これらの環境変数が扱えるのは**テキスト文字列**のみです。環境変数はPythonの外部にあり、他のプログラムやシステム全体（Linux、Windows、macOSなど異なるオペレーティングシステム間も）との互換性が必要になるためです。

つまり、環境変数からPythonで読み取る**あらゆる値**は **`str`になり**、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。

環境変数を使って**アプリケーション設定**を扱う方法については、[高度なユーザーガイド - Settings and Environment Variables](./advanced/settings.md)で詳しく学べます。

## `PATH`環境変数 { #path-environment-variable }

**`PATH`**という**特別な**環境変数があります。これはオペレーティングシステム（Linux、macOS、Windows）が実行するプログラムを見つけるために使用されます。
