    As always, in FastAPI you can combine `def` and `async def` as needed.

    If you need a refresher about when to use which, check out the section _"In a hurry?"_ in the docs about [`async` and `await`](../async.md#in-a-hurry){.internal-link target=_blank}.

9. This *path operation function* is not returning dataclasses (although it could), but a list of dictionaries with internal data.

    Source (English):

        ```mermaid
        flowchart LR
            subgraph global[global env]
                harry-1[harry v1]
            end
            subgraph stone-project[philosophers-stone project]
                stone(philosophers-stone) -->|requires| harry-1

    Wenn Sie eine Auffrischung darüber benötigen, wann welche Anwendung sinnvoll ist, lesen Sie den Abschnitt „In Eile?“ in der Dokumentation zu [`async` und `await`](../async.md#in-a-hurry){.internal-link target=_blank}.

9. Diese *Pfadoperation-Funktion* gibt keine Datenklassen zurück (obwohl dies möglich wäre), sondern eine Liste von Dictionarys mit internen Daten.

    Как и всегда в FastAPI, вы можете сочетать `def` и `async def` по необходимости.

    Если хотите освежить в памяти, когда что использовать, посмотрите раздел _"Нет времени?"_ в документации про [`async` и `await`](../async.md#in-a-hurry){.internal-link target=_blank}.

9. Эта *функция-обработчик пути* возвращает не dataclasses (хотя могла бы), а список словарей с внутренними данными.

    return {"item_id": item_id, "q": q}
```

**Hinweis**:

Wenn Sie das nicht kennen, schauen Sie sich den Abschnitt _„In Eile?“_ über <a href="https://fastapi.tiangolo.com/de/async/#in-a-hurry" target="_blank">`async` und `await` in der Dokumentation</a> an.
