No, changing sys.stdout won't affect that sort of output.
On Unix, the easiest way would be to do the redirection
outside of the program, e.g. using the shell.

If you have to be able to redirect from within the
program, you could try, in C:

   freopen(filename, "w", stdout);

or in Python:

   import posix, sys
   f = open(filename, "w")
   sys.stdout.flush()
   posix.dup2(f.fileno(), 1)
