3. A dataclass `Author` inclui uma lista de dataclasses `Item`.

4. A dataclass `Author` é usada como o parâmetro `response_model`.

5. Você pode usar outras anotações de tipo padrão com dataclasses como o corpo da requisição.

    Neste caso, é uma lista de dataclasses `Item`.

6. Aqui estamos retornando um dicionário que contém `items`, que é uma lista de dataclasses.

### Modelo para Entrada y Salida en la Documentación

Y si revisas todos los esquemas disponibles (JSON Schemas) en OpenAPI, verás que hay dos, uno `Item-Input` y uno `Item-Output`.

Para `Item-Input`, `description` **no es requerido**, no tiene un asterisco rojo.

Pero para `Item-Output`, `description` **es requerido**, tiene un asterisco rojo.
