Chapter 8 Input Validation

Sandwich Maker

Write a program that asks users for their sandwich preferences. The program 
should use PyInputPlus to ensure that they enter valid input, such as:
•   Using inputMenu() for a bread type: wheat, white, or sourdough.
•   Using inputMenu() for a protein type: chicken, turkey, ham, or tofu.
•   Using inputYesNo() to ask if they want cheese.
•   If so, using inputMenu() to ask for a cheese type: cheddar, Swiss,
    or mozzarella.
•   Using inputYesNo() to ask if they want mayo, mustard, lettuce, or tomato.
•   Using inputInt() to ask how many sandwiches they want. Make sure this
    number is 1 or more.
Come up with prices for each of these options, and have your program
display a total cost after the user enters their selection
