If you subclass from a new-style class (almost all classes in the standard lib are...), you don't need to anything more.Else, yes, inherit from 'object', or set 'type' as the metaclass. Both classes defined below are 'new-style' classes: class Parrot: __metaclass__ = type class CheeseChop(object): pass And now: class DeadParrot(Parrot): pass is a new-style class too. > Where will I find a document that provides info on the > use of object in new style classes? In the Fine Manual(tm), of course. Googling python.org for "type unification" or "new-style" should give relevant answers. -- http://mail.python.org/mailman/listinfo/python-list
