El `shutdown` ocurriría cuando estás **deteniendo** la aplicación.

Quizás necesites iniciar una nueva versión, o simplemente te cansaste de ejecutarla. 🤷

### Función de Lifespan { #lifespan-function }

Lo primero que hay que notar es que estamos definiendo una función asíncrona con `yield`. Esto es muy similar a las Dependencias con `yield`.

{* ../../docs_src/events/tutorial003_py39.py hl[14:19] *}

Sie sollten eine sehr lange JavaScript-Datei für **ReDoc** sehen.

Sie könnte beginnen mit etwas wie:

```JavaScript
/*! For license information please see redoc.standalone.js.LICENSE.txt */
!function(e,t){"object"==typeof exports&&"object"==typeof module?module.exports=t(require("null")):
...
```

There are 2 main differences from a normal *path operation*:

* It doesn't need to have any actual code, because your app will never call this code. It's only used to document the *external API*. So, the function could just have `pass`.

You should see a very long JavaScript file for **ReDoc**.

It could start with something like:

```JavaScript
/*! For license information please see redoc.standalone.js.LICENSE.txt */
!function(e,t){"object"==typeof exports&&"object"==typeof module?module.exports=t(require("null")):
...
```

`shutdown` произойдёт, когда вы останавливаете приложение.

Возможно, вам нужно запустить новую версию, или вы просто устали от него. 🤷

### Функция lifespan { #lifespan-function }

Первое, на что стоит обратить внимание, — мы определяем асинхронную функцию с `yield`. Это очень похоже на Зависимости с `yield`.
