8. Notice that this *path operation function* uses regular `def` instead of `async def`.

    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}.

### コード内での`HTTPException`の発生

`HTTPException`は通常のPythonの例外であり、APIに関連するデータを追加したものです。

Pythonの例外なので、`return`ではなく、`raise`です。

これはまた、*path operation関数*の内部で呼び出しているユーティリティ関数の内部から`HTTPException`を発生させた場合、*path operation関数*の残りのコードは実行されず、そのリクエストを直ちに終了させ、`HTTPException`からのHTTPエラーをクライアントに送信することを意味します。

値を返す`return`よりも例外を発生させることの利点は、「依存関係とセキュリティ」のセクションでより明確になります。

# Return a Response Directly { #return-a-response-directly }

When you create a **FastAPI** *path operation* you can normally return any data from it: a `dict`, a `list`, a Pydantic model, a database model, etc.

By default, **FastAPI** would automatically convert that return value to JSON using the `jsonable_encoder` explained in [JSON Compatible Encoder](../tutorial/encoder.md){.internal-link target=_blank}.
