Python Tag 68 – Woche 12 Hausaufgaben

Thema:

Anforderungen:

Benutzerrolle, Dozent＼Student. Nach dem Anmelden kann der Benutzer je nach Rolle verschiedene Dinge tun, wie folgt:
Dozentenansicht
Klassen verwalten, Klassen erstellen und Studenten entsprechend der Klasse hinzufügen QQ-Nummer des Schülers
Sie können Klassendatensätze für bestimmte Klassen erstellen. Beachten Sie, dass ein Klassendatensatz mehreren Schülerklassendatensätzen entspricht, d. h., jede Klasse hat eine ganze Klasse von Schülern. Sie müssen vorher jeden Klassendatensatz erstellen und gleichzeitig einen Klassendatensatz für jeden Schüler in dieser Klasse erstellen
Noten für Schüler korrigieren, Noten einzeln manuell ändern
Schüleransicht
Hausaufgaben einreichen
Hausaufgabennoten anzeigen
Ein Schüler kann gleichzeitig mehreren Klassen angehören, genau wie Sie sich gleichzeitig für Linux und Python anmelden können. Wenn Sie also Hausaufgaben einreichen, müssen Sie zuerst die Klasse und dann die spezifische Nummer auswählen Anzahl der Klassen
Zusätzlich: Schüler können die Rangfolge ihrer Klassenergebnisse überprüfen
