## Query-Parameter Typkonvertierung { #query-parameter-type-conversion }

Sie können auch `bool`-Typen deklarieren, und sie werden konvertiert:

FastAPI는 `q`가 `= None`이므로 선택적이라는 것을 인지합니다.

`Union[str, None]`에 있는 `Union`은 FastAPI(FastAPI는 `str` 부분만 사용합니다)가 사용하는게 아니지만, `Union[str, None]`은 편집기에게 코드에서 오류를 찾아낼 수 있게 도와줍니다.

## 쿼리 매개변수 형변환

`bool` 형으로 선언할 수도 있고, 아래처럼 변환됩니다:

{* ../../docs_src/query_params/tutorial003.py hl[9] *}

이 경우, 아래로 이동하면:

```

```

또는
