python打印日志到标准输出

 

import logging  
  
  
logging.basicConfig(stream=sys.stdout, level=logging.DEBUG, datefmt='%Y-%m-%d:%H:%M:%S', format='%(asctime)s,%(msecs)d [PID:%(process)d] [%(threadName)-12.12s] %(levelname)-5.5s [%(filename)s:%(lineno)d] --> %(message)s')
logger = logging.getLogger(__name__)    
  
logger.info('start to work. name:%s','kanpiaoxue')

 

 如果不指定 stream=sys.stdout ，python的log会默认打印到标准错误输出。
