Question

Write a program that does the following in Python Code:

• Stores the following three lists:

last_name = ["Smith", "Jones", "Williams", "Bailey", "Rogers", "Pyle", "Rossington"]

first_name =["Lisa", "Bill", "Jay", "Sally", "Walter","Jake","Gary"]

phone_number =["240-233-1921", "301-394-2745", "571-321-8934", "703-238-3432", "703-947-9987", "301-945-3593", "240-671-3221"]

• Has a function named combine_lists() that takes in last_names, first_names and phone_numbers as lists and returns a dictionary called phone_book that uses last_name as the key and a list consisting of first_name and phone_number.
• Has a main function that iterates through the phone_book and prints out its contents.
• Also, prompt the user to enter a last name and print out the corresponding contact information. When entering the last name of that person, the output should print the first name and phone number of that person.

Answer 1

def combine_lists(last_names, first_names, phone_numbers):
    contacts = {}
    for i in range(len(last_names)):
        contacts[last_names[i]] = [first_names[i], phone_numbers[i]]
    return contacts


def main():
    last_name = ["Smith", "Jones", "Williams", "Bailey", "Rogers", "Pyle", "Rossington"]
    first_name = ["Lisa", "Bill", "Jay", "Sally", "Walter", "Jake", "Gary"]
    phone_number = ["240-233-1921", "301-394-2745", "571-321-8934", "703-238-3432", "703-947-9987", "301-945-3593",
                    "240-671-3221"]
    contacts = combine_lists(last_name, first_name, phone_number)
    for last_name, data in contacts.items():
        print(data[0] + " " + last_name + ", Number: " + data[1])
    last = input("\nEnter a last name: ")
    if last in contacts:
        print("Phone number of " + contacts[last][0] + ' ' + last + " is " + contacts[last][1])


main()
