1. Simply print the log to the screen
Import loggingLogging.debug (' This is Debug message ')Logging.info (' This is Info message ')Logging.warning (' This is warning message ')On-screen printing:WARNING:root:This is WARNING message
By 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 log level yourself.

IntroductionThe Apache Web server can be configured to give the server administrator important information about what it is functioning And what issues, if any, need to be addressed.The main avenue for providing feedback to the administrator are through the use of the log files. Apache have a very configurable logging mechanism that can is used to output messages to different places based on instruct Ions.In the This guide, we'll look at what to utili

When you are developing a program, debugging (debugging) and logging are very important tasks. However, there are too many logging APIs available because they are both good, it is difficult to make a choice. the foreign Java Forum also has some discussions on these logging methods.

As we all know during the development process, logs record the key parts of debugging. Especially when a product is released, when a user feedback has some crashes or other problems, logs are particularly important, by analyzing logs, you can quickly find out the crux of the problem and quickly solve the problem.
Properly recording user logs is an art. What kind of information should be written into the log (usual
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 Python, we don't need a third-party log component because it has provided us with an easy-to-use and powerful log module: logging.
Python prints all property values for an object:
def prn_obj (obj): print ' \ n '. Join (['%s:%s '% item for item in Obj.__dict__.items ()])

Many programs have logging requirements, and the log contains information that has normal program access logs, there may be errors, warnings and other information output, Python's logging module provides a standard log interface, you can store various formats of the log, logging log can be divided into Debug, info, warning, error, critical 5 levels, let's take a
The log API provided by JDK is officially released in jdk1.4. Java logging can be used for application, JSP/servlet, and EJB.
The API outputs debugging information and can also be used to record information related to security conflicts during the program running. All this effectively ensures the robustness and maintainability of the program.

Of course, there is a
