python的logging模块(logging是线程安全的)给应用程序提供了标准的日志信息输出接口。logging不仅支持把日志输出到文件,还支持把日志输出到TCP/UDP服务器,EMAIL服务器,HTTP服务器,UNIX的syslog系统等。在logging中主要有四个概念:logger、handler、filter和formatter,下面会分别介绍。logger Logger对象扮演了三重角色: 它给...
self.msg=msg##The following statement allows passing of a dictionary as a sole#argument, so that you can do something like#logging.debug("a %(a)d b %(b)s", {'a':1, 'b':2})#Suggested by Stefan Behnel.#Note that without the test for args[0], we get a problem because#during...
Moreover, logging in Python is straightforward and quick. You don’t need to install anything to get started with Python logging because the Python standard library includes a logging module. Simply import the logging module to use the module in your script. Printing vs. Logging Python developers...

The benefits of logging Basic logging Advanced configuration to logging An example of the use of loggingBenefits of LoggingYou may ask: “Why not just use printing?”When you run an algorithm and want to confirm it is doing what you expected, it is natural to add some print() statements ...
logging模块 re正则表达式 模块,使用代码实现了某个功能的代码集合。 类似于函数式编程和面向过程编程,函数式编程则完成一个功能,其他代码用来调用即可,提供了代码的重用性和代码间的耦合。而对于一个复杂的功能来,可能需要多个函数才能完成(函数又可以在不同的.py文件中),n个 .py 文件组成的代码集合就称为模块。

With Python’s native syslog support, you can add system logging to your scripts with just a few lines of code, replace printing to the console, and redirecting to files with powerful tooling that works with syslog, rsyslog, syslog-ng, and of course, SolarWinds® Loggly®. Let’s get...
