python logging debug

Implemented a simple version of the Logging.config, support the general configuration through the config file. There is a better way to feel, and it is to use the Logging.config.fileConfig (Log_config_file) method to read it and modify it by modifying the handler mode. The code is as follows: """Project Trace System"""Import SysImport ConfigparserImport loggingImport Logging.configImport warnings if __name__ = = "__main__":Log_config_file = "Log.conf"Log_data_file = "Logs/run.log" Level_dic =

1. Simply print the log to the screenImport logginglogging.debug ('This isdebug message') logging.info (' This is info message ' ) logging.warning ('This iswarning message') on-screen printing : IS warning messageBy default, logging prints the log to the screen with a log level of warning;Log level size relationships are: CRITICAL > error> WARNING > INFO > DEBUG > NOTSET, and of course you can define the

less convenient, can be configured to use logging:Import logginglogging.basicconfig (FileName='/users/wenli.xu/desktop/log1.log', Level=logging.info)where filename indicates the log path, level indicates that only the severity is greater than or equal to info to be logged (the logging default is warning).The severity is lighter to heavy: debug,info,warning,error,criticalThe following methods can then be us

Describe:Many programs have logging requirements, and the information contained in the log is a normal program access log, there may be errors, warnings and other information output, Python's logging module provides a standard log interface, you can use it to store various formats of the log.The logging log can be divided into 5 levels:

I. Introduction and use of logging modulePython uses the logging module to log logs involving four main classes, each of which uses the following functions: Logger: Provides an interface that the application can use directly Handler: Send (logger created) log records to the output of the appropriate destination SetLevel: Provides a fine-grained device to determine which level of
