Well, you can't keep Python from _executing_ the print statements, but
you can keep it from displaying the results.
Any python object which has a "write" method can be used as target for
the "print" statement, so...
<code>
def test(n):
for i in range(n):
print 'I is =', i
class blackHole(object):
def write(self,*args):
pass
import sys
test(3)
sys.stdout = blackHole()
test(100)
print >> sys.stderr, 'It worked!'
</code>
--
Error messages (which are send to sys.stderr rather than sys.stdout)
will still display normally.
