También vuelve a declarar `id: int`. Al hacer esto, estamos haciendo un **contrato** con los clientes de la API, para que siempre puedan esperar que el `id` esté allí y sea un `int` (nunca será `None`).

Vous pouvez déclarer le type d'un paramètre de chemin dans la fonction, en utilisant les annotations de type Python :


{* ../../docs_src/path_params/tutorial002.py hl[7] *}

Ici, `item_id` est déclaré comme `int`.

/// check | vérifier

Ceci vous permettra d'obtenir des fonctionnalités de l'éditeur dans votre fonction, telles
que des vérifications d'erreur, de l'auto-complétion, etc.
