### `startup` イベント { #startup-event }

アプリケーションが開始される前に実行すべき関数を追加するには、イベント `"startup"` で宣言します:

{* ../../docs_src/events/tutorial001_py310.py hl[8] *}

この場合、`startup` のイベントハンドラ関数は items の「データベース」（単なる `dict`）をいくつかの値で初期化します。

イベントハンドラ関数は複数追加できます。

すべての `startup` イベントハンドラが完了するまで、アプリケーションはリクエストの受け付けを開始しません。
