What is the difference between enumerations and constants in Python?

In Python, constants are variables that are meant to remain unchanged, while enumerations are a set of symbolic names bound to unique, constant values.

Can you give me an example of how to use enumerations?

Sure! You can use the enum module to create enumerations. For example:

from enum import Enum

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

This defines an enumeration for colors.

How do constants differ in implementation?

Constants in Python are typically defined using uppercase variable names, like PI = 3.14. However, Python does not enforce immutability, so it's a convention rather than a strict rule.

When should I use enumerations instead of constants?

Use enumerations when you have a fixed set of related values that you want to represent as distinct entities, which can improve code readability and maintainability.
