+## Prerequisites
++ Python 3.x
++ Import of random module
+
+## How the code works
++ Imports random module --> Selective import can be done of random.choice() only
++ 
++ The code uses both for and while loops
++ 
++ The while loop is infinite, and option to exit the program is given to user
++ 
++ User enters question and answer which is accepted via an input()
++ 
++ These input question-answers are stored in a dictionary as key-value pairs (key = question, value = answer)
++ 
++ After input by the user, stored questions are randomly asked to user using random.choice() from random module
++ 
++ Answers are verified by calling the question stored in the dictionary
++
++ Code ends when user inputs "n" to indicate that they wish to exit, or when every question has been asked.
