| Python 2.x is not that different from Python 3.0. You might want to start learning with it because there are A LOT more resources on the net about Python 2.x than 3.0. It's not compatible but I'm sure beginners program aren't complicated enough that it would be a problem.
Anyway, there was some list somewhere of the differences in 3.0, I'm sure you can find it pretty easily and then convert whatever program you wrote during your learning if you really want to keep them. |
