No, that's still wrong. The OP talks abut maps having names, not
rules having names. Unless a Rule is-a Map, which sounds unlikely,
Rule should not be inheriting from Map in the first place.

You'll need to keep a reference to the Map on each Rule instance. So
instead of self.mapName you'll have self.map.mapName. Your Rule class
should probably look something like this:
class Rule(object):
def __init__(self, map, number):
self.map = map
self.number = number
And then when you construct it you'll need to tell it what map it belongs to:
rule = Rule(map, 1)
