环境变量对于处理应用程序**设置**、作为 Python **安装**的一部分等方面非常有用。

## 创建和使用环境变量

你在 **shell（终端）**中就可以**创建**和使用环境变量，并不需要用到 Python：

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

<div class="termy">

```console
// 你可以使用以下命令创建一个名为 MY_NAME 的环境变量
$ export MY_NAME="Wade Wilson"

// 然后，你可以在其他程序中使用它，例如
$ echo "Hello $MY_NAME"

Hello Wade Wilson
```

</div>
