Alle auflisten

Teil des Abschnitts Logik & Ablaufsteuerung der GDScript-Journey von Coddy. Lektion 29 von 78.

Aufgabe

Einfach

Behandle die Auswahl 5 und liste alle Kontakte auf. Behalte alles bei, was du in den vorherigen Schritten geschrieben hast.

Schreibe list_all_contacts(contact_book: Dictionary). Die Funktion liest keine Eingabe. Wenn contact_book leer ist, gibt sie Folgendes aus:

No contacts available.

Andernfalls gibt sie jeden Kontakt in der Reihenfolge aus, in der er hinzugefügt wurde, im selben vierzeiligen Format wie view_contact(), gefolgt von einer Leerzeile. Mit Alice und Bob im Verzeichnis lautet die Ausgabe:

Name: Alice
Phone: 123-456-7890
Email: alice@example.com
Address: 123 Main St

Name: Bob
Phone: 234-567-8901
Email: bob@example.com
Address: 456 Oak Ave

Füge in der Schleife einen elif-Zweig für "5" hinzu, der list_all_contacts(contact_book) aufruft.
