Converting strings to dates

[Chermside, Michael]

I'm trying to convert a string back into a datetime.date.

First I'll create the string:


Python 2.4 (#60, Nov 30 2004, 11:49:19) [MSC v.1310 32 bit (Intel)] on
win32
Type "help", "copyright" , "credits" or "license" for more information.[color=blue][color=green][color=darkred]
>>> import time, datetime
>>> a_date = datetime.date.t oday()
>>> s = str(a_date)
>>> print s[/color][/color][/color]
2005-02-04

Now I convert it back:
[color=blue][color=green][color=darkred]
>>> new_date = datetime.date.f romtimestamp([/color][/color][/color]
.... time.mktime(tim e.strptime(s, '%Y-%m-%d')))[color=blue][color=green][color=darkred]
>>> new_date[/color][/color][/color]
datetime.date(2 005, 2, 4)


WOW, that's ugly. Is there a more concise way to do this?

py> import time
py> date_str = time.strftime(' %Y-%m-%d', time.localtime( ))
py> date_str
'2005-02-04'
py> time.strptime(d ate_str, '%Y-%m-%d')
(2005, 2, 4, 0, 0, 0, 4, 35, -1)

That work?

datetime.date(* map(int, s.split("-")))
