Is it possible to change stdout after starting something as a background application in the command line?

Say I run test.py:

import time

while True:
    print "Hello"
    time.sleep(1)

and then do:

$ python test.py &

Can I redirect the output to /dev/null somehow?

Not unless you taught the program to do so somehow (say, on receipt of a particular signal such as SIGUSR1 it reopens sys.stdout and sys.stderr on /dev/null). Otherwise, once it's been started you have very little control over it.
