Description:
This package 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[4]
>>> 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
True
>>> shirt_colour > Colours.red
True
>>> shirt_colour == "green"
False
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::
>>> str(pizza_night)
'fri'
>>> shirt_colour.index
