Why on earth are you *specifying* c:\python25 as the
directory for this file? It's automatically created

suffix & prefix.
ie, unless you have some specific need in mind, just use:
temp = tempfile.NamedTemporaryFile ()

The main stumbling block here is that you're not posting
code you're running, but fragments of code which may or
may not exist in your source. What is tn? What have x
and y to do with anything? What is find_file? And so on.
As far as I can tell you're trying to create a temporary
file, pass its name to another process which writes to
it. You then, in the first process, read the results of
the second process. Is that right?
At the very least, please cut-and-paste a session from
the console which is running the program so that the traceback
