Version Control and code sharing

I never used version control systems. I realized that all serious developers use them.
I have used in my job SVN but after a research and some trials I decided to use Mercurial.

From now on I will host all the code I write ti bitbucket so it will be available to everyone ( including me , i.e. I had several personals projects or projects from university that are lost somewhere in a back up DVD or completely lost).

I started by adding a test GUI python program ( no functionality, just for learning ).
