Code in python

# with open("Exam1_Q3.txt", "r") as filestream:
#     for line in range(i,filestream.size()):
#         currentline = filestream[i].split("|")
#         print(currentline)
total_sales = 0
item_name = input("Enter item name: ")
item_quantity = int(input("Enter item quantity: "))
item_price = float(input("Enter item price: "))
item_ex_price = item_quantity * item_price
total_sales+=item_ex_price
#items separated with comma and ends with a new line
data = "Item: %s,Quantity: %d,Price: $%d,Extended Price: $%d\n" % (item_name, item_quantity, item_price, item_ex_price)
print(data)

#save to file
filename = input("Enter file name: ")
f = open(filename, 'w') 
f.write(data)

more_entry = input("Do you have more items to enter? y/n: ")
while more_entry=="y":
    item_name = input("Enter item name: ")
    item_quantity = int(input("Enter item quantity: "))
    item_price = float(input("Enter item price: "))
    item_ex_price = item_quantity * item_price
    total_sales+=item_ex_price
    data = "Item: %s,Quantity: %d,Price: $%d,Extended Price: $%d\n" % (item_name, item_quantity, item_price, item_ex_price)
    f.write(data)
    more_entry = input("Do you have more items to enter? y/n: ")

f.close()

print("Total sales = $%f" % (total_sales))
if(total_sales>100):
    discount = 0.1*total_sales
    print("Discount = $%f" % (discount))
    total_sales -= discount

sales_tax = 0.08*total_sales
print("Tax = $%f" % (sales_tax))
total_sales += sales_tax

print("Total = $%f" % (total_sales))

Sample Console Input/Output

Enter item name: mango
Enter item quantity: 2
Enter item price: 20
Item: mango,Quantity: 2,Price: $20,Extended Price: $40

Enter item name: apple
Enter item quantity: 1
Enter item price: 10
Do you have more items to enter? y/n: n
Total sales = $210.000000
