Question

Create a python program that:

• Creates a sales receipt, displays the receipt entries and totals, and saves the receipt entries to a file
  • Prompt the user to enter the
    • Item Name
    • Item Quantity
    • Item Price
  • Display the item name, the quantity, and item price, and the extended price (Item Quantity multiplied by Item Price) after the entry is made
  • Save the item name, quantity, item price, and extended price to a file
    • When you create the file, prompt the user for the name they want to give the file
    • Separate the items saved with commas
    • Each entry should be on a separate line in the text file
  • Ask the user if they have more items to enter
• Once the user has finished entering items
  • Close the file with the items entered
  • Display the sales total
  • If the sales total is more than $100
    • Calculate and display a 10% discount
  • Calculate and display the sales tax using 8% as the sales tax rate
    • The sales tax should be calculated on the sales total after the discount
  • Display the total for the sales receipt

Answer 1

Below is a screen shot of the python program to check indentation. Comments are given on every line explaining the code.

Below is the output of the program:

Below is the code to copy:
#CODE STARTS HERE----------------

#input file name
file_name = input("Enter file name: ")
file = open(file_name, "a+")
total_cost = 0 #Set total cost to 0
while True: #loops until user enters "n"
   #Get input
   name = input("\nEnter item name: ")
   quantity = int(input("Enter item quantity: "))
   price = float(input("Enter item price: "))
   #Calculate total cost
   extended_price = price*quantity
   total_cost += extended_price

   #Print item details
   print("\nItem name:",name)
   print("Item quantity:",quantity)
   print("Item price:",price)
   print("Item extended price:", extended_price)

   #Write items to the file
   file.write(name+","+str(quantity)+","+str(price)+","+str(price*quantity)+"\n")
   #Ask user for another item
   add_item = input("Do you want to add another item?(y/n)")
   if add_item.lower() == "n":
      file.close() #Close file
      break #break out of the loop

#print total cost
print("\nTotal cost: ",total_cost)
#Calculate and print discount
if total_cost > 100:
   discount = total_cost*0.1
   print("Discount :", discount)
   total_cost -= discount
   print("Total cost after discount: ",total_cost)

#Calsulate and print tax and grand total
print("Sales tax: ", total_cost*0.08)
total_cost = total_cost * 1.08
print("Grand total: ", round(total_cost,2))
