You can use reflection to do this. Perhaps a constructor that goes
through your class dict (dir(self)) and builds an int->string mapping
property based on the value and name of the attributes (perhaps just
the ones whose type is int). To get the exact same result as your code
above you can capitalize the first letter of the attribute name, and
lowercase the rest.
