What are some examples of enumerations in Python?

In Python, enumerations can be created using the enum module. For example, you can define days of the week like this:

from enum import Enum

class Day(Enum):
    MONDAY = 1
    TUESDAY = 2
    WEDNESDAY = 3
    THURSDAY = 4
    FRIDAY = 5
    SATURDAY = 6
    SUNDAY = 7

This allows you to use Day.MONDAY instead of just a number.

Can you show me how to use this enumeration in a function?

Sure! Here's an example function that takes a Day enumeration as an argument:

def is_weekend(day):
    return day in (Day.SATURDAY, Day.SUNDAY)

You can call it like this:

print(is_weekend(Day.SATURDAY))  # Output: True
print(is_weekend(Day.MONDAY))    # Output: False

What are the benefits of using enumerations?

Enumerations improve code readability and maintainability. They provide meaningful names to sets of related constants, reducing errors and making the code easier to understand.
