I guess I do not get it.


>>> class A(object):
...   def f(self):
...     print 'Af'
... 
>>> class B(object):
...   def f(self):
...     print 'Bf'
... 
>>> class C(A, B):
...   def f(self):
...     super(C, self).f()
... 
>>> c=C()
>>> c.f()
Af


Should this be showing
Af
Bf
?

How would I even get that output?  I know I can do:

class C(A, B):
  def f(self):
    A.f(self)
    B.f(self)


but I can't seem to get that out of super()
