Implement the following class diagrams as follows. Each class implement the Displayable abstract class and the display method should display all the current object's and its superclass object's information. - Define appropriate arguments for__init_ so that all the objects can be created properly. - Define appropriate public properties to access private attributes in other classes. But, you cannot provide a public getter property for any attributes whose types are list or dict, so you must implement _ iter__ and __ next_ methods for them. - Create a main method to test all your classes and their methods thoroughly
