## `Field` de argumentos adicionais

Ao usar `Field ()` com modelos Pydantic, você também pode declarar informações extras para o **JSON Schema** passando quaisquer outros argumentos arbitrários para a função.

## Дополнительные аргументы поля `Field`

При использовании `Field()` с моделями Pydantic, вы также можете объявлять дополнительную информацию для **JSON Schema**, передавая любые другие произвольные аргументы в функцию.
