Python 3 Deep Dive Part: 4 Oop

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.

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: python 3 deep dive part 4 oop

Method overriding is when a subclass provides a different implementation of a method that is already defined in its superclass. The ElectricCar class also has its own attribute

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. The honk method is an example of a

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 encapsulation in Python 3:

def area(self): return self.width * self.height
