import logging

s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
s.bind(('', 8888))
while True:
	data, addr = s.recvfrom(2048)
	data.rstrip('\x00')
	syslog_logger.debug(data)
#	print data
	

1. 定义 log.py

import logging
import logging.handlers

LOG_FILENAME = 'jd-assistant.log'

logger = logging.getLogger()

def set_logger():
    logger.setLevel(logging.INFO)
    formatter = logging.Formatter('%(asctime)s %(levelname)s: %(message)s')

    console_handler = logging.StreamHandler()
    console_handler.setFormatter(formatter)
    logger.addHandler(console_handler)

    file_handler = logging.handlers.RotatingFileHandler(
        LOG_FILENAME, maxBytes=10485760, backupCount=5, encoding="utf-8")
    file_handler.setFormatter(formatter)
    logger.addHandler(file_handler)

set_logger()

2. 使用

from log import logger

class AsstException(Exception):

    def __init__(self, message):
        super().__init__(message)
        logger.error(message)
