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!
