I wrote the below code

    class foo:
        pass
    class bar(object, ):
        pass
    class baz1(foo, bar, ):
        pass
    class baz2(bar, foo, ):
        pass
    AreEqual(baz1.__bases__, (foo, bar))
    AreEqual(baz2.__bases__, (bar, foo))
    class foo:
        abc = 3
    class bar(object, ):
        def get_abc():
            return 42
        def set_abc():
            pass
        abc = property(fget=get_abc, fset=set_abc)
    class baz(foo, bar, ):
        pass
    AreEqual(baz().abc, 3)
