## Déclarer des champs de liste { #list-fields }

Vous pouvez définir un attribut comme étant un sous-type. Par exemple, une `list` Python :

{* ../../docs_src/body_nested_models/tutorial001_py310.py hl[12] *}

Cela fera de `tags` une liste, bien que le type des éléments de la liste ne soit pas déclaré.

## Champs de liste avec paramètre de type { #list-fields-with-type-parameter }

## Proibir Campos Extras de Formulários { #forbid-extra-form-fields }

Em alguns casos de uso especiais (provavelmente não muito comum), você pode desejar **restringir** os campos do formulário para aceitar apenas os declarados no modelo Pydantic. E **proibir** qualquer campo **extra**.
