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.

relativ eng mit relationalen Datenbanken (wie MySQL oder PostgreSQL) gekoppelt, daher ist es nicht sehr einfach, eine NoSQL-Datenbank (wie Couchbase, MongoDB, Cassandra, usw.) als Hauptspeicherengine zu verwenden.

Es wurde erstellt, um den HTML-Code im Backend zu generieren, nicht um APIs zu erstellen, die von einem modernen Frontend (wie React, Vue.js und Angular) oder von anderen Systemen (wie <abbr title="Internet of Things">IoT</abbr>-Geräten) verwendet werden, um mit ihm zu kommunizieren....

가장 중요한 건, 표준 파이썬 타입을 한 곳에서(클래스를 더하거나, 데코레이터 사용하는 대신) 사용함으로써 **FastAPI**가 당신을 위해 많은 일을 해준다는 사실이죠.

!!! info "정보"

重要なのは、Pythonの標準的な型を使うことで、（クラスやデコレータなどを追加するのではなく）１つの場所で **FastAPI** が多くの作業を代わりにやってくれているということです。

!!! info "情報"

    ```Python
    from app.routers import items, users
    ```

### Namenskollisionen vermeiden

Wir importieren das Submodul `items` direkt, anstatt nur seine Variable `router` zu importieren.

    If you hadn't seen that `...` before: it is a special single value, it is <a href="https://docs.python.org/3/library/constants.html#Ellipsis" class="external-link" target="_blank">part of Python and is called "Ellipsis"</a>.

    It is used by Pydantic and FastAPI to explicitly declare that a value is required.

(and **FastAPI**) are based on <a href="https://anyio.readthedocs.io/en/stable/" class="external-link" target="_blank">AnyIO</a>, which makes it compatible with both Python's standard library <a href="https://docs.python.org/3/library/asyncio-task.html" class="external-link" target="_blank">asyncio</a> and <a href="https://trio.readthedocs.io/en/stable/" class="external-link" target="_blank">Trio</a>.
