 * <p>Basic usage:
 *
 * {@snippet :
 * Stopwatch stopwatch = Stopwatch.createStarted();
 * doSomething();
 * stopwatch.stop(); // optional
 *
 * Duration duration = stopwatch.elapsed();
 *
 * log.info("time: " + stopwatch); // formatted string like "12.3 ms"
 * }
 *
 * <p>The state-changing methods are not idempotent; it is an error to start or stop a stopwatch
 * that is already in the desired state.

Aquí, la función manejadora del evento `shutdown` escribirá una línea de texto `"Application shutdown"` a un archivo `log.txt`.

/// info | Información

En la función `open()`, el `mode="a"` significa "añadir", por lo tanto, la línea será añadida después de lo que sea que esté en ese archivo, sin sobrescribir el contenido anterior.

### `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。
