### Crea una clase `Enum`

Importa `Enum` y crea una sub-clase que herede desde `str` y desde `Enum`.

Al heredar desde `str` la documentación de la API podrá saber que los valores deben ser de tipo `string` y podrá mostrarlos correctamente.

Luego crea atributos de clase con valores fijos, que serán los valores disponibles válidos:

```Python hl_lines="1  6-9"
