4. **Lease Sharing**: Support lease sharing across handles

## Eine Taskfunktion erstellen { #create-a-task-function }

Erstellen Sie eine Funktion, die als Hintergrundtask ausgeführt werden soll.

Es handelt sich schlicht um eine Standard-Funktion, die Parameter empfangen kann.

Es kann sich um eine `async def`- oder normale `def`-Funktion handeln. **FastAPI** weiß, wie damit zu verfahren ist.

In diesem Fall schreibt die Taskfunktion in eine Datei (den Versand einer E-Mail simulierend).
