class Rectangle: def __init__(self, width, height): self.width = width self.height = height
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.
Here's an example of method overriding in Python 3: python 3 deep dive part 4 oop
class Car: def __init__(self, make, model, year): self.make = make self.model = model self.year = year
def charge(self): print("Charging...") In this example, the ElectricCar class inherits from the Car class using the (Car) syntax. The super().__init__ method is used to call the __init__ method of the parent class. class Rectangle: def __init__(self, width, height): self
class Square(Rectangle): def __init__(self, side_length): super().__init__(side_length, side_length)
Here's an example of a simple class in Python 3: Here's an example of method overriding in Python
class BankAccount: def __init__(self, balance): self.__balance = balance
