## Vous êtes pressés ? { #in-a-hurry }

<abbr title="too long; didn't read - trop long ; pas lu"><strong>TL;DR :</strong></abbr>

Si vous utilisez des bibliothèques tierces qui nécessitent d'être appelées avec `await`, telles que :

```Python

/// note | Примечание

Если вы не знаете, в чём разница, посмотрите [Асинхронность: *"Нет времени?"*](../async.md#in-a-hurry).

### Шаг 5: верните содержимое { #step-5-return-the-content }

{* ../../docs_src/first_steps/tutorial001_py310.py hl[8] *}

Вы можете вернуть `dict`, `list`, отдельные значения `str`, `int` и т.д.

/// note | Hinweis

Wenn Sie den Unterschied nicht kennen, lesen Sie [Async: *„In Eile?“*](../async.md#in-a-hurry).

### Schritt 5: den Inhalt zurückgeben { #step-5-return-the-content }

Detalles sobre la sintaxis `async def` para *path operation functions* y algunos antecedentes sobre el código asíncrono, la concurrencia y el paralelismo.

## ¿Con prisa? { #in-a-hurry }

<abbr title="too long; didn't read - demasiado largo; no lo leí"><strong>TL;DR:</strong></abbr>

Si estás usando paquetes de terceros que te dicen que los llames con `await`, como:

```Python

@app.get("/items/{item_id}")
async def read_item(item_id: int, q: str | None = None):
    return {"item_id": item_id, "q": q}
```

**注**:

わからない場合は、_「In a hurry?」_ セクションの [ドキュメントの `async` と `await`](https://fastapi.tiangolo.com/ja/async/#in-a-hurry) を確認してください。
