当我使用logging.getLogger(__name__)创建子记录器时，它是否有默认的日志处理程序、日志级别和日志格式？
log = logging.getLogger(__name__)
print(log.__dict__) # this gives attributes dictionary
输出：
{'filters': [], 'name': '__main__', 'level': 0, 'parent': <RootLogger root (WARNING)>, 'propagate': True, 'handlers': [], 'disabled': False, '_cache': {}, 'manager': <logging.Manager object at 0x000001ECCF434520>}
print('value of level attribute (i.e. log level) is: ',log.__getattribute__('level')) # this gives value of individual attributes
输出：
value of level attribute (i.e. log level) is: 0这里的日志级别0表示NOTSET
