Is there a course on udacity that teaches you how to build apps on Google App Engine? They do have one on building web apps but it does not specify which platform they use (if any).
The web application course is taught by Steve Huffman (creator of Reddit) and the first lesson is actually to write a "Hello World" script and publish it on App Engine.
For anyone new to Python, I highly recommend Udacity. It's still a little unbelievable to me that it's free.
*edit: I should have mentioned that this course uses app engine throughout it's entirety. Not just the first lesson :)
