环境变量（也称为"env var"）是一种存在于 Python 代码之外、存在于操作系统中的变量，可以被您的 Python 代码（或其他程序）读取。

您可以在 shell 中创建和使用环境变量，而无需使用 Python：

//// tab | Linux、macOS、Windows Bash

<div class="termy">

```console
// 您可以创建一个名为 MY_NAME 的环境变量
$ export MY_NAME="Wade Wilson"

// 然后您可以与其他程序一起使用它，例如
$ echo "Hello $MY_NAME"

Hello Wade Wilson
```

</div>

////

//// tab | Windows PowerShell
