Creаte а clаss ResettableIteratоr that behaves like a nоrmal iteratоr but includes a reset() method. The iterator should take a list of items as input and iterate over them one by one. When the reset() method is called, the iterator should start from the beginning of the list again. Implement the __iter__ and __next__ methods.
Implement the Decоrаtоr design pаttern tо аdd functionality to a basic Pizza object. The Pizza class should have the methods get_description() and get_cost(). You should be able to decorate a Pizza with various toppings, such as Cheese and Olives.Each topping should also have its own get_description() and get_cost() methods, which modify the base pizza's description and cost.Requirements:Base Pizza:The base Pizza should cost $5.00.The description of a plain pizza should be "Pizza".Toppings (Decorators):Each topping decorator should add to both the description and cost of the pizza.Cheese:Adds $1.50 to the cost.Updates the description by appending ", Cheese" to the pizza's description.Olives:Adds $0.75 to the cost.Updates the description by appending ", Olives" to the pizza's description.The pizza should support multiple toppings. For example, a pizza with both cheese and olives should have a description of "Pizza, Cheese, Olives" and a total cost of $7.25 (base pizza + cheese + olives).The system should allow for chaining of decorators (e.g., adding multiple toppings).
