It helps to post the actual code and error message you
are seeing...



>>> import datetime
>>> class foo(datetime):
...   pass
...
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
TypeError: function takes at most 2 arguments (3 given)
>>> class foo(datetime.datetime):
...   pass
...
>>> d = foo()
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
TypeError: function takes at least 3 arguments (0 given)
>>> d = foo(1, 2, 3)
>>> d
foo(1, 2, 3, 0, 0)
>>> datetime.datetime(1, 2, 3)
datetime.datetime(1, 2, 3, 0, 0)



My guess is that the code you posted is not really the
code you were runnning.
