Homework

1. Name your homework APR11_supermarket_hw, please submit by next Monday.
2. Homework: The following code exists in our old grocery_shopping_cart file that we want to replace:

   if selection == "99":
       break
   elif selection in items_inventory.keys():
       print(f"You have purchased {items_inventory[selection]} for ${items_price[selection]}")
           total_cost += items_price[selection]
       shopping_cart.append(items_inventory[selection])
   else:
       print("Invalid selection, please try again.")

   How can we add this to our while loop inside our ShoppingCartApplication class? Remember, all you need to use is:
   – self.menu_items dictionary attribute to get item names and prices
   – self.menu attribute to help see what each price and name means
