my_car = Car("Toyota", "Corolla", 2015) This creates a new object called my_car from the Car class, with the specified attributes.

Method overriding is when a subclass provides a different implementation of a method that is already defined in its superclass.

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. python 3 deep dive part 4 oop

class BankAccount: def __init__(self, balance): self.__balance = balance

print(my_car.make) # Output: Toyota my_car.honk() # Output: Honk honk! Inheritance is a fundamental concept in OOP that allows one class to inherit the attributes and methods of another class. The class that is being inherited from is called the parent or superclass, and the class that is doing the inheriting is called the child or subclass. my_car = Car("Toyota", "Corolla", 2015) This creates a

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.

Here's an example of method overriding in Python 3: In this article, we've covered the basics of

def honk(self): print("Honk honk!") In this example, Car is a class that has three attributes: make , model , and year . The __init__ method is a special method that is called when an object is created from the class. It initializes the attributes of the class.
