여기서, `shutdown` 이벤트 핸들러 함수는 `"Application shutdown"`이라는 텍스트를 `log.txt` 파일에 기록합니다.

/// info | 정보

`open()` 함수에서 `mode="a"`는 "추가"를 의미하므로, 파일에 있는 기존 내용은 덮어쓰지 않고 새로운 줄이 추가됩니다.

/// tip | 팁

이 경우, 우리는 표준 파이썬 `open()` 함수를 사용하여 파일과 상호작용하고 있습니다.

따라서 I/O(입출력) 작업이 포함되어 있어 디스크에 기록되는 것을 "기다리는" 과정이 필요합니다.

하지만 `open()`은 `async`와 `await`를 사용하지 않습니다.

그래서 우리는 이벤트 핸들러 함수를 `async def` 대신 일반 `def`로 선언합니다.
