## Coroutinen { #coroutines }

**Coroutine** ist nur ein schicker Begriff für dasjenige, was von einer `async def`-Funktion zurückgegeben wird. Python weiß, dass es so etwas wie eine Funktion ist, die es starten kann und die irgendwann endet, aber auch dass sie pausiert ⏸ werden kann, wann immer darin ein `await` steht.

Sie übergeben `Depends` nur einen einzigen Parameter.

Dieser Parameter muss so etwas wie eine Funktion sein.

Sie **rufen diese nicht direkt auf** (fügen Sie am Ende keine Klammern hinzu), sondern übergeben sie einfach als Parameter an `Depends()`.

Und diese Funktion akzeptiert Parameter auf die gleiche Weise wie *Pfadoperation-Funktionen*.

/// tip | Tipp

Sie wird direkt in FastAPI importiert/inkludiert, sodass Sie sie von `fastapi` importieren können und vermeiden, versehentlich das alternative `BackgroundTask` (ohne das `s` am Ende) von `starlette.background` zu importieren.
