You'll want to use the __new__ method, see http://www.python.org/2.2.3/descrintro.html#__new__ Example: >>> def int5(): ... '''return 5''' ... return 5 ... >>> class my_int(int): ... def __new__(self): ... return int.__new__(self, int5()) ... >>> i = my_int() >>> i 5 >>> As someone else pointed out, you probably ought to call int.__init__ as well. _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
