Vous déclarez la forme de la donnée avec des classes et des attributs.

Chaque attribut possède un type.

Puis vous créez une instance de cette classe avec certaines valeurs et **Pydantic** validera les valeurs, les convertira dans le type adéquat (si c'est nécessaire et possible) et vous donnera un objet avec toute la donnée.

Ainsi, votre éditeur vous offrira un support adapté pour l'objet résultant.

Você pode retornar um `dict`, `list` e valores singulares como `str`, `int`, etc.

Você também pode devolver modelos Pydantic (você verá mais sobre isso mais tarde).

Existem muitos outros objetos e modelos que serão convertidos automaticamente para JSON (incluindo ORMs, etc). Tente usar seus favoritos, é altamente provável que já sejam compatíveis.

## Recapitulando

* Importe `FastAPI`.
* Crie uma instância do `app`.
