### Создание класса `Enum` { #create-an-enum-class }

Импортируйте `Enum` и создайте подкласс, который наследуется от `str` и `Enum`.

Мы наследуемся от `str`, чтобы документация API могла понять, что значения должны быть типа `string` и отображалась правильно.

Затем создайте атрибуты класса с фиксированными допустимыми значениями:
