# Polymorphism = Greek word that means to "have many forms or faces" # Poly = Many # Morphe = Form # TWO WAYS TO ACHIEVE POLYMORPHISM # 1. Inheritance = An object could be treated of the same type as a parent class # 2. "Duck typing" = Object must have necessary attributes/methods from abc import ABC, abstractmethod class Shape(ABC): @abstractmethod def area(self): pass class Circle(Shape): def __init__(self, radius): self.radius = radius def area(self): return 3.14 * self.radius ** 2 class Square(Shape): def __init__(self, side): self.side = side def area(self): return self.side ** 2 class Triangle(Shape): def __init__(self, base, height): self.base = base self.height = height def area(self): return self.base * self.height * 0.5 class Pizza(Circle): def __init__(self, topping, radius): super().__init__(radius) self.topping = topping shapes = [Circle(4), Square(5), Triangle(6, 7), Pizza("pepperoni", 15)] for shape in shapes: print(f"{shape.area()}cm²")
