A. Shaw [Learn Python the Hard Way](http://learnpythonthehardway.org/). All the codes are written in both Python2(2.7.5) and Python3(3.3.2). The best way to check my solution step by step is to use `git log` command. For instance, ``` sh $ git log -p Python2/ex04.py ``` Alternatively you can browse the history of any file on Github to see the change of it. If you got a better answer, welcome to comment the code and share your version! ### Screenshots ### 1. The final web page game(ex52): ![](./media/game.png) 2.
