If they are python functions, this hack should work...

import sys

class NullWriter(object):
    def write(self, arg):
        pass

def testfunc():
    print "this is a test"

nullwrite = NullWriter()
oldstdout = sys.stdout
sys.stdout = nullwrite  # disable output
testfunc()
sys.stdout = oldstdout  # enable output
testfunc()
