## 日志 ##

日志级别：logging.debug()

logging.info()

logging.warning()

logging.error()

logging.critical()

logging.basicConfig(level=logging.DEBUG　　设置级别

,filename="logger.log"　　写进文件

,filemode="w"　　　　　　模式

,format="%(sactime)s"　　格式

日志在屏幕和文件只能选一个输出显示

logger=logging.getlogger()　　不设参数默认根用户，设参数为子用户

fh=logging.FileHandler("test\_log")　　向文件发送日志

ch=logging.StreamHandler()　　向屏幕发送日志

fm=logging.Formatter("%(asctime)s %(message)s")

fh.SetFormatter(fm)

ch.setFormatter(fm)

logger.addHandler(fh)

logger.addHandler(ch)

logger.setlevel("DEBUG")　　级别相关设定

logger.debug("hello")

logger.info()

logger.warning()

logger.error()

logger.critical()

logger=logger()

注意点：1、起用户名字，名字是唯一的，重复的话指的是同一个对象

2、创建logger对象，如果是子对象则会看父对象有无工作，父对象也向文件或屏幕输出工作，会多输出一次
