Kontakt löschen

Teil des Abschnitts Logik & Ablaufsteuerung der GDScript-Journey von Coddy. Lektion 28 von 78.

Aufgabe

Einfach

Behandle die Auswahl 4, indem du einen Kontakt löschst. Behalte alles bei, was du in den vorherigen Schritten geschrieben hast.

Schreibe delete_contact(contact_book: Dictionary). Die Funktion liest einen Namen ein. Wenn der Name in contact_book enthalten ist, entferne den Kontakt und gib Folgendes aus:

Contact deleted successfully!

Andernfalls gib Contact not found! aus.

Füge in der Schleife einen elif-Zweig für "4" hinzu, der delete_contact(contact_book) aufruft.
