   - Implementieren Sie eine Funktion ''graduate_student(student: Student) -> Student'', die eine neue Instanz der Dataclass zurückgibt, bei der das Attribut ''graduated'' auf ''True'' gesetzt wird, wenn der Notendurchschnitt 70 oder mehr beträgt.
   - Schreiben Sie ein Programm, das mehrere Noten hinzufügt, den Durchschnitt berechnet und den Studenten "absolviert", falls die Kriterien erfüllt sind. Geben Sie die Ergebnisse aus.
