Part One: Pizza Class:

Create a Pizza class which stores information about a single pizza. It contains the following:

-Instance variables to store the size of the pizza (small, medium or large), (1)the number of cheese toppings, (2)the number of pepperoni toppings, and the (3) number of mushroom toppings.

- Constructor: that takes four arguments and sets all of the corresponding instance variables

 and  that initializes all instance variables to the zero of their type.

- Methods to get (accessor) and set (mutator) each instance variable individually.

- A method called calcCost() that returns the cost of the pizza. Pizza cost is determined by: Small: $10 + $2 per topping Medium: $12 + $2 per topping Large: $14 + $2 per topping.

-A method which returns a string for the pizza size, quantity of each topping, and the pizza cost as calculated by the following example, a large pizza with 1 cheese, 2 pepperoni and 1 mushroom toppings should cost $22 (you can overwrite __str__).

Part Two: DeluxePizza

Take the Pizza class from the above and modify it in the following way:

• Rename it to DeluxePizza.
• Add a stuffedWithCheese (boolean) attribute to the
• Add a veggieTopping (integer) attribute to the class. This attribute keeps track of the number of vegetables toppings excluding mushrooms.
• Add a class attribute numberOfPizzas (integer) which will keep track of the number of

DeluxePizza objects created (this is not an instance variable).

• Update the existing constructor such that it increments the numberOfPizzas by one(+ 1) each time it is called and requires 6 arguments instead of 4 to accommodate the two new attributes (stuffedWithCheese and veggieTopping).
• Modify the constructor to set the new attributes to “zero” and to increment the

numberOfPizzas attribute by one.

• Add an accessor and mutator method for the stuffedWithCheese and the veggieTopping

attributes.

• Add an accessor method for the numberOfPizzas (No mutator attribute.)
• Modify the calcCost() method to add $2, $4 or $6 dollars for cheese stuffed dough depending on the size of the pizza as well as an extra $3 per vegetable
• Modify the __str__ method so that when an object of type DeluxePizza is printed all of theattributes are displayed in the following format:

Pizza #

Pizza size:

Cheese filled dough:

Number of cheese toppings:

Number of pepperoni toppings:

Number of mushroom toppings:

Number of vegetable toppings:

Extra features must be included to spice up the pizzeria! Some sample ideas can include additional menu items (such as ice cream), trio combos, different (multiple) orders, additional users etc.
