위 예제는 필요한 모든 부분을 보여주지만, 아직은 그다지 유용하지 않습니다. `item`을 그냥 직접 반환했어도 **FastAPI**가 기본으로 이를 `JSONResponse`에 넣고 `dict`로 변환하는 등의 작업을 모두 수행해 주었을 것이기 때문입니다.

이제, 이를 사용해 사용자 정의 응답을 반환하는 방법을 알아보겠습니다.

예를 들어 [XML](https://en.wikipedia.org/wiki/XML) 응답을 반환하고 싶다고 가정해 보겠습니다.

XML 내용을 문자열에 넣고, 이를 `Response`에 넣어 반환할 수 있습니다:

{* ../../docs_src/response_directly/tutorial002_py310.py hl[1,18] *}
