If you write them this way: > ------------ Exampel 1: ----------------------------- > > class B(A): > def __init__(self, *args): > A.__init__(self, *args) > > ------------ Exampel 2: ----------------------------- > > class B(A): > def __init__(self, *args): > apply( A.__init__, (self,) + args) > > ------------ Exampel 3: ----------------------------- > > class B(A): > def __init__(self, *args): > super(B,self).__init__(*args) then 2 is exactly the same as 1 but using a deprecated function. And 3 is the same as 1 only when there is single inheritance involved (and you are using new-style classes). But see the thread "super() doesn't get superclass" -- Gabriel Genellina -- http://mail.python.org/mailman/listinfo/python-list
