The following code demonstrates inheritance and method overriding. The Dog and Cat classes inherit from Animal and override the describe() method. What is the complete output when this code is executed?   class Animal:    def __init__(self, name=”unknown”):        self.name = name        def describe(self):        return f”An animal named {self.name}.”class Dog(Animal):    def __init__(self, name=”unknown”, breed=”mixed”):        super().__init__(name)        self.breed = breed        def bark(self):        return f”{self.name} the {self.breed} barks loudly.”        def describe(self):        return f”A {self.breed} dog named {self.name}.”class Cat(Animal):    def __init__(self, name=”unknown”, color=”gray”):        super().__init__(name)        self.color = color        def meow(self):        return f”{self.name} the {self.color} cat meows.”animal = Animal(“Creature”)dog = Dog(“Buddy”, “Golden Retriever”)cat = Cat(“Whiskers”, “orange”)print(animal.describe())print(dog.describe())print(dog.bark())print(cat.describe())print(cat.meow())

The following code shows the definition for the class Pizza. This class has multiple functions, including some functions that use @staticmethod and @classmethod decorators. However, some lines contain syntax or logical errors. Identify ALL line numbers that contain errors and briefly explain what is wrong with each line   1.  class Pizza:2.      menu_items = []3.      total_orders = 04.      5.      def __init__(self, size, toppings):6.          self.size = size7.          self.toppings = toppings8.      9.      @staticmethod10.     def calculate_price(self, size):11.         prices = {“small”: 8, “medium”: 12, “large”: 16}12.         return prices.get(size, 0)13.     14.     @classmethod15.     def add_to_menu(name, price):16.         cls.menu_items.append({“name”: name, “price”: price})17.     18.     @classmethod19.     def get_total_orders(cls):20.         return self.total_orders21.     22.     @staticmethod23.     def is_valid_size(size):24.         return size in [“small”, “medium”, “large”]25. 26. pizza1 = Pizza(“large”, [“pepperoni”, “cheese”])27. print(Pizza.calculate_price(“medium”))28.

The following code contains definitions for classes Device and Speaker. In this code, the Speaker class is the child of the Device class, and uses inheritance techniques in its implementation. However, the implementation has logical or syntax errors. Identify ALL line numbers that contain errors and briefly explain what is wrong with each line. 1.  class Device:2.      def __init__(self, name):3.          self.name = name4.     5.      def make_sound():6.          print(“Some generic sound”)7. 8.  class Speaker(Device):9.      def __init__(self, name, breed):10.         super().__init__(self, name)11.         self.breed = breed12.     13.     def make_sound(music_name):14.         super.make_sound()15.         print(f”Music started: {music_name}”)16. 17. my_speaker = Speaker(“Buddy”, “Golden Retriever”)18. my_speaker.make_sound(“Never Gonna Give You Up”)
