### Событие `shutdown` { #shutdown-event }

Чтобы добавить функцию, которую нужно запустить при завершении работы приложения, объявите её как обработчик события `"shutdown"`:

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

Здесь функция-обработчик события `shutdown` запишет строку текста `"Application shutdown"` в файл `log.txt`.
