Day 13 - Abstract Classes Explained with Python Implementation

This is Day 13 of our HackerRank 30 Days Coding Challenge. We would be covering Abstract Classes and the implementation in Python.
Abstract classes classes that that cannot be instantiated. They contain one or more abstract method which are declared but not implemented. This means that any class the inherits an abstract class must also implement the abstract methods
