class LoggerWriter:
    def __init__(self,logger,level):
        self.logger = logger
        self.level = level

    def write(self,message):
        if message != '\n':
            self.logger.log(self.level,message)

def main():
    logging.basicConfig(level=logging.DEBUG)
    logger = logging.getLogger("demo")
    info_fp = LoggerWriter(logger,logging.INFO)
    debug_fp = LoggerWriter(logger,logging.DEBUG)
    print >> info_fp,"An INFO message"
    print >> debug_fp,"A DEBUG message"

if __name__ == "__main__":
    main()

运行时,脚本会打印：

INFO:demo:An INFO message
DEBUG:demo:An DEBUG message
