Today's topic is enum module. PEP 435 introduced the enum module in Python 3.4, providing support for enumerations in Python.

Enumerations are sets of symbolic names (members) bound to unique, constant values. They are used to make code more descriptive and readable. Enums help to address specific variant or case in your code, without actually relying on the value corresponding to that variant.

Quiz

Which one of these code samples correctly demonstrates the use of Enums in Python?

Sample 1

from enum import Enum

class Color(Enum):
    RED = 1
    GREEN = 2
    BLUE = 3

favorite_color = Color.RED
print(favorite_color.name, favorite_color.value)

Sample 2

class Color:
    RED = 1
    GREEN = 2
    BLUE = 3

favorite_color = Color.RED
print(favorite_color.name, favorite_color.value)

Post your answer in the comments – is it 0 for the first sample or 1 for the second! As usual, the correct answer will be explained in the comment.
