OK, I got your version to work after replacing (py-comment-region)
with  (py-comment-region beg end).  Can you please
explain the (interactive "r") and why you needed to add 2 args to
function at top?..--> (defun cs-py-comment-region(beg end) ..)

It all works but it would be nice to understand it too! 


Thanks again,

Chris
