# 環境變數 { #environment-variables }

/// tip

如果你已經知道什麼是「環境變數」並且知道如何使用它們，你可以放心跳過這一部分。

///

環境變數（也稱為「**env var**」）是一個獨立於 Python 程式碼**之外**的變數，它存在於**作業系統**中，可以被你的 Python 程式碼（或其他程式）讀取。

環境變數對於處理應用程式**設定**（作為 Python **安裝**的一部分等方面）非常有用。

## 建立和使用環境變數 { #create-and-use-env-vars }

你在 **shell（終端機）**中就可以**建立**和使用環境變數，並不需要用到 Python：
