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 ')
By default, logging prints the log to the screen with a log level of WARNING and a log-level size relationship: CRITICAL > ERROR > WARNING > INFO > DEBUG > NOTSET, Of course, you can define the log level yourself.2. Configure the output format and mo

For Python, there are two problems that have plagued me these days:
There is no way to get the current line number and function name directly in 1.python. This is a question raised in the forum, and the bottom group is just guessing why Python does not offer __line__ and __func__ like __file__, but it does not find a solution at the end.
2. If a function does not know its name, how can it recursively invoke itself. This is a colleague of mine asked me, in fact, also get the function name, but it
When configuring the logging of the package, the gray "√" in front of the Containers,execute SQL task on the left indicates that the Execute SQL task inherits the configuration of the log records of the test log package.

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() and error() critical()5个级别, below
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 ()])

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.

What is logging? A log is a tracking event that occurs when the software is running, and the software developer can quickly locate the problem through the log. The event is also of importance, that is, the severity of the incident.When do I use the log?
