表示日期，很方便。datetime.datetime(), datetime.date(), datetime.timedelta()

>>> d1 = datetime.date(2001,6,7)

>>> d2 = datetime.date(2008,8,5)

>>> d = datetime.date(2006,7,7)

>>> if d1 <= d <= d2:

... print 'good'

...

good

>>> delta = d2-d1

>>> delta.total_seconds()

226022400.0

>>> d = datetime.date.today()

>>> d

datetime.date(2011, 6, 24)

>>> d.year, d.month, d.day

(2011, 6, 24)
