Invoke a superclass method from a subclass constructor

An instance of my subclass doesn't invoke its superclass method, except when
it is referenced
Here is what I mean:
>>> class A(object):
... def log(self, module):
... return str('logged')
>>> class B(A):
... def __init__(self, module):
... self.module = A().log(module)
>>> c = B('system')
>>> # I expect 'logged' to be printed here
>>> print c.log('system') # why do I have to do this?
Why do I have to make a call to c.log before log() method can be invoked?
My reasoning is such that since I have passed the log() method to B's
constructor, an instance
of B should invoke A's log() method.
What could I be missing in class A or B to have this working as expected?
