Then, do the following:
      • Add a new pizza to the original list.
      • Add a different pizza to the list friend_pizzas.
      • Prove that you have two separate lists. Print the message My favorite
      pizzas are:, and then use a for loop to print the first list. Print the message
      My friend’s favorite pizzas are:, and then use a for loop to print the second
      list. Make sure each new pizza is stored in the appropriate list.
