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.

O programa de linha de comando chamado `fastapi` é o **FastAPI CLI**.

O FastAPI CLI recebe o caminho para o seu programa Python (por exemplo, `main.py`), detecta automaticamente a instância de `FastAPI` (comumente nomeada `app`), determina a forma correta de importação e então a serve.

Para produção, você usaria `fastapi run`. 🚀
