It does when you call it interactively. When you call it programmatically, you need to specify the START and END arguments: (region-beginning) and (region-end), respectively. Your cs-py-comment-region function should take 2 arguments, provide a way for them to be specified when it's called interactively, and pass the region bounds to py-comment-region: (defun cs-py-comment-region (beg end) (interactive "r") (py-comment-region beg end) ...) -- Kevin Rodgers
