What are the differences between enum and constant in Python?

Can you explain the differences between enums and constants in Python?

Sure! In Python, constants are typically defined using uppercase variable names and are meant to remain unchanged. Enums, on the other hand, are a special type of class that allows you to define a set of named values.

What are the benefits of using enums over constants?

Enums provide better readability and organization, as they group related values together. They also prevent invalid values since you can only use the defined enum members.

Can you give me an example of how to define an enum in Python?

Absolutely! You can define an enum using the Enum class from the enum module. For example:

from enum import Enum

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

Are there any performance differences between using enums and constants?

Generally, enums may have a slight overhead due to their class structure, but the difference is negligible for most applications. The choice should be based on clarity and maintainability.
