Problem with Emacs mode, at start only

Hi, Francois.  Adding something like the following code to your .emacs
file might go some way to solving your problem.  Actually, it's been a
bit of a pain for me, too, but I didn't realize it until I read your
post.  :)

(add-hook 'python-mode-hook '(lambda ()
			       (save-window-excursion
				 (py-shell)
				 (local-unset-key "\C-c\C-c")
				 (local-set-key "\C-c\C-s"
						'comint-interrupt-subjob))))

This automatically starts the python shell whenever you go into
python-mode, and rebinds what used to be C-c C-c to C-c C-s.  You will
still have to switch to the python shell in order see the results of
executing your code, though.

Hope this helps.
Alex.
