Hi Tim!
I'm not sure if it's this, what you want to know. I just played around
a little:

 >>> class A:
    def __init__(self):
        self.u = 1
    def p(self):
        print self.u

       
 >>> x = A()
 >>> x.p()
1
 >>> def q(self):
    print 2*self.u

   
 >>> A.p = q
 >>> x.p()
2
 >>>

Even if it doesn't help  it's still funny
