Do-It-Yourself Enumeration in Python

Python Enum

class enum(object):
    def __init__(self, *names):
        for number, name in enumerate(names):
            setattr(self, name, number)

Example:

Month = enum(
    "January",
    "Febuary",
    "March",
     ...
    "December",
    )

print Month.January
print Month.March
print Month.December

Output:
0
3
11
