Eliminar contacto

Parte de la sección Lógica y flujo del Journey de GDScript de Coddy. Lección 28 de 78.

Desafío

Fácil

Gestiona la opción 4, eliminando un contacto. Conserva todo lo que escribiste en los pasos anteriores.

Escribe delete_contact(contact_book: Dictionary). Lee un nombre. Si el nombre está en contact_book, elimina ese contacto e imprime:

Contact deleted successfully!

De lo contrario, imprime Contact not found!

En el bucle, añade una rama elif para "4" que llame a delete_contact(contact_book).
