이 경우(`Annotated`를 사용하지 않는 경우) 함수에서 기본값 `None`을 `Query()`로 바꿔야 하므로, 이제 `Query(default=None)`로 기본값을 설정해야 합니다. (최소한 FastAPI 입장에서는) 이 인자는 해당 기본값을 정의하는 것과 같은 목적을 수행합니다.

그러므로:

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

...위 코드는 기본값이 `None`인 선택적 매개변수를 만들며, 아래와 동일합니다:


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

하지만 `Query` 버전은 이것이 쿼리 매개변수임을 명시적으로 선언합니다.
