(I'm not sure path is the right word here, really, but never mind...)

if you're talking about things that Python prints to stderr, all you need
to do is to replace sys.stderr with something more suitable:
sys.stderr = open("/dev/null", "w")
or, more portable:
def write(self, s):
sys.stderr = NullDevice()
if you want to redirect both things printed via sys.stderr and things
printed to stderr at the C level, you need to redirect the STDERR file
handle. here's one way to do that:
import os, sys
err = open('/dev/null', 'a+', 0)
hope this helps!
