: or better yet, how do i
: output to both at the same time?

On UNIX:

>>> class tee:
...  def __init__(s, *targets):
...   s.l = targets
...  def write(s, what):
...   for t in s.l:
...    t.write( what )
... 
>>> sys.stdout = tee( sys.__stdout__, open("t1",'w'), open("t2",'w') )
>>> print "works?"
works?
>>> #^D here       
dcalvelo at lael:~/tmp$ cat t1
works?
dcalvelo at lael:~/tmp$ cat t2
works?

Should be portable to win32.
