Python 3 Deep Dive Part 4 Oop May 2026

Here's an example of inheritance in Python 3:

class Car: def __init__(self, make, model, year): self.make = make self.model = model self.year = year python 3 deep dive part 4 oop

class ElectricCar(Car): def __init__(self, make, model, year, battery_size): super().__init__(make, model, year) self.battery_size = battery_size Here's an example of inheritance in Python 3:

class Square(Rectangle): def __init__(self, side_length): super().__init__(side_length, side_length) python 3 deep dive part 4 oop

The honk method is an example of a method that can be called on an object of the Car class. To create an object from a class, you use the class name followed by parentheses, like this:

The ElectricCar class also has its own attribute battery_size and method charge . Polymorphism is the ability of an object to take on multiple forms. In Python 3, polymorphism can be achieved through method overriding or method overloading.
