I don't think anyone's mentioned the python logging package, which is
good for general purpose logging. However, since you want to do this
without changing all your print statements:
In Python 2.x, you can probably reassign sys.stdout. As long as you
aren't outputting anything else to stdout, this should probably work
(lightly tested):
---------------------------------------
import sys
class DummyStdout(object):
def write(self, text):
pass
print "sys.stdout is not redirected"
sys.stdout = DummyStdout()
print "This should not appear"
print "Nor should this"
# Restore the original stdout again
sys.stdout = sys.__stdout__
print "This should appear again now"
----------------------------------------
Instead of the DummyStdout class, you could also try:
sys.stdout = open('NUL', 'w')
I believe NUL is the Windows equivalent of /dev/null, but I'm not an
expert.
In Python 3.0, 'print' is a normal function instead of a keyword, so I
assume you can replace it like this (untested):
----------------------------------------
import __builtin__
def my_print(*args, **kwargs):
pass
__builtin__.print = my_print
----------------------------------------
Hope that helps,
