Python logging split between stdout and stderr

Question

Is it possible to have python logging messages which are INFO or DEBUG to go to stdout and WARNING or greater to go to stderr?

Solution

This seems to do what I want:

#!/usr/bin/python
import sys
import logging


class InfoFilter(logging.Filter):
    def filter(self, rec):
        return rec.levelno in (logging.DEBUG, logging.INFO)


logger = logging.getLogger("__name__")
logger.setLevel(logging.DEBUG)

h1 = logging.StreamHandler(sys.stdout)
h1.setLevel(logging.DEBUG)
h1.addFilter(InfoFilter())
h2 = logging.StreamHandler()
h2.setLevel(logging.WARNING)

logger.addHandler(h1)
logger.addHandler(h2)
