Ancak FastAPI olmadan `async` / `await` kullanmak istiyorsanız, <a href="https://docs.python.org/3/library/asyncio-task.html#coroutine" class="external-link" target="_blank">resmi Python belgelerini kontrol edin</a>.

### Asenkron kodun diğer biçimleri

Bu `async` ve `await` kullanimi oldukça yenidir.

* Es können **mehrere Prozesse** desselben **Programms** gleichzeitig ausgeführt werden.

Wenn Sie sich den „Task-Manager“ oder „Systemmonitor“ (oder ähnliche Tools) in Ihrem Betriebssystem ansehen, können Sie viele dieser laufenden Prozesse sehen.

* There can be **multiple processes** of the **same program** running at the same time.

If you check out the "task manager" or "system monitor" (or similar tools) in your operating system, you will be able to see many of those processes running.

/// info | 说明

只会向客户端发送 **一次响应** ，可能是一个错误响应，也可能是来自 *路由函数* 的响应。

在发送了其中一个响应之后，就无法再发送其他响应了。
