In the main function, we have declared a list that has two objects in it. The first object is a Rectangle with width 6 and height 10. The second object is a Circle of radius 7.

The getArea() method returns the area of the respective shape. This is Polymorphism: having specialized implementations of the same methods for each class.

class Shape:
    def __init__(self):  # initializing sides of all shapes to 0
        self.sides = 0

    def getArea(self):
        pass


class Rectangle(Shape):  # derived from Shape class
    # initializer
    def __init__(self, width=0, height=0):
        self.width = width
        self.height = height
        self.sides = 4

    # method to calculate Area
    def getArea(self):
        return (self.width * self.height)


class Circle(Shape):  # derived from Shape class
    # initializer
    def __init__(self, radius=0):
        self.radius = radius

    # method to calculate Area
    def getArea(self):
        return (self.radius * self.radius * 3.142)


shapes = [Rectangle(6, 10), Circle(7)]
print("Area of rectangle is:", str(shapes[0].getArea()))
print("Area of circle is:", str(shapes[1].getArea()))
