How Can I Add a Receipt?

Question

Hello I'm working on an assignment and I want to figure out how I would be able to save which items the user chooses and how many times he chooses that item so I can form a receipt. This is what I have so far. Any help would be amazing!

#Here we have a welcome message along with directions on how to access the menu! We also have a goodbye message for future use

print("Welcome to big Johnny's Cafe!")

print("We have a wide selection of drinks and food to choose from!")

x = input("If you want to see our Menu type out 'menu': ")

tym = "Thank you for coming to Big Johnny's Cafe! We hope we see you again!"

#Here is me setting up the value of each item in the menu

Blueberry_Muffin = 1.25

Chocolate_Muffin = 1.50

Chocolate_Chip_Cookie = 0.50

Rainbow_Sprinkle_Cookie = 0.50

Coffee = 3.50

Croissant = 1.00

#I put that total is equal to zero so I'm able to add onto the total later on without it resetting or whatever

total = 0.0

#The reason I put this here is because I plan on using a while loop that will continue until the user is finished ordering!

finished = False

#This is to recognize that the user input was menu and this displays the menu

if x == "menu":

print(" ")

print("Our Menu Includes:")

print(" ")

print("1 Blueberry Muffin $"+str(Blueberry_Muffin))

print("2 Chocolate Muffin $"+str(Chocolate_Muffin))

print("3 Chocolate Chip Cookie $"+str(Chocolate_Chip_Cookie))

print("4 Rainbow Sprinkle Cookie $"+str(Rainbow_Sprinkle_Cookie))

print("5 Coffee(Standard Medium) $"+str(Coffee))

print("6 Croissant $"+str(Croissant))

print(" ")

#The reason I put this here is because I plan on using a while loop that will continue until the user is finished ordering!

finished = False

#Here is a while loop that is used to let the customer decide how much stuff they want until they are finished

while(not finished):

print("Total:", total);

choice = input("Select a number or type 'finished' when you have finished ordering: ");

if choice == "1":

total += Blueberry_Muffin;

elif choice == "2":

total += Chocolate_Muffin;

elif choice == "3":

total += Chocolate_Chip_Cookie;

elif choice == "4":

total += Rainbow_Sprinkle_Cookie;

elif choice == "5":

total += Coffee;

elif choice == "6":

total += Croissant;

elif choice == "finished":

print("Subtotal: $"+ str(total));

tend = total*.1

print("10% off -"+str(tend))

print("Subtotal: $"+ str(total-tend))

fifd = total*.15

print("15% off -"+str(fifd))

print("Subtotal: $"+ str(total-fifd))

tax = total*.06625

print("Tax +"+str(tax))

print(" Total: $"+ str(total+tax))

finished = True

The best way is to create a class to store the name ,price, and quantity ordered.

Next create an array of these objects which can then be displayed in the menu, sub totaled, and receipt created.

The other option is to create the dictionary for the name and price. You then need an array to store the quantity ordered.

Keeping 3 arrays is bad idea.

class Item:

def __init__(self, name, price):

self.name = name

self.price = price

def GetName(self):

return (self.name)

def GetPrice(self):

return(self.price)

def GetQty(self):

return(self.qty)

def SetQty(self,qty):

self.qty = qty

def Subtotal(self):

return( float(self.price)*int(self.qty))

for i in range(N):

print( str(i+1) + " " +

items[i].GetName() + " "+

str(items[i].GetPrice()) + " "+

str(items[i].GetQty()) + " " +
