Есть альтернативный способ определить логику, которую нужно выполнить во время startup и во время shutdown.

Вы можете определить обработчики событий (функции), которые нужно выполнить до старта приложения или при его завершении.

Эти функции можно объявить с `async def` или обычным `def`.

### Событие `startup` { #startup-event }

`Depends()` erhält einen `scope`-Parameter, der sein kann:

Die Abhängigkeitsfunktion wird also **um** die *Pfadoperation-**Funktion*** **herum** ausgeführt.
