This is a game for two users who roll 2 dice 5 times. If the total of dice is even the player gains 10 points if it is odd, they lose 5.

If there it is a draw after five rounds then the both users will have to roll one die to determine the winner.

This was a project that i have been doing in computer science which I have now finished if anyone has any suggestions on how I could make it better they will appreciated alot so please suggest how I can improve it.

• The requirements for this game are unclear. Code is always produced to implement a set of well defined and understood requirements, even if you are defining these yourself.


• The code is monolithic, break it down into functions, this is functional decomposition and one of the first skills a programmer needs to learn.


• Use [unittests]2 to automatically test the functionality of those functions, learning to use unittest to engage in Test Driven development will increase your speed of learning at first and make you a far better developer in the long run.


• The code has a very linear flow, programmes should provide flexible flows, break it down into three parts, the setup, the game and the results, wrap these with a menu, to setup, play, see score or exit. Once each part is complete return to the menu loop.


• What is the point of requiring usernames then referring to Players 1 & 2.


• It include lots of pointless functionality such usernames and password from plain text files, capture the names, but do away with the password, security by obscurity offers no security at all.


• It fails if you enter S when first starting, if the file does not exist use Exception Handing to catch this failure, create the blank file and continue. Always attempt to recover from error conditions, make it second nature.


• 
  Always validate user input before proceeding.


• Learn to use the built in language features and libraries, this example plays a similar game with much better usage of Python's built in capabilities. How to make this random number game better?
