Summary

Published by Chemical Industry Press in 2022 and written by Mingri Keji, Python from Scratch is an introductory, hands-on Python tutorial for readers with no prior programming experience. The book runs to four parts and 21 chapters, about 576,000 Chinese characters, and comes with QR-code teaching videos and all program source files. The book proceeds in the order basics, advanced topics, applications, and projects. The basics part begins with setting up Python development environments on Windows, Linux, and macOS, then introduces variables and basic data types, input and output, operators and expressions, program control structures, and operations on common data containers such as sequences, lists, tuples, and strings, before moving on to dictionaries and sets and regular expressions. The advanced part covers functions, modules and packages, object orientation and classes, file I/O, exception handling, and program debugging, helping readers build a complete framework of the language. The applications part introduces turtle graphics and PyQt5 graphical interface design. The projects part closes with three small projects: navigating a maze with turtle graphics, developing a web crawler, and building an AI image recognition assistant, which tie together what has been learned. Code in the book is commented almost line by line, and short sidebars labeled Note, Explanation, and Tip are interspersed. Combined with a teaching rhythm of one concept, one example, one result, and one commentary, this lowers the barrier to self-study. The book suits Python beginners and self-learners in web crawling and artificial intelligence, and can also serve as a textbook or training reference for relevant university courses.

Editor's review

对零基础读者来说，学Python最难的不是语法，而是不知道从哪儿下手、装了环境跑不通、代码看不懂。这本书正是围绕这几点设计的。第一，脉络清晰。全书4篇21章，从装环境、变量、控制流，到函数、类、文件与异常，再到海龟绘图、PyQt5界面、爬虫和AI图像识别，一条主线走完，不东一榔头西一棒子，读者始终知道自己站在整个知识地图的哪一格。第二，讲练结合。书中的讲解按“一个知识点、一个例子、一个结果、一段评析”的方式展开，代码几乎逐行加了注释，新手照着敲也能看懂每一行在做什么，而不是只把书上代码抄一遍就算学过。第三，配套资源较实用。每章都配有扫码即看的视频讲解，另附程序源文件、资源库与题库，卡住时可以对照视频排查，自学时不容易因为一个小环境问题就放弃。当然，本书面向入门，深度有限：语言层面的原理、性能优化和工程化实践讲得不多，需要读者在入门后继续补充。作为第一本Python学习用书，它把门槛压得很低，把练习排得很密，这一点对新手尤其可贵。

Who it's for

A good fit for

完全没有编程基础、想系统入门Python的初学者
在校大学生，需要一本可按章节推进的Python课程参考书
想自学网络爬虫、图像识别，但语言基础薄弱的转行者
偏好边看视频边敲代码、需要配套素材辅助自学的读者

Not a good fit for

已有Python基础，想深入了解语言原理与底层实现的读者
希望系统学习数据分析、机器学习算法理论的读者
需要工程化、分布式部署等开发经验的中高级程序员

Reading tips

先照着第1章把开发环境装好并跑通第一个程序，后面的章节才不至于卡在环境问题上
每章至少亲手敲一遍示例代码，再做课后练习，不要只阅读不运行
学完第16章后可以开始尝试第19—21章的项目，边做边回头补前面的知识点
入门完成后换一本讲项目实践或数据分析的书继续进阶，避免停留在语法层面

FAQ

这本书适合完全没有编程经验的人吗？

适合。本书是为零基础读者编写的，从安装Python、认识变量和数据类型讲起，对代码逐行注释，还配有扫码视频，没有编程经验也能跟上节奏。不过前期环境搭建仍建议按书中步骤一步步操作。

这本书配有视频和源代码吗？

根据出版社与电商平台介绍，书中各章节配有扫码可观看的教学视频，并提供全部程序源文件和附赠资源库、题库等，方便读者边看边练、遇到问题对照排查。

这本书讲的是Python 2还是Python 3？

书中按Python 3进行编写（介绍变量、字符串、类、文件I/O以及PyQt5等现代用法），具体版本细节以书中第1章“Python的版本”一节的说明为准。

同名书有好几种，怎么确认买的是这一本？

请核对作者为“明日科技”、出版社为“化学工业出版社”、出版年为2022年、ISBN为9787122404510、约360页。市面上还有约翰·保罗·穆勒的第2版（人民邮电出版社）等同名书，注意区分。

看完这本书能直接找工作吗？

本书定位是入门，覆盖语法基础、常用库入门和三个小项目，能帮你建立完整的知识框架和动手能力，但不足以直接胜任开发岗位。建议在此基础上继续学习工程实践、数据库与一个完整项目后再考虑求职。
