Python, want logging with log rotation and compression

import gzip
import os
import logging
import logging.handlers

class GZipRotator:
    def __call__(self, source, dest):
        os.rename(source, dest)
        f_in = open(dest, 'rb')
        f_out = gzip.open("%s.gz" % dest, 'wb')
        f_out.writelines(f_in)
        f_out.close()
        f_in.close()
        os.remove(dest)

logformatter = logging.Formatter('%(asctime)s;%(levelname)s;%(message)s')
log = logging.handlers.TimedRotatingFileHandler('debug.log', 'midnight', 1, backupCount=5)
log.setLevel(logging.DEBUG)
log.setFormatter(logformatter)
log.rotator = GZipRotator()

logger = logging.getLogger('main')
logger.addHandler(log)    
logger.setLevel(logging.DEBUG)
