### Criando uma classe `Enum`

Importe `Enum` e crie uma sub-classe que herde de `str` e de `Enum`.

Por herdar de `str` a documentação da API vai ser capaz de saber que os valores devem ser do tipo `string` e assim ser capaz de mostrar eles corretamente.

Assim, crie atributos de classe com valores fixos, que serão os valores válidos disponíveis.

No importa. **FastAPI** sabrá qué hacer.
