In python, A customer in a store is purchasing items. Write a program, using a while loop, that asks for the price of each item, then displays the subtotal of the sale, the amount of sales tax, and the total when the customer is done entering all the items. Assume the sales tax is 7 percent. The customer should be allowed to enter as many items as they wish. The while loop should terminate when the user hit the key (Return) on the keyboard. (Hint: Use a null or empty string). Optionally, if you would like to round the dollar amount to two decimal places, you can use output formatting construct in your print statement. For example: print("Sales tax: ", format(sales_tax, '.2f')) will round to two decimal places.

Expected Output:

Enter the item price or to end: 22.50 Enter the item price or to end: 1.99 Enter the item price or to end: 45.30 Enter the item price or to end: 70 Enter the item price or to end: 5 Enter the item price or to end: Subtotal of items purchased: 144.79 Sales tax: 10.14 Total of items purchased: 154.93
