Create a new file that builds a shopping list from a user. There should be a input query that asks the user to list an item and the number of those items. Two lists should be built that reflects the items on the list and the number of each items that are to be purchased. The list should build until the user is done. b. Call up your function grocery_cost to check the stock and build your total cost. Your program should let the user know if the items they want are in stock. If there is not enough stock, your program should let the user know that and offer them the number that are in stock. You will need to edit your grocery_cost function to reflect that a number of items will be selected instead of just one. c. Call up your stock_check function and print items that need restocking

Check the output
