Well, I did know that any attribute used explicitly with a class instance is looked up in the class, then the base class etc: class Base: variable = 1 class Child(Base): pass child = Child() print child.variable 1 What I did not know was that the __init__ method behaves the same way - i.e. that Python looks for __init__ upon instantiation until it finds one. Thanks, Jan -- A good programmer is someone who looks both ways before crossing a one-way street. - Doug Linder _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
