the way.
If the ordinal is constant then:
datetime.strptime(s, '%dth %B %Y')
Else:
date_str = '5th November 2010'
modified_date_str = date_str[0:1] + date_str[3:]
datetime.strptime(modified_date_str, '%d %B %Y')
Or like ~unutbu said use dateutil :)
