接著，在 `yield` 之後，我們卸載模型。這段程式會在應用**完成處理請求之後**、也就是 *shutdown* 前執行。這可以用來釋放資源，例如記憶體或 GPU。

/// tip

`shutdown` 會在你**停止**應用程式時發生。

也許你要啟動新版本，或只是不想再跑它了。🤷

### Lifespan 函式 { #lifespan-function }

首先要注意的是，我們定義了一個帶有 `yield` 的 async 函式。這和帶有 `yield` 的依賴（Dependencies）非常相似。

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

函式在 `yield` 之前的部分，會在應用啟動前先執行。

`yield` 之後的部分，會在應用結束後再執行。
