Python logging管理不同级别log打印和存储实例


            Python内置模块logging管理不同级别log打印和存储，非常方便，从此告别了使用print打桩记录，我们来看下logging的魅力吧





import logging 

 

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 = './logcheck.log', 

          filemode = 'w') 

 

############################################################################### 

#define one StreamHandler, set the log mode 

console = logging.StreamHandler() 

console.setLevel(logging.INFO) 

formatter = logging.Formatter('%(name)-12s: %(levelname)-8s %(message)s') 

console.setFormatter(formatter) 

logging.getLogger('').addHandler(console) 

############################################################################### 

 

filePath = r'C:\ddms.bat' 

 

logging.error('Open file failed!') 

logging.warn('sort mode disabled') 

logging.debug('%s' % filePath) 

logging.info('xml file generated successfully!') 



运行结果：





root    : ERROR  Open file failed! 

root    : WARNING sort mode disabled 

root    : INFO   xml file generated successfully!
