또한 `response`가 생성된 후, 반환하기 전에 코드를 추가할 수도 있습니다.

예를 들어, 요청을 처리하고 응답을 생성하는 데 걸린 시간을 초 단위로 담는 사용자 정의 헤더 `X-Process-Time`을 추가할 수 있습니다:

{* ../../docs_src/middleware/tutorial001_py310.py hl[10,12:13] *}

/// tip | 팁

여기서는 이러한 사용 사례에서 더 정확할 수 있기 때문에 `time.time()` 대신 [`time.perf_counter()`](https://docs.python.org/3/library/time.html#time.perf_counter)를 사용합니다. 🤓
