### `Response` を返す

[レスポンスを直接返す](response-directly.md){.internal-link target=_blank}で見たように、レスポンスを直接返すことで、*path operation* の中でレスポンスをオーバーライドできます。

上記と同じ例において、 `HTMLResponse` を返すと、このようになります:

```Python hl_lines="2  7  19"
{!../../docs_src/custom_response/tutorial003.py!}
```

/// warning | "注意"

*path operation関数* から直接返される `Response` は、OpenAPIにドキュメントされず (例えば、 `Content-Type` がドキュメントされない) 、自動的な対話的ドキュメントからも閲覧できません。

    # via -r ci/official/requirements_updater/requirements.in
tblib==2.0.0 \

O mesmo exemplo de antes, retornando uma `HTMLResponse`, poderia parecer com:

```Python hl_lines="2  7  19"
{!../../docs_src/custom_response/tutorial003.py!}
```
