Python中logging模块的用法实例

import logging 
import os 
 
log = logging.getLogger() 
formatter = logging.Formatter('[%(asctime)s] [%(name)s] %(levelname)s: %(message)s') 
 
 
stream_handler = logging.StreamHandler() 
file_handler = logging.FileHandler(os.path.join("c:\\", "analysis.log")) 
 
 
file_handler.setFormatter(formatter) 
stream_handler.setFormatter(formatter) 
 
 
log.addHandler(file_handler) 
log.addHandler(stream_handler) 
log.setLevel(logging.DEBUG) 
 
 
log.warn("a warning %s " % "c:\\")
