How can I use enums as constants in Python?

You can use the enum module in Python to create enumerations, which are a set of symbolic names bound to unique, constant values.

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 constants.

How do I access the values of the enum?

You can access the values using the enum name. For example, Color.RED will give you Color.RED, and you can get its value with Color.RED.value, which will return 1.

Can I iterate over the enum members?

Yes, you can iterate over the enum members like this:

for color in Color:
    print(color)

This will print each member of the Color enum.
