I have a code snippet like this

class A(object):
    class b:
        def print_hello(self):
            print "Hello world"
    b = property(b)

And I want to override the inner class b (please dont worry about the lowercase name) behaviour. Say, I want to add a new method or I want to change an existing method, like:

class C(A):
    class b(A.b):
        def print_hello(self):
            print "Inner Class: Hello world"
    b = property(b)

Now if I create C's object as c = C(), and call c.b I get TypeError: 'property' object is not callable error. How would I get pass this and call print_hello of the extended inner class? Disclaimer: I dont want to change the code for A class.
