可能であれば`Annotated`版を使うことを推奨します。

* Add translation to Spanish for [Concurrency and async / await - Concurrencia y async / await](https://fastapi.tiangolo.com/es/async/). PR [#1290](https://github.com/tiangolo/fastapi/pull/1290) by [@alvaropernas](https://github.com/alvaropernas).

    github enables querying for PR and also create issue using rest endpoint

これは、Pythonの関数です。

この関数は、`GET`オペレーションを使ったURL「`/`」へのリクエストを受け取るたびに**FastAPI**によって呼び出されます。

この場合、この関数は`async`関数です。

---

`async def`の代わりに通常の関数として定義することもできます:

{* ../../docs_src/first_steps/tutorial003_py310.py hl[7] *}

/// note | 備考

違いが分からない場合は、[Async: *「急いでいますか？」*](../async.md#in-a-hurry)を確認してください。
