Sometimes the best way to learn something is to solve problems and learn as you go along!
So far, if the user writes something, it shows up on the screen, but it isn't actually stored. What if you want to actually store data and content in a physical file that can be accessed later!? Well, welcome to FILE HANDLING. It is now time to get really serious about coding in python, and it is suggested that you download your very own installation of python and work with IDLE and a text file. You can continue to work in repl.it as well, but to do so you will need to sign up for a free account with repl.it (this will enable you to work with text and other external files). Note that you may not be allowed internet access in an exam or controlled assessment, which means, geting the hang of coding in IDLE (not in an online browser) is always a good idea.

Please note: The challenges here introduce some basic concepts and the code doesn't necessarily reflect the most elegant solutions. This allows teachers to discuss advantanges and disadvantages of a certain approach with students. As we build up on the challenges, you'll note that the solutions become more elegant as additional programming tools and constructs are introduced
A sample flow chart (design) for this particular challenge could look like:
|Test No.||Description||Test Data(input)||Expected Outcome||Actual Outcome||Further Action?|
