Put this in your .emacs:

(defun python-personal-dedent ()
  (interactive)
  (let ((cyclic 'python-indent-line-backward)
        (old (current-indentation)))
    (setq this-command cyclic)
    (python-indent-line-backward)
    (setq last-command cyclic)
    (when (and (> python-indent-list-length 1)
               (= old (current-indentation)))
      (python-indent-line-backward))))

(add-hook 'python-mode-hook
          (lambda ()
            (local-set-key [backtab] 'python-personal-dedent)))
