help, I need answers for my assignment Problem 2 (Using the menu and printing an invoice)Write a program called a2_p2.py where you will modify your code from Problem 1 so thatcustomers can select products from the menu. Copy your solution from the previous part intothe new file (a2_p2.py). Do not overwrite your previous solution, as the TAs will want to seethem both.The user should make their selection by entering the corresponding number. It is possible that theuser will enter any type of data, including text, floating point numbers, negative numbers,etc.. Invalid selections should be handled with a suitable error messages and the menu shouldbe repeated (see sample outputs below). Once the customer has selected a product, the programshould ask how many of that product the customer would like. Your program must make sure thatselected products are available in stock, otherwise it should generate error messages and the menushould be repeated. After every valid selection current total should be printed and the stock shouldbe updated (see sample outputs below).Following this, the program will ask whether the user wants to continue and see the invoice, orcancel the transaction. If user wants to continue it should provide the user with their receipts(subtotal, tax (13% of the subtotal) and the total cost of the order). Otherwise it should print amessage and terminates (see sample outputs below).Sample output - 1:. it will first print the similar content as shown in the previous part and then==========:=========Please select the item you wantto buy from the following menu:1.
