Python wird sich beschweren, wenn Sie einen Wert mit einem „Default“ vor einem Wert ohne „Default“ setzen.

Aber Sie können die Reihenfolge ändern und den Wert ohne Default (den Query-Parameter `q`) zuerst setzen.

Für **FastAPI** spielt es keine Rolle. Es erkennt die Parameter anhand ihrer Namen, Typen und Default-Deklarationen (`Query`, `Path`, usw.), es kümmert sich nicht um die Reihenfolge.

Entonces:

```Python
q: str | None = Query(default=None)
```

...hace que el parámetro sea opcional, con un valor por defecto de `None`, lo mismo que:
