在Python中使用RotatingFileHandler按日期旋转日志

Question

I am looking for a method which will allow me to rotate the logs at midnight instead of rotating them using the maxBytes parameter.

So far, the logs are rotated when a file reaches 10MB.

LOG_PATH = os.path.join(APPLICATION_PATH, "log\\My_log.log")

my_handler = RotatingFileHandler(LOG_PATH, mode='a', maxBytes=10000000, backupCount=20)
logger.addHandler(my_handler) 

Is there a way of passing a date parameter to RotatingFileHandler() so that instead of rotating after the file reaches 10MB it will rotate the file at midnight ?

使用TimedRotatingFileHandler ：

my_handler = TimedRotatingFileHandler(LOG_PATH, when='midnight', backupCount=20)
