這意味著從環境變數中讀取的**任何值**在 Python 中都將是一個 `str`，任何型別轉換或驗證都必須在程式碼中完成。

你將在[進階使用者指南 - 設定和環境變數](./advanced/settings.md)中了解更多關於使用環境變數處理**應用程式設定**的資訊。

## `PATH` 環境變數

有一個**特殊的**環境變數稱為 **`PATH`**，作業系統（Linux、macOS、Windows）用它來查找要執行的程式。

`PATH` 變數的值是一個長字串，由 Linux 和 macOS 上的冒號 `:` 分隔的目錄組成，而在 Windows 上則是由分號 `;` 分隔的。

例如，`PATH` 環境變數可能如下所示：

//// tab | Linux, macOS

```plaintext
/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin
```
