在我们这个技术驱动的社会中,小工具和硬件只是硬币更明显的一面。在这一章中,我们将讨论编程的基础知识。我们还将看看数字系统的可见部分:硬件。 到底什么是编程? 基本上,编程是告诉数字设备,比如你的个人电脑,做什么的行为。我们键入由编程语言定义的命令列表,以便发生有用或有趣的事件。正确编程的计算机运行着世界...
Obviously, there can be side effects when calling some variables, and it’d be either foolish or a security hole to allow the template system to access them. A good example is the delete() method on each Django model object. The template system shouldn’t be allowed to do something like...
For instance, when we perform text pattern matching in Python, we create pattern objects, and when we perform network scripting, we use socket objects. These other kinds of objects are generally created by importing and using modules and have behavior all their own. As we’ll see in later ...

” You can always comment out or remove the print statements later when you are confident your code is working properly. We’ve covered a lot of ground in this chapter. We’ve discussed how to import modules, basic data types and their functions and methods, pattern matching, print ...
There are different syslog format RFCs –RFC 3164is obsolete but still found in the wild as default configuration (matching the pattern above), whileRFC 5424is more modern, including datetime with timezone information. Parsing this format can be tricky, so let's ask Code Suggestions for advice...
