Fíjate que `Field` se importa directamente desde `pydantic`, no desde `fastapi` como el resto (`Query`, `Path`, `Body`, etc).

## Declarar atributos del modelo { #declare-model-attributes }

Después puedes utilizar `Field` con los atributos del modelo:

{* ../../docs_src/body_fields/tutorial001_an_py310.py hl[11:14] *}

`Field` funciona de la misma manera que `Query`, `Path` y `Body`, tiene todos los mismos parámetros, etc.

## Импорт `Cookie` { #import-cookie }

Сначала импортируйте `Cookie`:

{* ../../docs_src/cookie_params/tutorial001_an_py310.py hl[3] *}

## Объявление параметров `Cookie` { #declare-cookie-parameters }

Затем объявляйте параметры cookie, используя ту же структуру, что и с `Path` и `Query`.

Вы можете задать значение по умолчанию, а также все дополнительные параметры валидации или аннотации:

## Объявление атрибутов модели { #declare-model-attributes }

Вы можете использовать функцию `Field` с атрибутами модели:

Para isso, você pode declarar que `None` é um tipo válido, mas simplesmente não declarar um valor padrão:
