URGENT PYTHON

Create a class named PizzaOrder that stores information about a single pizza.

It should contain the following:

Constant value

MAX_TOPPINGS = 15

Private instance variables to store

size - the size of the pizza (either small, medium, or large)

num_toppings - the number of toppings

toppings - a list of strings ["cheese", "onions", "shrooms", "Grilled chicken", " ...]

A constructor that sets all of the instance variables.

A method add_topping() that will take a string parameter, topping, and append() it to the toppings list as long as the number it items in the list does not exceed the class's static MAX_TOPPINGS.

A method named calc_cost( ) that returns a double that is 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

__str___(self) - a method that returns a String containing the pizza size and the pizza cost as calculated by calc_cost( ).

Write test code to create several pizzas and output their descriptions.

For example, a large pizza with one cheese, one Grilled chicken, and two avocado toppings should cost a total of $22.

Sample run:

Size: Large, Cheese Toppings: 1 Grilled chicken Toppings: 0 onions Toppings: 1. Cost: 18.0 Size: Medium, Cheese Toppings: 2 Grilled chicken Toppings: 2 onions Toppings: 0. Cost: 20.0 Size: Small, Cheese Toppings: 2 Grilled chicken Toppings: 1 onions Toppings: 1. Cost: 18.0 Total of the order: 56.0
