#### "Schéma" d'API

Ici, <a href="https://github.com/OAI/OpenAPI-Specification" class="external-link" target="_blank">OpenAPI</a> est une spécification qui dicte comment définir le schéma de votre API.

Le schéma inclut les chemins de votre API, les paramètres potentiels de chaque chemin, etc.

#### "Schéma" de données

Comme nous devons remplacer la valeur par défaut `None` dans la fonction par `Query()`, nous pouvons maintenant définir la valeur par défaut avec le paramètre `Query(default=None)`, il sert le même objectif qui est de définir cette valeur par défaut.

Donc :

```Python
q: Union[str, None] = Query(default=None)
```

... rend le paramètre optionnel, et est donc équivalent à :

---

Si simplemente no lo sabes, usa `def` normal.

---

**Nota**: Puedes mezclar `def` y `async def` en tus *path operation functions* tanto como necesites y definir cada una utilizando la mejor opción para ti. FastAPI hará lo correcto con ellas.

De todos modos, en cualquiera de los casos anteriores, FastAPI seguirá funcionando de forma asíncrona y será extremadamente rápido.
