In python, can I redirect the output of print function to stderr?

Question

There\'re lots of print function (python 2.7) in my program. Is there any way I can add a few lines then all the output can be redirected to

Answer 1

In python 2.7 you can do:

import sys

print >> sys.stderr, "To stderr."

Or you can import the behavior from 3.x:

from __future__ import print_function
import sys

print('To stderr.', file=sys.stderr)
