In the example below, you will create a class Cube that inherits from Square and extends the functionality of .area() (inherited from the Rectangle class through Square) to calculate the surface area and volume of a Cube instance: Now that you’ve built the classes, let’s look at the surface area and volume of a cube with a side length of 3: Caution: Note that in our example above, super() alone won’t make the method calls for you: you have to call the method on the proxy object itself. # Here we declare that the Square class inherits from the Rectangle class, 'RightPyramid' object has no attribute 'height'. __del__ is a special method of a destructor class, and “del” is used to destroy a variable defined in the python environment.

In the derived or child class has its, So, now, if we only create an object of the derived class, we still have all the access to, Inheritance is the concept in object-oriented programming in which a, In this example, a Rectangle is a superclass, and Square is a subclass because.
