In conclusion, Python 3 provides an excellent platform for implementing OOP principles. By understanding the concepts of classes and objects, inheritance, polymorphism, encapsulation, and abstract classes and interfaces, developers can create robust, scalable, and maintainable software systems. By following best practices and using design patterns, developers can write high-quality code that is easy to understand, modify, and extend. account = BankAccount("1234567890", 1000) print(account

my_electric_car = ElectricCar("Blue", "Tesla", "Model S", 100) print(my_electric_car.color) # Output: Blue my_electric_car.start_engine() # Output: The engine is started. my_electric_car.charge_battery() # Output: The battery is charging. def area(self): return 3

print(rectangle.area()) # Output: 20 print(circle.area()) # Output: 28.26
