When I run the following code and call super() in the Base class's __init__ () method, only one Parent's __init__() method is called.
class Parent1(object): def __init__(self): print "Parent1 init called." self.x = 10 class Parent2(object): def __init__(self): print "Parent2 init called." self.y = 15 class Base(Parent1, Parent2): def __init__(self): super(Base, self).__init__() self.z = 20 b = Base() --output:-- Parent1 init called. -- http://mail.python.org/mailman/listinfo/python-list
