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!
