What is the purpose of the IntegerChoices class in development?

The IntegerChoices class in Python, most commonly used in Django, is used to define a set of constants with integer values that can be used in models for fields with a limited set of options (choices). This improves code readability and simplifies working with value selection, providing convenient access to names and values.

Example of usage:

from django.db import models

class Status(models.IntegerChoices):
    DRAFT = 1, 'Draft'
    PUBLISHED = 2, 'Published'
    ARCHIVED = 3, 'Archived'

class Article(models.Model):
    status = models.IntegerField(choices=Status.choices, default=Status.DRAFT)

Here, Status is a subclass of IntegerChoices, where each status corresponds to an integer value and a human-readable description.
