Python Logging模块的简单使用

#-*- coding: utf-8 -*- 
#!/usr/bin/python

import logging

# create logger
logger = logging.getLogger('simple_example')
logger.setLevel(logging.DEBUG)

# create console handler and set level to debug
ch = logging.StreamHandler()
ch.setLevel(logging.DEBUG)

# create formatter
formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')

# add formatter to ch
ch.setFormatter(formatter)

# add ch to logger
logger.addHandler(ch)

LOG_FILENAME = './logging_example.out'
logging.basicConfig(filename=LOG_FILENAME,level=logging.DEBUG,)

# 'application' code
logger.debug('debug message')
logger.info('info message')
logger.warn('warn message')
logger.error('error message')
logger.critical('critical message')

2种日志显示是一致的，可以单独设置
