What are enums in Python and how do I use them?

Enums, or enumerations, are a way to define a set of named values in Python. They help make your code more readable and maintainable.

Can you show me an example of how to create an enum?

Sure! You can create an enum using 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 members.

How do I access the values of the enum?

You can access the values of the enum by using the member names. For example:

print(Color.RED)
print(Color.GREEN.value)

This will output Color.RED and 2 respectively.

Are there any advantages to using enums?

Yes, enums provide better code clarity, prevent invalid values, and allow for easy iteration over the defined values.
