Question

在Python中，使用

import logging
logging.basicConfig(filename="logname",
                    filemode='a',
                    format='%(asctime)s,%(msecs)03d %(name)s %(levelname)s %(message)s',
                    datefmt='%D %H:%M:%S',
                    level=logging.DEBUG)

logging.getLogger().addHandler(logging.StreamHandler())
logging.info("=================================================")
logging.info("starting execution")

我能够在日志文件中正确地记录格式：

03/30/18 12:52:08,231 root INFO =================================================
03/30/18 12:52:08,232 root INFO starting execution

不幸的是，对于控制台，没有遵循格式：

Connected to pydev debugger (build 173.4674.37)
=================================================
starting execution

我需要编写什么才能使控制台输出格式化？

python文档中的这个例子看起来就是诀窍https://docs.python.org/2/howto/logging-cookbook.html#logging-to-multiple-destinations

import logging
logging.basicConfig(filename="logname",
                    filemode='a',
                    format='%(asctime)s,%(msecs)03d %(name)s %(levelname)s %(message)s',
                    datefmt='%D %H:%M:%S',
                    level=logging.DEBUG)

console = logging.StreamHandler()
console.setLevel(logging.DEBUG)
# set a format which is simpler for console use
formatter = logging.Formatter('%(asctime)s,%(msecs)03d %(name)s %(levelname)s %(message)s')
# tell the handler to use this format
console.setFormatter(formatter)
# add the handler to the root logger
logging.getLogger('').addHandler(console)

logging.info("=================================================")
logging.info("starting execution")

提供以下控制台输出

2018-03-30 19:15:00,940,940 root INFO =================================================
2018-03-30 19:15:07,768,768 root INFO starting execution

在没有格式化的情况下发生Std.out的附加日志记录
