Until recently, this was a wart in the Python standard library: datetime objects exist in the 'datetime' module, but parsing strings to get date/time components was only available in the 'time' module. In Python 2.5, though, we have 'datetime.datetime.strptime' <URL:http://docs.python.org/lib/datetime-datetime.html#l2h-634>, which parses a string according to a specified format, and returns the corresponding datetime value. >>> import datetime >>> datetime.datetime.strptime("2007-10-16t17:40:00", "%Y-%m-%dt%H:%M:%S") datetime.datetime(2007, 10, 16, 17, 40) > now once this is done I will create a another date object with > today = datetime.datetime.now() > and then see the difference between this today and the string that I > converted to date. That's simple: datetime objects support difference via the subtraction arithmetic operator, returning a datetime.timedelta instance <URL:http://docs.python.org/lib/datetime-timedelta.html>. >>> value = datetime.datetime(2007, 10, 16, 15, 30, 45) >>> value - datetime.datetime(2007, 10, 16, 15, 20, 00) datetime.timedelta(0, 645) >>> value - datetime.datetime(2007, 10, 12, 8, 25, 19) datetime.timedelta(4, 25526) >>> value - datetime.datetime(2007, 11, 26, 0, 0, 0) datetime.timedelta(-41, 55845) -- \ "Experience is that marvelous thing that enables you to | `\ recognize a mistake when you make it again." -- Franklin P. | _o__) Jones | Ben Finney -- http://mail.python.org/mailman/listinfo/python-list
