def get_balance(self): return self.__balance

def area(self): return self.width ** 2 In this example, the Square class overrides the area method of the Rectangle class. Encapsulation is the concept of hiding the internal details of an object from the outside world and only exposing a public interface through which other objects can interact with it. python 3 deep dive part 4 oop

class Square(Rectangle): def __init__(self, side_length): super().__init__(side_length, side_length) def get_balance(self): return self

my_car = Car("Toyota", "Corolla", 2015) This creates a new object called my_car from the Car class, with the specified attributes. Here's an example of method overriding in Python

Here's an example of method overriding in Python 3:

def deposit(self, amount): self.__balance += amount In this example, the BankAccount class has a private variable __balance that can only be accessed through the get_balance method. In this article, we've covered the basics of Object-Oriented Programming (OOP) in Python 3, including classes, objects, inheritance, polymorphism, and encapsulation. We've also provided examples of how to implement these concepts in Python 3.

In Python 3, encapsulation can be achieved using private variables and methods, which are denoted by a double underscore prefix.
