Question

can someone please help me? it has to be in python.

Design a class called ItemToPurchase. This class has the following attributes: item_name, item_price, and item_quanity; and has methods for checking the current value of each attribute, a method set_quantity for updating item_quantity value, and a method get_item_cost to return the cost of this item (calculating the product of item_price and item_quantity)

Design a function called take_item for creating an object of ItemToPurchase and returning the created object.

The main function defines a list of ItemToPurchase objects called shopping_cart and then calls the function take_item in a for loop to add multiple items to the shopping_cart list. The main function calls a function show_cart to display all the items in the shopping_cart list, and then calls a function update_cart to update the quantity for an item in the shopping_cart (the item is identified by its item_name attribute). The main function calls a function check_out to calculate and display to total charge for all the items in the shopping_cart.

The following is a sample output from this program.
