Robust enumerated data types in Python

This package provides a robust enumerated data type for Python.

An enumeration object is created with a sequence of string arguments to the Enum() function:

>>> from enum import Enum
>>> Colour = Enum('red', 'blue', 'green')
>>> Weekday = Enum('mon', 'tue', 'wed', 'thu', 'fri', 'sat', 'sun')

The return value is a new object with attributes for each of the string arguments; these attributes act as unique values within the enumeration:

>>> pixel_colour = Colour.blue

Enumeration objects are immutable, and can iterate their values. The values are constants that can be compared only with other values from the same enumeration, but can be coerced to simple strings matching the original arguments to Enum().

The design is based in part on Zoran Isailovski’s recipe, “First Class Enums in Python” in the ASPN Python Cookbook <URL:http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/413486>.
