`from starlette import status`を使用することもできます。

**FastAPI** は開発者の利便性を考慮して、`fastapi.status`と同じ`starlette.status`を提供しています。しかし、これはStarletteから直接提供されています。

## タグ { #tags }

`tags`パラメータを`str`の`list`（通常は１つの`str`）と一緒に渡すと、*path operation*にタグを追加できます:

{* ../../docs_src/path_operation_configuration/tutorial002_py310.py hl[15,20,25] *}

これらはOpenAPIスキーマに追加され、自動ドキュメントのインターフェースで使用されます:
