Python Need some help with my code

[Predict]

that's the question and the code beneath

(Total Purchase) A customer in a store can purchase any one of the five items listed below: The prices of the five items are:



Price of item 1 = 12.95

Price of item 2 = 24.95

Price of item 3 = 6.95

Price of item 4 = 14.95

Price of item 5 = 24.95

Write a program that prompts the user to enter the quantity and item # of the product being bought. You should then calculate and print the subtotal of the sale, the amount of sales tax, and the total. Assume the sales tax is 6% (declared as a constant).


item1 = (12.95)
item2 = (24.95)
item3 = (6.95)
item4 = (14.95)
item5 = (24.95)
SALES_TAX = .06

choice = int(input("Enter an item: item1, item2, item3, item4, item5\n"))
quantity = input("Enter quantity: ")
quantity = float(quantity)
item_no = input("Enter item number: ")
item_no = float(item_no)
while True:
if choice == float(item1):

choice = int(input('Would you like to pick another order? y/n\n'))
if choice == 'y':
choice = int(input("Enter item1 again: "))
else:
subtotal = quantity * choice
SALES_TAX = subtotal*SALES_TAX
total = subtotal + SALES_TAX

print ("your subtotal is: ",subtotal )
print ("your sales tax is: ", SALES_TAX )
print ("your total is: ", total )

I would recommend having a look at python dicts. They will make the job easier. When I get home from work I have an old script I will post for you break down. It gets items amount and does the taxes.

Here is the code I wrote a while back. If I rewrote it would probably do it a little different but, anyhow, maybe it will help get you started.

    def add_tax(self, total, tax):
        return total*tax

Thanks but I don't think the code is that complex 😐 I did it back over and got the expected output but thanks. this is the code that I wrote.

item1 = (12.95)
item2 = (24.95)
item3 = (6.95)
item4 = (14.95)
item5 = (24.95)
SALES_TAX = .06
itemno = int(input("Enter Item number:\nitem1 = 12.95 \nitem2 = 24.95\nitem3 = 6.95\nitem4 = 14.95\nitem5 = 24.95\n\n"))
if itemno >= 6:
print("Item not found")
else:
quantity = int(input("Enter quantity of product: "))

if itemno == 1:
subtotal = int(quantity * item1)
SALES_TAX = int(subtotal) * SALES_TAX
total = subtotal + SALES_TAX
elif itemno == 2:
subtotal = int(quantity * item2)
SALES_TAX = int(subtotal) * SALES_TAX
total = subtotal + SALES_TAX
elif itemno == 3:
subtotal = int(quantity * item3)
SALES_TAX = int(subtotal) * SALES_TAX
total = subtotal + SALES_TAX
elif itemno == 4:
subtotal = int(quantity * item4)
SALES_TAX = int(subtotal) * SALES_TAX
total = subtotal + SALES_TAX
elif itemno == 5:
subtotal = int(quantity * item5)
SALES_TAX = int(subtotal) * SALES_TAX
total = subtotal + SALES_TAX
else:
print("Item not found")

print("The subtotal of your purchase is: ", subtotal)
print("The sales tax is %0.2f" %SALES_TAX)
print("The total of your purchase is: ", total)

Wow that is some big ugly lump of code... Why don't you post code in proper BBCode tags ? It's one of the first rules of this forum.
I see you favor enumeration over iteration. Not the way any programmer would do it, more like how an accountant would do it. Anyway you can be glad this tiny store has only 5 items for sale 😉
