Is there a better way to get a named series of constants (enumeration) in Python? [duplicate]

Answer 1

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
