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 offirst_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.

Answer 1

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


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"]
    phone_book = combine_lists(last_name, first_name, phone_number)
    for l_name, value in phone_book.items():
        print(value[0] + " " + l_name + ", Number: " + value[1])
    last = input("Enter a last name: ")
    if last in phone_book:
        print("Number of " + last + " is " + phone_book[last][0])


main()
