Okay I'll explain it to you #Create a Pizza class class Pizza: def __init__(self, toppings): self.toppings = toppings @staticmethod # What this does is create a function like def for example without using self, receiving an argument def validate_topping(topping): #What it does here is evaluate if the argument is equal to pineapple if topping == "pineapple": #If it turns out green, it will cause a created error to be thrown that says No pineapple raise ValueError("No pineapples!") else: #Otherwise it will return True return True #Here is where to create a list of ingredients ingredients = ["cheese", "onions", "spam"] #What it will do is iterate the ingredients and pass each ingredient to the validate_topping method and the all function is used to verify if all the ingredients are valid, otherwise it will not print anything if all(Pizza.validate_topping(i) for i in ingredients): pizza = Pizza(ingredients)

Begin down the bottom. You have 3 ingredients. There's an if statement which iterates through those ingredients using "i" and checks them against the method to see if an ingredient is pineapple and raise a value error. If the check is successfully passed I.e. there isn't any pineapple, then the pizza may exist.
