enum is a Python libraru that provides a module for robust enumerations in Python.
An enumeration object is created with a sequence of string arguments to the Enum() constructor:
>>> from enum import Enum
>>> Colours = Enum('red', 'blue', 'green')
>>> Weekdays = Enum('mon', 'tue', 'wed', 'thu', 'fri', 'sat', 'sun')
The return value is an immutable sequence object with a value for each of the string arguments. Each value is also available as an attribute named from the corresponding string argument:
>>> pizza_night = Weekdays
>>> shirt_colour = Colours.green
The values are constants that can be compared only with values from the same enumeration; comparison with other values will invoke Python's fallback comparisons:
>>> pizza_night == Weekdays.fri
>>> shirt_colour > Colours.red
>>> shirt_colour == "green"
Each value from an enumeration exports its sequence index as an integer, and can be coerced to a simple string matching the original arguments used to create the enumeration:
