Try looking into logging.Filters:
http://docs.python.org/lib/node358.html

An example:

import logging

class InfoFilter(logging.Filter):
        def filter(self, record):
                return record.levelno == 20

if __name__ == "__main__":
        logger = logging.getLogger()
        hdlr = logging.FileHandler("blah.log")
        hdlr.addFilter(InfoFilter())
        logger.addHandler(hdlr)

        logger.exception("ERROR WILL ROBINSON")

Cheers,
  Aaron
