Sie sind jedoch nicht auf die Verwendung von bestimmten Datenmodellen, Klassen, oder Typen beschränkt.

Möchten Sie eine `id` und eine `email` und keinen `username` in Ihrem Modell haben? Kein Problem. Sie können dieselben Tools verwenden.

Let's imagine that loading the model can **take quite some time**, because it has to read a lot of **data from disk**. So you don't want to do it for every request.

You could load it at the top level of the module/file, but that would also mean that it would **load the model** even if you are just running a simple automated test, then that test would be **slow** because it would have to wait for the model to load before being able to run an independent part of the code.

### Erforderlich, kann `None` sein

Sie können deklarieren, dass ein Parameter `None` akzeptiert, aber dennoch erforderlich ist. Das zwingt Clients, den Wert zu senden, selbst wenn er `None` ist.

Um das zu machen, deklarieren Sie, dass `None` ein gültiger Typ ist, aber verwenden Sie dennoch `...` als Default:

        subgraph venv2[.venv]
            harry-3[harry v3]
        end

When you activate a virtual environment, for example with:

```console
$ source .venv/bin/activate
