Fredrik already said this, but you didn't appear to read it, so I'll
say it too.
Look at the second to last line of your traceback.  The command being
executed is:
     out_file = open(out_filename)
what you probably meant to have there was:
     out_file = open(out_filename,"w")

The problem most likely has nothing to do with mysterious backslash
doubling.
