Can a child access parent attributes if that child added post-hoc as an attribute to the parent?

This means that rules will never have a name. I think you need
      def __init__(self, name='', number=None):
          Map.__init__(self, name)
          self.number = number

I not sure what you mean by the above. Can you provide an example of what you want
to occur and the output for it?
