這些環境變數只能處理**文字字串**，因為它們是位於 Python 範疇之外的，必須與其他程式和作業系統的其餘部分相容（甚至與不同的作業系統相容，如 Linux、Windows、macOS）。

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：

# Treat all files in the Go repo as binary, with no git magic updating
# line endings. This produces predictable results in different environments.
#
# Windows users contributing to Go will need to use a modern version
# of git and editors capable of LF line endings.
#
# Windows .bat files are known to have multiple bugs when run with LF
# endings, and so they are checked in with CRLF endings, with a test

    PULL_REQUEST_FEEDBACK("Pull Request Feedback", "Run various functional tests", "PullRequestFeedback"),
    READY_FOR_NIGHTLY(
        "Ready for Nightly",

    synchronized(cache) { cache.initialize() }
  }

  fun setUp(
    baseFilesystem: FileSystem,
    windows: Boolean,
  ) {
    this.cacheDir =
      if (baseFilesystem is FakeFileSystem) "/cache".toPath() else cacheDirFile.path.toPath()
    this.filesystem = FaultyFileSystem(baseFilesystem)
    this.windows = windows

    if (filesystem.exists(cacheDir)) {
      filesystem.deleteRecursively(cacheDir)
    }
