つまり、Pythonが環境変数から読み取る**あらゆる値**は **`str`型となり**、他の型への変換やバリデーションはコード内で行う必要があります。

環境変数を使用して**アプリケーション設定**を管理する方法については、[高度なユーザーガイド - Settings and Environment Variables](./advanced/settings.md){.internal-link target=_blank}で詳しく学べます。

## `PATH`環境変数

**`PATH`**という**特別な**環境変数があります。この環境変数は、OS（Linux、macOS、Windows）が実行するプログラムを発見するために使用されます。

Mit **FastAPI** ist das sehr einfach (dank Starlette), schauen Sie sich die Dokumentation an: [Testen](../tutorial/testing.md){.internal-link target=_blank}
