"Is" function is use to compare the id of each object.
The == operator compares the values of both the operands and checks for value equality.
Whereas( is) operator checks whether both the operands refer to the same object or not.
This. Code can be written as print(id(lap_list)==id(nap_list))
Why is appearing a mistake in the next code?
def __init__(self, toppings):
self.toppings = toppings
if topping == "pineapple":
raise ValueError("No pineapples!")
ingredients = ["cheese", "onions", "spam", "pineapple"]
if all(Pizza.validate_topping(i) for i in ingredients):
pizza = Pizza(ingredients)
