Nous avions cette annotation de type :

```Python
q: str | None = None
```

Ce que nous allons faire, c’est l’englober avec `Annotated`, de sorte que cela devienne :

```Python
q: Annotated[str | None] = None
```

Les deux versions signifient la même chose, `q` est un paramètre qui peut être une `str` ou `None`, et par défaut, c’est `None`.

Passons maintenant aux choses amusantes. 🎉
