说明：  本书包括python程序设计的方方面面，首先从python的安装开始，随后介绍了python的基础知识和基本概念，包括列表、元组、字符串、字典以及各种语句。然后循序渐进地介绍了一些相对高级的主题，包括抽象、异常、魔法方法、属性、迭代器。此后探讨了如何将python与数据库、网络、c语言等工具结合使用，从而发挥出python的强大功能，同时介绍了python程序测试、打包、发布等知识。最后，作者结合前面讲述的内容，按照实际项目开发的步骤向读者介绍了几个具有实际意义的python项目的开发过程。
(This book covers all aspects of python programming. It starts with the installation of python, and then introduces the basic knowledge and basic concepts of python, including lists, tuples, strings, dictionaries and various sentences. Then introduced some relatively advanced topics step by step, including abstraction, exceptions, magic methods, attributes, and iterators. After that, I discussed how to use python with tools such as database, network, c language, etc., so as to give play to the powerful functions of python. At the same time, I introduced the knowledge of python program testing, packaging and publishing. Finally, the author combined the content described above and introduced the development process of several python projects with practical significance to the readers according to the actual project development steps.)
