Enumerations

There are common programming features that are found in many programming languages regardless of the dominant programming paradigm. One such feature is enumerated types that have a finite number of named values. They are especially useful for encoding a closed set of values for variables or function arguments.

One of the special handy types found in the Python Standard Library is the Enum class from the enum module. This is a base class that allows you to define symbolic enumerations, similar in concept to the enumerated types found in many other programming languages (C, C++, C#, Java, and many more) that are often denoted with the enum keyword.

In order to define your own enumeration in Python, you will need to subclass the Enum class and define all enumeration members as class attributes. The following is an example of a simple Python enum:

from enum import Enum
class Weekday(Enum):
    MONDAY = 0
    TUESDAY = 1
    WEDNESDAY = 2
    THURSDAY = 3
    FRIDAY...
