I have file dessert.py which has the methods can_combine and combine. I need to apply those two methods in my dessertshop.py file inside the __add__ method in my Order class to combine all like-items such as my my_cookie = Cookie("oatmeal raisin", 2, 3.45) and my_cookie = Cookie("oatmeal raisin", 4, 3.45) and only add the combined dessert to the list self.order. So those two Cookie objects should only be one my_cookie = Cookie("oatmeal raisin", 6, 3.45), the rest of the items should be added to the list since they don't have a similar object. Please let me know if I need to add more information.
