Delete Contact

Part of the Logic & Flow section of Coddy's GDScript journey. Lesson 28 of 78.

Challenge

Easy

Handle the choice 4, deleting a contact. Keep everything you wrote in the previous steps.

Write delete_contact(contact_book: Dictionary). It reads a name. If the name is in contact_book, remove that contact and print:

Contact deleted successfully!

Otherwise print Contact not found!

In the loop, add an elif branch for "4" that calls delete_contact(contact_book).

Try it yourself

func _ready():
	var contact_book := {}

	while true:
		display_menu()
		var choice := OS.read_string_from_stdin()
		if choice == "1":
			add_contact(contact_book)
		elif choice == "2":
			view_contact(contact_book)
		elif choice == "3":
			edit_contact(contact_book)
		elif choice == "6":
			break
