#  logger.info('This is an info message')
#  Logger().info() --> ._log()  然后 -> .makeRecord()  # makeRecord 生成LogRecord对象,就是一条日志记录的对象
#  然后调用 Logger().handle(record)  ---> .callHandlers(record) 里面循环执行 hdlr.handle(record), 这个hdlr 就是MidnightRotatingFileHandler对象，
#  找MidnightRotatingFileHandler的 父类 handle方法的实现，一直找到Handler类里的下面这个

# def handle(self, record):
#     """
#     Conditionally emit the specified logging record.

#     Emission depends on filters which may have been added to the handler.
