### Modelo para Salida { #model-for-output }

Pero si usas el mismo modelo como salida, como aquí:

{* ../../docs_src/separate_openapi_schemas/tutorial001_py310.py hl[19] *}

...entonces, porque `description` tiene un valor por defecto, si **no devuelves nada** para ese campo, aún tendrá ese **valor por defecto**.

### Modelo para Datos de Response de Salida { #model-for-output-response-data }

### Modelo para Saída { #model-for-output }

Mas se você usar o mesmo modelo como saída, como aqui:

{* ../../docs_src/separate_openapi_schemas/tutorial001_py310.py hl[19] *}

... então, como `description` tem um valor padrão, se você **não retornar nada** para esse campo, ele ainda terá o **valor padrão**.
