## Предопределенные значения

Что если нам нужно заранее определить допустимые *параметры пути*, которые *операция пути* может принимать? В таком случае можно использовать стандартное перечисление <abbr title="Enumeration">`Enum`</abbr> Python.

### Создание класса `Enum`

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