Daftar Semua Kontak

Termasuk bagian Logika dan Alur dalam perjalanan GDScript di Coddy. Pelajaran 29 dari 78.

Tantangan

Mudah

Tangani pilihan 5, dengan menampilkan setiap kontak. Pertahankan semua yang kamu tulis pada langkah sebelumnya.

Tulis list_all_contacts(contact_book: Dictionary). Fungsi ini tidak membaca input. Jika contact_book kosong, fungsi ini mencetak:

No contacts available.

Jika tidak, fungsi ini mencetak setiap kontak sesuai urutan penambahannya, dengan format empat baris yang sama seperti view_contact(), lalu satu baris kosong. Jika Alice dan Bob ada di dalam buku kontak, output-nya adalah:

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

Di dalam perulangan, tambahkan cabang elif untuk "5" yang memanggil list_all_contacts(contact_book).
