______________________________________

Item 1	$__.__
Item 2	$_.__

Change to customer, if any	$__.__

Answer 1

Code:

prices = []

for i in range(4):
print("Enter the price of Item %d:"%(i+1))
price = int(raw_input(""))
while(price <= 5 or price >= 25):
print("Enter the price of Item %d:"%(i+1))
price = int(raw_input(""))
  
prices.append(price)

tax = 15
total = sum(prices)
taxAmount = total*(tax/100.0)
totalWithTax = total + taxAmount

customerPaid = int(raw_input("Customer paid is: "))
changeToCustomer = 0
if (customerPaid > totalWithTax):
changeToCustomer = customerPaid - totalWithTax
print(" SAMPLE RECEIPT OF ITEMS PURCHASED\n Item 1: \t\t $.%.2f\n Item 2: \t\t $.%.2f\n Item 3: \t\t $.%.2f\n Item 4: \t\t $.%.2f\n\n Total(for 4 items)\t $.%.2f\n Tax-%d %%\t\t $.%.2f\n Total(icl tax)\t\t $.%.2f\n\n Customer Paid \t\t $.%.2f\n Change to Customer\t $.%.2f\n"%(prices[0],prices[1],prices[2],prices[3],total,tax,taxAmount,totalWithTax,customerPaid,changeToCustomer))

Output:

 SAMPLE RECEIPT OF ITEMS PURCHASED
 Item 1:                 $.10.00
 Item 2:                 $.20.00
 Item 3:                 $.22.00
 Item 4:                 $.15.00

 Total(for 4 items)      $.67.00
 Tax-15 %                $.10.05
 Total(icl tax)          $.77.05

 Customer Paid           $.80.00
