Restarting the python process in py-shell

Restarting the python process in py-shell

[Neilen Marais]

Hi,

I'm using emacs 23.1.1 (from Ubuntu 10.10) and ipython using
ipython.el. I often need to re-start my interactive python process while
developing and wanted to define a single keybinding for this. I
experimented and found that the functions needed are
comint-quit-subjob and py-shell. I tried M-x comint-quit-subjob M-x
py-shell when in the *Python* buffer, and it worked OK. Then I tried to
make a function to do it, and included the following snippet in my
init.el:

(defun py-shell-restart-process ()
  "Quit and restart current py-shell process"
  (interactive)
  (comint-quit-subjob)
  (py-shell))
(add-hook 'py-shell-hook (lambda () 
(local-set-key "\C-cr" 'py-shell-restart-process)
))

Pressing C-cr kills the process, but for some reason doesn't re-start
the shell process. What am I doing wrong here?

Thanks
