What is an enum in Python and how do I use it?

An enum, short for enumeration, is a symbolic name for a set of values. In Python, you can create enums using the enum module.

Can you show me a simple example of how to define an enum?

Sure! Here's a basic 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 using the enum member names. For example:

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

Can I iterate over the enum members?

Yes, you can iterate over the members like this:

for color in Color:
    print(color)
