安裝 Python 時，可能會詢問你是否要更新 `PATH` 環境變數。

//// tab | Linux, macOS

假設你安裝了 Python，並將其安裝在目錄 `/opt/custompython/bin` 中。

如果你選擇更新 `PATH` 環境變數，那麼安裝程式會將 `/opt/custompython/bin` 加入到 `PATH` 環境變數中。

它看起來大致會是這樣：

```plaintext
/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/custompython/bin
```

如此一來，當你在終端機輸入 `python` 時，系統會在 `/opt/custompython/bin` 中找到 Python 程式（最後一個目錄）並使用它。
