) Al Shams supermarket is a largest shopping center in Oman for electronic items and home appliance. They want to create invoice for their customer after they supplying the goods. Write a Python program to ask the user to input the purchase amount, customer type ('O': Online or 'F': Offline) for 10 customers and store them in two different lists. The sample input data is shown below. [15 Marks) Purchase Amount=(100, 75, 110,300,150, 400, 200, 100, 140, 100] Customer Type = '0','0"F","0","0","F",0,0") F0 Your program has to do the following tasks. a) Calculate and display the discount for each customer according to the following table and store it in a List Customer Types Purchase Amount Discount Online Customer Purchase Amount < 100 5% of Purchase Amount 100 s Purchase Amount < 200 10% of Purchase Amount 200 s Purchase Amount 15% of Purchase Amount Offline Customer Purchase Amount < 100 5% of Purchase Amount Purchase Amount >= 100 10% of Purchase Amount b) Calculate and display the total amount for each customer and store it in a list according to the following formula Total Amount= Purchase Amount - Discount c) Calculate and display the sales tax for each customer and store it in a list based on the criteria given in the below table. Total Amount Sales Tax Total Amount < 150 1% of Total Amount 150 s Total Amount < 400 2% of Total Amount 400 S Total Amount 3% of Total Amount d) Calculate and display the net purchase amount for each customer and store it in a list according to the following formula Net Purchase amount= Total Amount + Sales Tax e) Calculate and display sum of discount and net purchase amount of all the customers. f) Calculate and display average net purchase amount of online customers. g) Calculate and display number of online customers whose Net purchase amount > 200. h) Calculate and display the maximum net purchase amount
