I figured it out like this: >>> v = Vehicle() >>> dir(v) ['__class__', '__delattr__', '__dict__', '__doc__', '__format__', '__getattribut e__', '__hash__', '__init__', '__module__', '__new__', '__reduce__', '__reduce_e x__', '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__', '_ _weakref__', 'fault'] Cool stuff. -- > Odeyemi 'Kayode O. > http://www.sinati.com. t: @charyorde > > -- Odeyemi 'Kayode O. http://www.sinati.com. t: @charyorde -- http://mail.python.org/mailman/listinfo/python-list
