Felix improved the xturtle python script from part 1 and by randomizing the operators to calculate the forward distance xturtle have to walk.

He also use a try / except section to avoid division by zero errors.

This script will run until stopped by the user.

The whole script can be found in the showmedo wiki.

Really great work! Your videos are informative and fun to program, offering examples you can be impressed by.


Your work is not clear to me... you do not mention what needs to be known... and you assume similar knowledge.

Educating the Open-source Community With Showmedo

Although as important as the software it supports, education and documentation are relatively neglected in the Open-source world. Coders love to code, and explaining how best to use or improve the software tends to be deferred or even sidelined.

At Showmedo we believe the community can play a vital role here and also say thanks for the tools and software that make our lives easier. If you have a piece of software you love or a programming langugage you are enthusiastic about, why not make a screencast showing others how to use it? All the stuff you wish you'd been told, the tips, tricks, insights that would have saved you time and frustration.

Screencasting is easier than you think, and we're happy to help you. You can emailus for advice or just use some of the how-to screencasts on the site. This screencasting learning-pathis a good place to start.
