创建自定义带时间戳的日志信息

1.datetime中的datetime.datetime.now()生成的时间中自带有毫秒值

# coding=utf-8import time,datetimedef  log(level,con):    try:        with open(‘E:/test.log‘,‘a‘) as f:              # t = time.strftime("%Y-%M-%d  %H:%m:%S")              now = datetime.datetime.now()              con = str(now)  +" "+level+":"+con+"\n"              f.write(con)    except Exception,e:          print e

log("INFO","start test")2.使用logging模块自带的配置

# coding = utf-8

import logging

def f(filename):

logging.basicConfig(level=logging.DEBUG, format=‘%(asctime)s %(filename)s[line:%(lineno)d] %(levelname)s %(message)s‘, \

datefmt=‘%a, %d %b %Y %H:%M:%S‘, \

filename=filename, \

filemode=‘w‘)

return logging

f(filename).debug(‘debug message‘)

f(filename).info(‘info message‘)

f(filename).warning(‘warning message‘)

f(filename).error(‘error message‘)

f(filename).critical(‘critical message‘)
