This is not the usual behavior, so I presume that you or the code author
(if not the same) have done some non-standard redirection.

If you wrote or have access to the code, write your own (two-line?) version
of raw_input(prompt) using stderror.write(prompt) and return stdin.read().
Or leave stdout alone and use print >> ofile or ofile.write() for the other
stuff. Ofile can easily be selectable as either stdout or something else.
If you don't have the source, make suggestions to the owner/author.

You just did, but part of the definition of 'interactive' is stdout to the
screen or other humanly immediately readable output device ;-)
