### `shutdown` 事件 { #shutdown-event }

要加入一個在應用關閉時執行的函式，使用事件 `"shutdown"` 來宣告：

{* ../../docs_src/events/tutorial002_py310.py hl[6] *}

在這裡，`shutdown` 事件處理器函式會把一行文字 `"Application shutdown"` 寫入檔案 `log.txt`。

/// info

在 `open()` 函式中，`mode="a"` 表示「append（附加）」；也就是說，這行文字會加在檔案現有內容之後，而不會覆寫先前的內容。

///

/// tip

注意這裡我們使用的是標準 Python 的 `open()` 函式來操作檔案。

這涉及 I/O（輸入／輸出），也就是需要「等待」資料寫入磁碟。
