## Response description { #response-description }

You can specify the response description with the parameter `response_description`:

{* ../../docs_src/path_operation_configuration/tutorial005_py310.py hl[19] *}

/// info

We can instead create an input model with the plaintext password and an output model without it:

{* ../../docs_src/response_model/tutorial003_py310.py hl[9,11,16] *}

Here, even though our *path operation function* is returning the same input user that contains the password:

{* ../../docs_src/response_model/tutorial003_py310.py hl[24] *}

...we declared the `response_model` to be our model `UserOut`, that doesn't include the password:

{* ../../docs_src/response_model/tutorial003_py310.py hl[9,11,16] *}

Aqui, embora nossa *função de operação de rota* esteja retornando o mesmo usuário de entrada que contém a senha:

{* ../../docs_src/response_model/tutorial003_py310.py hl[24] *}

...declaramos o `response_model` como nosso modelo `UserOut`, que não inclui a senha:

{* ../../docs_src/response_model/tutorial003_py310.py hl[22] *}

{* ../../docs_src/path_operation_configuration/tutorial004_py310.py hl[17:25] *}

## Descripción del Response { #response-description }

Puedes especificar la descripción del response con el parámetro `response_description`:

{* ../../docs_src/path_operation_configuration/tutorial005_py310.py hl[19] *}

/// info | Información

{* ../../docs_src/path_operation_configuration/tutorial004_py310.py hl[17:25] *}

## Descrição da resposta { #response-description }

Você pode especificar a descrição da resposta com o parâmetro `response_description`:

{* ../../docs_src/path_operation_configuration/tutorial005_py310.py hl[19] *}

/// info | Informação

{* ../../docs_src/response_model/tutorial003_py310.py hl[9,11,16] *}

Obwohl unsere *Pfadoperation-Funktion* hier denselben `user` von der Eingabe zurückgibt, der das Passwort enthält:

{* ../../docs_src/response_model/tutorial003_py310.py hl[24] *}

... haben wir deklariert, dass `response_model` das Modell `UserOut` ist, welches das Passwort nicht enthält:

{* ../../docs_src/response_model/tutorial003_py310.py hl[9,11,16] *}

Тут, навіть якщо *функція операції шляху* повертає об'єкт користувача, який містить пароль:

{* ../../docs_src/response_model/tutorial003_py310.py hl[24] *}

...ми оголосили `response_model` як нашу модель `UserOut`, яка не містить пароля:

{* ../../docs_src/response_model/tutorial003_py310.py hl[22] *}

{* ../../docs_src/response_model/tutorial003_py310.py hl[9,11,16] *}

Здесь, хотя *функция-обработчик пути* возвращает тот же входной объект пользователя, содержащий пароль:

{* ../../docs_src/response_model/tutorial003_py310.py hl[24] *}

...мы объявили `response_model` как модель `UserOut`, в которой нет пароля:

{* ../../docs_src/response_model/tutorial003_py310.py hl[22] *}

Primero, necesitas importar `BaseModel` de `pydantic`:

{* ../../docs_src/body/tutorial001_py310.py hl[2] *}

## Crea tu modelo de datos { #create-your-data-model }

Luego, declaras tu modelo de datos como una clase que hereda de `BaseModel`.

Usa tipos estándar de Python para todos los atributos:

{* ../../docs_src/body/tutorial001_py310.py hl[5:9] *}

## Optionale Parameter { #optional-parameters }

Auf die gleiche Weise können Sie optionale Query-Parameter deklarieren, indem Sie deren Defaultwert auf `None` setzen:

{* ../../docs_src/query_params/tutorial002_py310.py hl[7] *}

In diesem Fall wird der Funktionsparameter `q` optional und standardmäßig `None` sein.
