Hi, I've taught a python course with some positive results to high school students with zero experience in programming. Now I am making these course materials (slides in English and lecture videos in Cantonese) freely available as a contribution back to the community (http://www.istudycenter.org/summercourses/programming-for-kids/python-materials).
Hope you find them useful :-) -- https://mail.python.org/mailman/listinfo/python-list
