  "If the region is active, shift to the right; otherwise, indent current line."
  (interactive)
  (if (not (region-active-p))
      (indent-for-tab-command)
    (let ((lo (min (region-beginning) (region-end)))
          (hi (max (region-beginning) (region-end))))
      (goto-char lo)
      (beginning-of-line)
      (set-mark (point))
      (goto-char hi)
      (end-of-line)
      (python-indent-shift-right (mark) (point)))))
(define-key python-mode-map [remap indent-for-tab-command] 'my-python-tab-command)
