そして、値を返すことも返さないこともできますが、値は使われません。

つまり、すでにどこかで使っている通常の依存関係（値を返すもの）を再利用でき、値は使われなくても依存関係は実行されます:

{* ../../docs_src/dependencies/tutorial006_an_py310.py hl[11,16] *}

## *path operation*のグループに対する依存関係 { #dependencies-for-a-group-of-path-operations }

後で、より大きなアプリケーションを（おそらく複数ファイルで）構造化する方法（[Bigger Applications - Multiple Files](../../tutorial/bigger-applications.md)）について読むときに、*path operation*のグループに対して単一の`dependencies`パラメータを宣言する方法を学びます。
