"A contact book is a place where you can store a specific contact with other associated information such as a phone number, email address, birthday, etc. Your contact book stores names and phone numbers. Write a program that uses the given dictionary and updates the phone numbers in it. Your program is only expected to update the area codes of phone numbers. Your program should first display all contacts by name and number. Then prompt for the current area code, followed by a prompt for the new area code as shown below. Your prompts should end with a newline so that each input is on its own line. Update the contact book by replacing the current area code with the new area code. You will then display all contacts by name and number that are in the updated contact book. If there were no updates, display that message instead of the contact book."
