Starlette (ve **FastAPI**) [AnyIO](https://anyio.readthedocs.io/en/stable/) üzerine kuruludur; bu sayede Python standart kütüphanesindeki [asyncio](https://docs.python.org/3/library/asyncio-task.html) ve [Trio](https://trio.readthedocs.io/en/stable/) ile uyumludur.

Özellikle, kendi kodunuzda daha gelişmiş desenler gerektiren ileri seviye eşzamanlılık kullanım senaryoları için doğrudan [AnyIO](https://anyio.readthedocs.io/en/stable/) kullanabilirsiniz.

Starlette (et **FastAPI**) s’appuie sur [AnyIO](https://anyio.readthedocs.io/en/stable/), ce qui le rend compatible à la fois avec la bibliothèque standard [asyncio](https://docs.python.org/3/library/asyncio-task.html) de Python et avec [Trio](https://trio.readthedocs.io/en/stable/).

Starlette (y **FastAPI**) están basados en [AnyIO](https://anyio.readthedocs.io/en/stable/), lo que lo hace compatible tanto con el [asyncio](https://docs.python.org/3/library/asyncio-task.html) del paquete estándar de Python como con [Trio](https://trio.readthedocs.io/en/stable/).

Starlette (und **FastAPI**) basieren auf [AnyIO](https://anyio.readthedocs.io/en/stable/), was bedeutet, dass es sowohl kompatibel mit der Python-Standardbibliothek [asyncio](https://docs.python.org/3/library/asyncio-task.html) als auch mit [Trio](https://trio.readthedocs.io/en/stable/) ist.

Comme ce petit exemple n'a besoin d'aucune instruction `await`, nous ajoutons un `await anyio.sleep(0)` pour donner une chance à la boucle d'événements de gérer l'annulation.

Cela serait encore plus important avec des flux volumineux ou infinis.

///

/// tip | Astuce

Da dieses kleine Beispiel keine `await`-Anweisungen benötigt, fügen wir ein `await anyio.sleep(0)` hinzu, um dem Event Loop die Chance zu geben, den Abbruch zu verarbeiten.

Dies wäre bei großen oder unendlichen Streams noch wichtiger.

///

/// tip | Tipp

Since this small example does not need any `await` statements, we add an `await anyio.sleep(0)` to give the event loop a chance to handle cancellation.

This would be even more important with large or infinite streams.

///

/// tip

Bu küçük örneğin `await` ifadesine ihtiyacı olmadığı için, event loop’un iptali ele alabilmesi adına `await anyio.sleep(0)` ekliyoruz.

Büyük veya sonsuz akışlarda bu daha da önemlidir.
