When I wrote earlier, I wondered about the need for initialization.

With Version 2, both __new__ and __init__ were required, not in the 
example below, using version 3.2:
#!/usr/bin/env python

class A():

   def ringA(self):
     print ('aaa')

   def ringB(self):
     print('bbb')

class B(A):
   def __init__(self:)
   def ringB(self):
     print('BBB')

a= A()
b= B()
b.ringB()
b.ringA()
b.__class__.mro()[0].ringB(22)   #  22 is used for the ringB attribute
                                  #  Trial and error shows that any
                                  #  non-Null,including None for the
                                  #  argument gives the same result
z= 1
def main():
     pass

if __name__ == '__main__':
     main()
