Sem ter que saber de antemão quais são os nomes de campos/atributos válidos (como seria o caso dos modelos Pydantic).

Isso seria útil se você deseja receber chaves que ainda não conhece.

---

Outro caso útil é quando você deseja ter chaves de outro tipo, por exemplo, `int`.

É isso que vamos ver aqui.

Neste caso, você aceitaria qualquer `dict`, desde que tenha chaves` int` com valores `float`:

Ce n'est pas la même chose que de déclarer des valeurs par défaut, ce qui serait :

```Python
    first_name="john", last_name="doe"
```

C'est différent.

Nous utilisons des deux-points (`:`), pas des signes égal (`=`).

Et ajouter des annotations de type ne change normalement pas ce qui se passe par rapport à ce qui se passerait sans elles.
