Nota que en este caso estamos usando una función estándar de Python `open()` que interactúa con un archivo.

Entonces, involucra I/O (entrada/salida), que requiere "esperar" para que las cosas se escriban en el disco.

Pero `open()` no usa `async` y `await`.

Por eso, declaramos la función manejadora del evento con `def` estándar en vez de `async def`.

Wenn Sie FastAPI installieren (z. B. mit `pip install "fastapi[standard]"`), erhalten Sie ein Kommandozeilenprogramm, das Sie im Terminal ausführen können.

Um Ihre FastAPI-App für die Entwicklung auszuführen, können Sie den Befehl `fastapi dev` verwenden:

<div class="termy">

```console

**FastAPI <abbr title="command line interface">CLI</abbr>** is a command line program that you can use to serve your FastAPI app, manage your FastAPI project, and more.

When you install FastAPI (e.g. with `pip install "fastapi[standard]"`), it comes with a command line program you can run in the terminal.

To run your FastAPI app for development, you can use the `fastapi dev` command:

<div class="termy">

```console

Quando você instala o FastAPI (por exemplo, com `pip install "fastapi[standard]"`), ele vem com um programa de linha de comando que você pode executar no terminal.

Para executar sua aplicação FastAPI durante o desenvolvimento, você pode usar o comando `fastapi dev`:

<div class="termy">

```console

**FastAPI** will create the object of type `BackgroundTasks` for you and pass it as that parameter.

## Create a task function { #create-a-task-function }

Create a function to be run as the background task.

It is just a standard function that can receive parameters.

It can be an `async def` or normal `def` function, **FastAPI** will know how to handle it correctly.

In this case, the task function will write to a file (simulating sending an email).

# OAuth2 scopes { #oauth2-scopes }

You can use OAuth2 scopes directly with **FastAPI**, they are integrated to work seamlessly.

This would allow you to have a more fine-grained permission system, following the OAuth2 standard, integrated into your OpenAPI application (and the API docs).

```Python
my_list: list[str]
```

Das ist alles Standard-Python-Syntax für Typdeklarationen.

Verwenden Sie dieselbe Standardsyntax für Modellattribute mit inneren Typen.

In unserem Beispiel können wir also bewirken, dass `tags` spezifisch eine „Liste von Strings“ ist:
