Es handelt sich schlicht um eine Standard-Funktion, die Parameter empfangen kann.

Es kann sich um eine `async def`- oder normale `def`-Funktion handeln. **FastAPI** weiß, wie damit zu verfahren ist.

In diesem Fall schreibt die Taskfunktion in eine Datei (den Versand einer E-Mail simulierend).

Und da der Schreibvorgang nicht `async` und `await` verwendet, definieren wir die Funktion mit normalem `def`:

이것은 파이썬 함수입니다.

URL "`/`"에 대한 `GET` 작동을 사용하는 요청을 받을 때마다 **FastAPI**에 의해 호출됩니다.

위의 예시에서 이 함수는 `async`(비동기) 함수입니다.

---

`async def`을 이용하는 대신 일반 함수로 정의할 수 있습니다:

차이점을 모르겠다면 [Async: *"바쁘신 경우"*](../async.md#in-a-hurry)를 확인하세요.
