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.

#### 파일과 같은 객체를 사용한 `StreamingResponse`

파일과 같은 객체(예: `open()`으로 반환된 객체)가 있는 경우, 해당 파일과 같은 객체를 반복(iterate)하는 제너레이터 함수를 만들 수 있습니다.

이 방식으로, 파일 전체를 메모리에 먼저 읽어들일 필요 없이, 제너레이터 함수를 `StreamingResponse`에 전달하여 반환할 수 있습니다.

이 방식은 클라우드 스토리지, 비디오 처리 등의 다양한 라이브러리와 함께 사용할 수 있습니다.
