python实现log日志的示例代码

源代码：

# coding=utf-8import loggingimport osimport time

LEVELS={'debug':logging.DEBUG,\\ 'info':logging.INFO,\\

'warning':logging.WARNING,\\ 'error':logging.ERROR,\\ 'critical':logging.CRITICAL,}

logger=logging.getLogger()level='default'

def createFile(filename):

path=filename[0:filename.rfind('/')] if not os.path.isdir(path): os.makedirs(path)

if not os.path.isfile(filename):#创建并打开⼀个新⽂件

fd = open(filename,mode='w',encoding='utf-8') fd.close()class MyLog:

log_filename='E:/quality/it/pyrequest-master/log/itest.log' err_filename='E:/quality/it/pyrequest-master/log/err.log' dateformat='%Y-%m-%d %H:%M:%S'

logger.setLevel(LEVELS.get(level,logging.NOTSET)) createFile(log_filename) createFile(err_filename)

#注意⽂件内容写⼊时编码格式指定

handler=logging.FileHandler(log_filename,encoding='utf-8') errhandler=logging.FileHandler(err_filename,encoding='utf-8') @staticmethod #静态⽅法

def debug(log_message): setHandler('debug')

logger.debug(\"[DEBUG \"+getCurrentTime()+\"]\"+log_message) removerhandler('debug') @staticmethod

def info(log_message): setHandler('info')

logger.info(\"[INFO \"+getCurrentTime()+\"]\"+log_message) removerhandler('info')

@staticmethod

def warning(log_message): setHandler('warning')

logger.warning(\"[WARNING \"+getCurrentTime()+\"]\"+log_message) removerhandler('warning') @staticmethod

def error(log_message): setHandler('error')

logger.error(\"[ERROR \"+getCurrentTime()+\"]\"+log_message) removerhandler('error') @staticmethod

def critical(log_message): setHandler('critical')

logger.critical(\"[CRITICAL \"+getCurrentTime()+\"]\"+log_message) removerhandler('critical')

# logger可以看做是⼀个记录⽇志的⼈，对于记录的每个⽇志，他需要有⼀套规则，⽐如记录的格式（formatter），# 等级（level）等等，这个规则就是handler。使⽤logger.addHandler(handler)添加多个规则，# 就可以让⼀个logger记录多个⽇志。def setHandler(level): if level=='error':

logger.addHandler(MyLog.errhandler)

#handler=logging.FileHandler(log_filename) #把logger添加上handler

logger.addHandler(MyLog.handler)def removerhandler(level): if level=='error':

logger.removeHandler(MyLog.errhandler) logger.removeHandler(MyLog.handler)def getCurrentTime():

return time.strftime(MyLog.dateformat,time.localtime(time.time()))if __name__==\"__main__\":

MyLog.debug(\"This is debug message\") MyLog.info(\"This is info message\")

MyLog.warning(\"This is warning message\") MyLog.error(\"This is error message\") MyLog.critical(\"This is critical message\")

以上这篇python实现log⽇志的⽰例代码就是⼩编分享给⼤家的全部内容了，希望能给⼤家⼀个参考，也希望⼤家多多⽀持。
