I guess you could fake this (a bit) in Python by:

class Foo(Bar):
   super = Bar
   def __init__(self):
      self.super.__init__(self)
      # do something
   def doit(self):
      self.super.doit(self)
      # do the polymorphic thing

That's the usual way, it does mean that if you change the 
superclass you have to change all the calls to it, whereas 
the self.super technique means only one change - otherwise 
there's no advantage.
