This is probably the best advice for this situation.

There are a lot of times when having an enumeration is nice, and a class
would be overkill. I forget where I've seen the idiom, and I certainly
didn't make it up, but a really nice way to make an enum is to do
something like:
one, two, three = range(3)
print one, two, three
Works every time. If you forget to increase the range size when you add
a new value, you will get a runtime error because the tuple unpack won't work.
