[IAEP] Nice tool for learning Python

[STEPHEN JACOBS]

If you haven't seen Teagueduino yet, it's worth a look as a system that does a good job of making the invisible visible, especially parts of the programming interface that show you the signals/voltages in the chip being set high or low when things run.  The two pictures of the editor in the article below show some of this.

The programmers can see the changes in the already visible objects. (That is partly the point in how they are designed for beginners.)
