Yes, it should. I'm not sure what you mean when you say "more
precisely, when there is no process running in that window." In
general, when I run C-c C-c before I start the interpreter with a
C-c !, there is no '*Python*' buffer. The C-c C-c command creates
a '*Python Output*' buffer to display any output, but it doesn't start
a Python shell and doesn't create a '*Python*' buffer. When the '*Python*'
buffer already exists, then C-c C-c uses that buffer instead of the
'*Python Output*' buffer, displaying a "# working" message and any
output/errors in the '*Python*' buffer.
Thus, C-c C-c always works for me (GNU Emacs 20.3.1,
python-mode 3.105, Red Hat Linux with kernel 2.2.5-15), it just
behaves slightly differently depending upon whether I have a
'*Python*' buffer open already. Perhaps you could explain
in more detail how to evoke this problem.

Hm. I hadn't thought of that. I suppose that for me, this is like
Python whitespace issue. I've never had a problem with it.
