What are the benefits of using enumerations in Python?

Enumerations in Python provide a way to define a set of named values, improving code readability and maintainability.

Can you give me an example of how to use enumerations?

Sure! You can use the Enum class from the enum module. For example:

from enum import Enum

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

This defines an enumeration for colors.

What are some advantages over using constants?

Enumerations provide type safety, meaning you can't accidentally assign a value that isn't part of the enumeration. They also allow for better organization of related constants.

Are there any performance drawbacks?

Generally, the performance impact is minimal. However, using enumerations may introduce slight overhead compared to simple constants, but the benefits often outweigh this.
