Backward chaining for __init__?

[Courageous]

I recently wrote a test program with a Parent class
and a Derived class, each one implementing __init__.
To my surprise and chagrine, only the Child's __init__
method was called. Worse, I can't figure out a way to
call the method (or methods, in the case of multiple
inheritance) in the Parent.

How does one go about implementing backward chaining
for constructor's in Python?
