1. 이것이 제너레이터 함수입니다. `yield` 문을 포함하고 있으므로 "제너레이터 함수"입니다.
2. `with` 블록을 사용함으로써, 제너레이터 함수가 완료된 후 파일과 같은 객체가 닫히도록 합니다. 즉, 응답 전송이 끝난 후 닫힙니다.
3. 이 `yield from`은 함수가 `file_like`라는 객체를 반복(iterate)하도록 합니다. 반복된 각 부분은 이 제너레이터 함수(`iterfile`)에서 생성된 것처럼 `yield` 됩니다.

    이렇게 하면 "생성(generating)" 작업을 내부적으로 다른 무언가에 위임하는 제너레이터 함수가 됩니다.

2. By using a `with` block, we make sure that the file-like object is closed after the generator function is done. So, after it finishes sending the response.
3. This `yield from` tells the function to iterate over that thing named `file_like`. And then, for each part iterated, yield that part as coming from this generator function (`iterfile`).

    So, it is a generator function that transfers the "generating" work to something else internally.

3. Dieses `yield from` weist die Funktion an, über das Ding namens `file_like` zu iterieren. Und dann für jeden iterierten Teil, diesen Teil so zurückzugeben, als wenn er aus dieser Generatorfunktion (`iterfile`) stammen würde.
