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.

Por exemplo, ele não recebe objetos `datetime`, pois estes objetos não são compatíveis com JSON.

Então, um objeto `datetime` teria que ser convertido em um `str` contendo os dados no <a href="https://en.wikipedia.org/wiki/ISO_8601" class="external-link" target="_blank">formato ISO</a>.

Da mesma forma, este banco de dados não receberia um modelo Pydantic (um objeto com atributos), apenas um `dict`.
