Thank you Chris Matthews for your reply. I'm working on a online examination system. I could able to generate some random questions from a data base containg hundreds of questions. So when ever a user answer and submit those random questions a dictionary contating a "Question_id and Answer" pair will be send as a request.
Now I have to get those dictionary keys first, i.e., the Question_id and then I have to cross check the values i.e., the values with the database values.
