My new non-profit web site is www.getcet.org It's about automatic flow chart generation. I have a program that automatically draws a flow chart next to Python code so that you can see and understand the flow among the lines of Python code. I use a slightly different syntax for flow control than Python does, but the rest is regular Python. I have numerous images to illustrate this. I think it would be a new way to have code that is somewhat self-documenting. It could also help Python be somewhat self-teaching, at least with respect to structured control constructs and how they work.
