### OpenAPI-spezifische `examples` { #openapi-specific-examples }

Schon bevor **JSON Schema** `examples` unterstützte, unterstützte OpenAPI ein anderes Feld, das auch `examples` genannt wurde.

    * Étant donné que se connecter à un serveur et envoyer un email a tendance à être «lent» (plusieurs secondes), vous pouvez retourner la réponse directement et envoyer la notification en arrière-plan.
* Traiter des données :
    * Par exemple, si vous recevez un fichier qui doit passer par un traitement lent, vous pouvez retourner une réponse «Accepted» (HTTP 202) puis faire le traitement en arrière-plan.


## Utiliser `BackgroundTasks`

To add a function that should be run when the application is shutting down, declare it with the event `"shutdown"`:

{* ../../docs_src/events/tutorial002_py39.py hl[6] *}

Here, the `shutdown` event handler function will write a text line `"Application shutdown"` to a file `log.txt`.

### What is a Program { #what-is-a-program }

The word **program** is commonly used to describe many things:

* The **code** that you write, the **Python files**.
* The **file** that can be **executed** by the operating system, for example: `python`, `python.exe` or `uvicorn`.
