A very minimal example:

import sys

class Tee(file):
     others = ()

     def write(self, data):
         file.write(self, data)
         for f in others:
             f.write(data)

tee = Tee(r"c:\temp\output.log","wt")
tee.others = [sys.stdout, sys.stderr]
sys.stdout = sys.stderr = tee

print dir(sys)
sys.foo # error
