Question

Python: Write a program for a small restaurant that sells pizzas. You may consider it as a prototype of a realistic online application. Basically, your program allows a user to enter one’s name and information about pizzas that the user wants to order. It then calculates and displays the subtotal, sales tax, and total cost of the order.
Given below is a typical dialog between a user and your program when the user interacts with your program to place an order of one or more pizzas. Note that the text in black is program output, such as asking the user for certain input or displaying relevant information for the user, and the text in red is the user’s response to a prompt from your program.

Enter your name: John

Pizza Size and Cost

- Small (10 inch, $7.95), Medium (12 inch, $9.95), and Large (14 inch, $11.95) Enter the size of your pizzas: Medium

Explanation:

name = input("Name: ")

num_pizzas = int(input("Number of pizzas: "))

print("Small (10 inch, $7.95), Medium (12 inch, $9.95), and Large (14 inch, $11.95)")

pizza_size = input("Pizza size: ").lower()

print("Available toppings: Ham, Mushrooms, Onions, Green Peppers, Black Olives, Tomatoes, Pineapple, Spinach")

print("$0.75 each for Small Pizza, $0.95 each for Medium Pizza, and $1.15 each for Large Pizza")

num_toppings = int(input("Number of toppings: "))

toppings = []

subtotal = 0

tax = 0

total = 0

for i in range(1,num_toppings + 1):

   toppings.append(input(f"Enter topping number {i}: "))

if pizza_size == 'small':

   subtotal += num_pizzas * 7.95

   subtotal += num_toppings * 0.75

   tax += subtotal * 0.06

   total += subtotal + tax

   print("Order Summary: ")

   print(f"Customer Name: {name}")

   print(f"{num_pizzas} {pizza_size} pizzas with {toppings}")

   print("Subtotal | Sales Tax (6%) | Total Cost")

   print(f"{subtotal} | {tax} | {total}")

if pizza_size == 'medium':

   subtotal += num_pizzas * 9.95

   subtotal += num_toppings * 0.95

   tax += subtotal * 0.06

   total += subtotal + tax

   print("Order Summary: ")

   print(f"Customer Name: {name}")

   print(f"{num_pizzas} {pizza_size} pizzas with {toppings}")

   print("Subtotal | Sales Tax (6%) | Total Cost")

   print(f"{subtotal} | {tax} | {total}")

if pizza_size == 'large':

   subtotal += num_pizzas * 11.95

   subtotal += num_toppings * 1.15

   tax += subtotal * 0.06

   total += subtotal + tax

   print("Order Summary: ")

   print(f"Customer Name: {name}")
