Sounds like you want to override sys.stdout:
py> class ConditionalWriter(object):
... def __init__(self, outfile, cond=True):
... self.outfile = outfile
... self.cond = cond
... def write(self, text):
... if self.cond:
... self.outfile.write(text)
...
...
py> import sys
py> writer = ConditionalWriter(sys.stdout)
py> sys.stdout = writer
py> print "hi!"
hi!
py> writer.cond = False
py> print "hi!"
py> writer.cond = True
py> print "hi!"
hi!
You probably want to restore sys.stdout when you're done too:
py> sys.stdout = writer.outfile
py> writer.cond = False
py> print "hi!"
hi!
That said, you probably _really_ want the logging module:
