Python programming classes for children

[beliavsky at aol.com]

My 11yo son is taking the online class "Intermediate Programming with Python" http://www.artofproblemsolving.com/school/course/catalog/python2 offered by the Art of Problem Solving company (AoPS). Classes meet for 1.5 hours a week for 12 weeks. During the classes the instructor "lectures" (types into a console -- there is no sound) and students type answers to questions. There are weekly programming assignments. AoPS is a U.S. company whose focus is preparing students for math competitions.

Are there other groups offering Python courses for pre-college students?
