这意味着从环境变量中读取的**任何值**在 Python 中都将是一个 `str`，任何类型转换或验证都必须在代码中完成。

你将在[高级用户指南 - 设置和环境变量](./advanced/settings.md)中了解更多关于使用环境变量处理**应用程序设置**的信息。

## `PATH` 环境变量 { #path-environment-variable }

有一个**特殊的**环境变量称为 **`PATH`**，操作系统（Linux、macOS、Windows）用它来查找要运行的程序。

`PATH` 变量的值是一个长字符串，由 Linux 和 macOS 上的冒号 `:` 分隔的目录组成，而在 Windows 上则是由分号 `;` 分隔的。

例如，`PATH` 环境变量可能如下所示：

//go:build windows
// +build windows

### 3.3 Use GnuTLS (for Windows) to Generate a Certificate

This section describes how to use GnuTLS on Windows to generate a certificate.

#### 3.3.1 Install and configure GnuTLS

Download and decompress the Windows version of GnuTLS from [here](http://www.gnutls.org/download.html).

環境変数は、Pythonを必要とせず、**シェル（ターミナル）**で**作成**して使用できます。

//// tab | Linux, macOS, Windows Bash

<div class="termy">

```console
// 環境変数 MY_NAME を作成する例
$ export MY_NAME="Wade Wilson"

// その後、他のプログラムで利用できます。例えば
$ echo "Hello $MY_NAME"

Hello Wade Wilson
```

</div>

////

//// tab | Windows PowerShell

<div class="termy">

```console
// 環境変数 MY_NAME を作成
