python logging levels

on the example above, we will discuss several of the most commonly used APIs: Logging. getLogger ([name]) Returns a logger instance. If no name is specified, the root logger is returned. As long as the names are the same, the returned logger instances are the same and only one, that is, the names and logger instances correspond one to one. This means that you do not need to pass the logger instance in each module. You only need to know the name to ge

write a format formater1, so you can Logger.addhandler (stream_handler) return Loggerlogger = MyLogger (' Logging.log ', File=false) logger.warning (' Cheerleader ') logger.debug (' Debug message ') The Ogging library provides multiple components: Logger, Handler, Filter, Formatter. The Logger object provides an interface that the application can use directly, handler sends logs to the appropriate destination, and filter provides a way to filter the log information formatter specify the log dis

display.Filter: Provides an elegant way to determine whether a log record is sent to handler.Formatter: Specifies the specific format of the logging output. The formatter method requires two parameters: the format string of the message and the date string, both of which are optional.Similar to log4j, calls to Logger,handler and log messages can have specific log levels (level), only at

Logging module:Many programs have logging requirements, and the information contained in the log includes both normal program Access logs and possibly errors, warnings, and other information output. Python's logging module provides a standard log interface through which you can store logs in a variety of formats. Logging's logs can be divided into debug (), info

The logging encapsulation of python is updated. Currently, it supports outputting data to the console, file, and socket at the same time. At the same time, you can clear all the handler of the root logger When configuring config_logging or config_logging_plus, avoid repeated output in some cases.DetailsCodeAs follows: # -*-Coding: UTF-8 -*- ''' Modified on 2012-11-27 @ Summary: Clear old root logger ha

The logging module is a built-in module of Python, the main feature of logging is that it can be shared between modules, and provides different log levels, each module sends logs to the same file or other place, and the most common scenario is to record the information in log files. 1.
