Inheritance is a mechanism in OOP that allows one class to inherit the properties and behavior of another class. The child class inherits all the attributes and methods of the parent class and can also add new attributes and methods or override the ones inherited from the parent class. my_car = Car("Red", "Toyota", "Camry") print(my_car
