I have python mode py-version "5.1.0" on my machine. My guess is that python-mode changed the session prompt in such a way that Babel can not tell when execution has completed. I have the following in my *Python* session buffer after execution [1], what are the contents of your *Python* session buffer after you have C-g'd out of the loop?
