## 매개변수 사용하지 않게 하기

이제는 더이상 이 매개변수를 마음에 들어하지 않는다고 가정해 봅시다.

이 매개변수를 사용하는 클라이언트가 있기 때문에 한동안은 남겨둬야 하지만, <abbr title="구식이며, 사용하지 않는 것을 추천">사용되지 않는다(deprecated)</abbr>고 확실하게 문서에서 보여주고 싶습니다.

그렇다면 `deprecated=True` 매개변수를 `Query`로 전달합니다:

```Python hl_lines="18"
{!../../docs_src/query_params_str_validations/tutorial010.py!}
```

문서가 아래와 같이 보일겁니다:
