/// tip | 豆知識

`shutdown` は、アプリケーションを「停止」するときに発生します。

新しいバージョンを開始する必要があるか、単に実行をやめたくなったのかもしれません。🤷

### Lifespan 関数 { #lifespan-function }

まず注目すべきは、`yield` を使う非同期関数を定義していることです。これは「yield を使う依存関係（Dependencies）」にとてもよく似ています。

{* ../../docs_src/events/tutorial003_py310.py hl[14:19] *}

`yield` の前の前半は、アプリケーションが開始される「前」に実行されます。

/// tip | İpucu

[ *path operation decorator*’larındaki dependency’lerde](dependencies/dependencies-in-path-operation-decorators.md) olduğu gibi, *path operation function*’ınıza herhangi bir değer aktarılmayacağını unutmayın.

///

Sonuç olarak item path’leri artık:

* `/items/`
* `/items/{item_id}`

...tam da istediğimiz gibi olur.
