>>> import datetime
>>> t1 = datetime.datetime(2005, 6, 8, 12, 30)
>>> t2 = datetime.datetime(2005, 6, 10, 15, 30)
>>> t = datetime.datetime(2005, 6, 9, 14, 00)
>>> if t1 < t < t2:
... print "In range"
...
In range
>>> t = datetime.datetime(2005, 6, 8, 14, 00)
>>> if t1 < t < t2:
... print "In range"
...
In range
>>> t = datetime.datetime(2005, 6, 7, 14, 00)

If you want to use the "in" syntax
>>> class InRange:
... def __init__(self, low, high):
... self.low = low
... self.high = high
... def __contains__(self, obj):
... return self.low < obj < self.high
...
>>> r = InRange(t1, t2)
>>> datetime.datetime(2005, 6, 7, 14, 00) in r
False
>>> datetime.datetime(2005, 6, 8, 14, 00) in r
True
>>> datetime.datetime(2005, 6, 9, 14, 00) in r
True
>>> datetime.datetime(2005, 6, 9, 18, 00) in r
True
>>> datetime.datetime(2005, 6, 10, 18, 00) in r
False
>>>
