然後你可以呼叫這個 Python 程式：

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

<div class="termy">

```console
// 這裡我們還沒有設定環境變數
$ python main.py

// 因為我們沒有設定環境變數，所以我們得到的是預設值

Hello World from Python

// 但是如果我們事先建立過一個環境變數
$ export MY_NAME="Wade Wilson"

// 然後再次呼叫程式
$ python main.py

// 現在就可以讀取到環境變數了

Hello Wade Wilson from Python
```

</div>

////

//// tab | Windows PowerShell
