Thanks for the help.  I like your version and would very much like to
use it.
The "save-restriction" is a nice touch too.

I copied your version essentially verbatim into my .emacs....

   (defun cs-py-comment-region(beg end) (interactive "r")
    (save-restriction
      (narrow-to-region beg end)
      (py-comment-region)
      (delete-trailing-whitespace)))

It give me the following error message when I hightlight a region with
mouse
and then type C-ac which is setup to call this function....

save-restriction: Wrong number of arguments: (lambda (beg end
&optional arg) "Like `comment-region' but uses double hash (`#')
comment starter." (interactive "r
P") (let ((comment-start py-block-comment-prefix)) (comment-region beg
end arg))), 0

Do you know what this error means and how to fix?

Thanks again,

Chris
