Todo **FastAPI** está basado en estos type hints, lo que le da muchas ventajas y beneficios.

Pero, así nunca uses **FastAPI** te beneficiarás de aprender un poco sobre los type hints.

!!! note "Nota"
    Si eres un experto en Python y ya lo sabes todo sobre los type hints, salta al siguiente capítulo.

## Mais motivação

Marque esta função, ela já possui type hints:

```

Como o editor conhece os tipos de variáveis, você não apenas obtém a conclusão, mas também as verificações de erro:
