使用 logger 对象,我们可以分别为不同的模块或功能配置不同的日志记录器。 importlogging# 创建一个 logger 对象logger=logging.getLogger("exampleLogger")logger.setLevel(logging.INFO)# 创建文件处理器file_handler=logging.FileHandler('example.log')formatter=logging.Formatter(log_format)file_handler.setFormatter(...

logging.makeLogRecord(attrdict) 创建并返回一个新的 LogRecord 实例,实例属性由 attrdict 定义。 此函数适用于接受一个通过套接字传输的封存好的 LogRecord 属性字典,并在接收端将其重建为一个 LogRecord 实例。 logging.basicConfig(**kwargs) 通过使用默认的 Formatter 创建一个 StreamHandler 并将其加入根日志记...
