What are some examples of polymorphism in Python?

Polymorphism in Python allows methods to do different things based on the object it is acting upon. For example, you can have a method called draw() that behaves differently for different shapes like circles and squares.

Can you show me a code example?

Sure! Here's a simple example:

class Shape:
    def draw(self):
        pass

class Circle(Shape):
    def draw(self):
        return 'Drawing a circle'

class Square(Shape):
    def draw(self):
        return 'Drawing a square'

shapes = [Circle(), Square()]
for shape in shapes:
    print(shape.draw())

This will output:

Drawing a circle
Drawing a square

What if I want to add another shape?

You can simply create a new class for the shape and implement the draw() method. For example, if you want to add a triangle:

class Triangle(Shape):
    def draw(self):
        return 'Drawing a triangle'

Then, just add an instance of Triangle to your shapes list.

That's really helpful, thanks!
