Thank you, Kent In fact, I followed the page you posted, but it seems not working at all, maybe due to version or so.
But good hints, and I find it in Python Documentation 2.3.4. http://www.python.org/doc/2.3.4/lib/node301.html After some trials, I find the minimal ways to meet my need. Just define two handler, one through FileHandler and the other through StreamHandler. from logging import * import sys logger=getLogger('application') formatter=Formatter('%(asctime)s %(levelname)s %(message)s') handler1=FileHandler('application.log','w') handler1.setFormatter(formatter) handler2=StreamHandler(sys.stdout) handler2.setFormatter(formatter) logger.addHandler(handler1) logger.addHandler(handler2) logger.setLevel(DEBUG) logger.error('We have a problem.') logger.info('And some information.')
