Logging in Python works by configuring loggers and setting log levels. Using a logging library provides structured logging and control over log output. You should prefer logging over print() because it decreases the maintainance burden and allows you to manage log levels.You...

3. Logging 导入 Logging模块是Python的内置模块,所以我们无需再显示进行安装。如果我们想要使用该模块,可以直接使用以下语句: importlogging 其中,Logging模块有很多内容,但是今天主要分享一个基础例子和一个高级例子供大家学习。 4. Logging Levels 日志记录级别(Logging Levels)允许我们设置更加具体的输出日志等级,例如调...
in, the corresponding string representation is returned. Otherwise, the string "Level %s" % level is returned. """defaddLevelName(level, levelName):""" Associate 'levelName' with 'level'. This is used when converting levels to text during message formatting. ...

A logger is configured to have alog level. This log level describes the severity of the messages that the logger will handle. Python defines the following log levels: DEBUG: Low level system information for debugging purposes INFO: General system information ...
To cater for this natural nesting, channel names are organized into a namespace hierarchy where levels are separated by periods, much like the Java or Python package namespace. So in the instance given above, channel names might be "input" for the upper level, and "input.csv", "input.xls...
