I actually tried this time---it works for me. Here's my foo.i file:
------------------------------------------------------
%module Foo

%include exception.i

%{
#include <stdlib.h>
%}

%typemap(in) FILE* {
   if (PyFile_Check($input)) {
       $1 = PyFile_AsFile($input);
   } else {
       SWIG_exception(SWIG_TypeError, "file expected");
   }
}

%inline %{
void test(FILE* out) {
   fprintf(out, "Hello World!\n");
}
%}
------------------------------------------------------

and here's a transcript from my console:

ballabl:~$ swig -python foo.i
ballabl:~$ gcc -shared -I/usr/include/python2.3/ -o _Foo.so foo_wrap.c
ballabl:~$ python
Python 2.3.4c1 (#2, May 13 2004, 21:46:36)
[GCC 3.3.3 (Debian 20040429)] on linux2

ballabl:~$ cat foo.txt
Hello World!
ballabl:~$

you might want to start working from here to get the desired behavior  
for your functions.

Hope this helps,
                Luigi
