Como o editor conhece os tipos de variáveis, você não obtém apenas o preenchimento automático, mas também as verificações de erro:

<img src="/img/python-types/image04.png">

Agora você sabe que precisa corrigí-lo, converta `age` em uma string com `str(age)`:

{* ../../docs_src/python_types/tutorial004_py39.py hl[2] *}

{* ../../docs_src/python_types/tutorial003_py39.py hl[1] *}

Porque el editor conoce los tipos de las variables, no solo obtienes autocompletado, también obtienes chequeo de errores:

<img src="/img/python-types/image04.png">

Ahora sabes que debes corregirlo, convertir `age` a un string con `str(age)`:

{* ../../docs_src/python_types/tutorial004_py39.py hl[2] *}

## Declaración de tipos { #declaring-types }

Y luego puedes establecer el `status_code` en ese objeto de response *temporal*.

{* ../../docs_src/response_change_status_code/tutorial001_py39.py hl[1,9,12] *}

Y luego puedes devolver cualquier objeto que necesites, como lo harías normalmente (un `dict`, un modelo de base de datos, etc.).
