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
Types of Loop
Loops are the elements of programming in which a part of code is repeated a particular number of times. Loop executes the series of statements many times till the conditional statement becomes false.
Loops
Any task which is repeated more than one time is called a loop. Basically, loops can be divided into three types as while, do-while and for loop. There are so many programming languages like C, C++, JAVA, PYTHON, and many more where looping statements can be used for repetitive execution.
While Loop
Loop is a feature in the programming language. It helps us to execute a set of instructions regularly. The block of code executes until some conditions provided within that Loop are true.
