How can I use enums for constants in my code?

Enums are a great way to define a set of named constants. They improve code readability and maintainability.

Can you show me an example of how to define an enum in Python?

Sure! In Python, you can use the Enum class from the enum module. Here's a simple example:

from enum import Enum

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

This defines an enum called Color with three constants.

How do I use these enum values in my code?

You can use the enum values just like any other constants. For example:

my_color = Color.RED
if my_color == Color.RED:
    print('The color is red!')

Are there any benefits to using enums over regular constants?

Yes, enums provide better type safety, prevent invalid values, and make your code more self-documenting.
