Hi, Alexander

You can use something like this in your dot emacs file:

(defun my-python-hook ()
  (define-key python-mode-map "\C-m" 'newline-and-indent))

(add-hook 'python-mode-hook 'my-python-hook)

or a bit shorter version

(add-hook 'python-mode-hook
          '(lambda ()
              (define-key python-mode-map "\C-m" 'newline-and-indent)))

Ruslan
