For 2.3 or after:

     class Enumerate(object):
         def __init__(self, names):
             for number, name in enumerate(names.split()):
                 setattr(self, name, number)

To use:
     codes = Enumerate('FOO BAR BAZ')
     codes.BAZ will be 2 and so on.


if you only have 2.2, precede this with:

     from __future__ import generators

     def enumerate(iterable):
         number = 0
         for name in iterable:
             yield number, name
             number += 1




codes.BAZ
