Perceba que isso significa que "`one_person` é uma **instância** da classe `Person`".

Isso não significa que "`one_person` é a **classe** chamada `Person`".

## Modelos Pydantic

O <a href="https://docs.pydantic.dev/" class="external-link" target="_blank">Pydantic</a> é uma biblioteca Python para executar a validação de dados.

Você declara a "forma" dos dados como classes com atributos.

E cada atributo tem um tipo.

### 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.
