Many of the modules in Python are very bull X, previously mentioned in the logging module (which is similar to the Java log4j), since a recent script involving network troubleshooting requires log output, which is used in Python's logging module to implement. When the logs are all written to a file, the files become more and more over time, and you can use the Timedrotatingfilehandler method or the Rotating
Many programmers have the need to log, and the log contains information that has normal program access logs, there may be errors, warnings and other information output, Python logging module provides a standard log interface, you can store a variety of logs through it, you can store various forms of log , the logging log can be divided into five levels: Debug (), info (), warning (), error (), and Critical

Introduction Command Line Parameter Parsing and Application
Program Configuration and logging, as the skeleton of an application, can be seen everywhere. Therefore, the Apache Software organization has developed a set of common class libraries to help software developers build these "skeleton. Where:
#8226; commons CLI for command line Parsing
#8226; commons configuration is used to read configuration information in properties or XML format
#8226;
Logging allows us to debug and track the behavior and status of an application at any time. Logging is an indispensable part of any large-scale application. Therefore, there are already many third-party logging tools that allow developers to write their own logging APIs. In fact, even JDK has a constructed
Introduction to the python logging Module
Use python to write programs, and sometimes use the log system. Especially for dynamic languages like python, many errors can only be found during running. A good log system is very important to Python programs.
The simplest solution is to directly use print to output the running information. However, this is too simple and there is no grading function. If you want to remove the running information for debuggi
Python's logging module provides a common logging system that can be easily used by third-party modules or applications. This module provides different log levels and can record logs in different ways, such as files, HTTP get/post,smtp,socket, etc., and can even implement specific logging methods on their own.The logging

Writing logs in the Code is a basic and basic skill apart from implementing functions using the code. It is a required skill. But so far, there are not m
In many applications, a log module is used to record key information about the system's operation, so that it can track the health of the system. In the. NET platform, there are well-known third-party open-source log components log4net,c++, with familiar log4cpp, and in Python we don't need a third-party log component because it has provided us with an easy-to-use and powerful logging module: logging. The

Logging is an essential feature in almost all programs. Logging can help us Debug Programs, run time-consuming programs in the background program or Logging can help us to record whether the program runs correctly and whether exceptions are thrown.
