BK, Khan Academy is the one that has Python. If you can, you should do the Karel assignments, they're super fun and teaches you more about programming than Java.
and I've just finished the StoneMasonKarel code. I'd love feedback, corrections, improvements, or anything!
/*
* File: StoneMasonKarel.java
* --------------------------
* The StoneMasonKarel subclass fully repairs damaged pillars in Karel's world. It does not * place more than one stone on any corner.
