### Typannotationen und Tooling

Sehen wir uns zunächst an, wie Editor, mypy und andere Tools dies sehen würden.

`BaseUser` verfügt über die Basis-Felder. Dann erbt `UserIn` von `BaseUser` und fügt das Feld `Passwort` hinzu, sodass dass es nun alle Felder beider Modelle hat.

Wir annotieren den Funktionsrückgabetyp als `BaseUser`, geben aber tatsächlich eine `UserIn`-Instanz zurück.

**verschlüsselt**, auch wenn sie mit dem **HTTP-Protokoll** gesendet werden.

Es ist eine gängige Praxis, **ein Programm/HTTP-Server** auf dem Server (der Maschine, dem Host usw.) laufen zu lassen, welches **alle HTTPS-Aspekte verwaltet**: Empfangen der **verschlüsselten HTTPS-Requests**, Senden der **entschlüsselten HTTP-Requests** an die eigentliche HTTP-Anwendung die auf demselben Server läuft (in diesem Fall die **FastAPI**-Anwendung), entgegennehmen der **HTTP-Response** von der Anwendung, **verschlüsseln...
