How do I define enumerations in Python?

You can define enumerations in Python using the enum module. Here's a simple example:

from enum import Enum

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

This creates an enumeration called Color with three members.

What are the benefits of using enumerations?

Enumerations provide a way to define a set of named values, which can improve code readability and maintainability. They also help prevent errors by restricting values to predefined constants.

Can I iterate over the members of an enumeration?

Yes, you can iterate over the members of an enumeration using a simple loop. For example:

for color in Color:
    print(color)

Are there any built-in methods for enumerations?

Yes, enumerations come with several built-in methods, such as name and value, which allow you to access the name and value of the enumeration members.
