Python 不仅是一种编程语言，更是连接人工智能、科学计算和跨学科学习与研究的重要工具。掌握Python 语言程序设计，能够更高效地探索数据、构建智能系统，助力在不同领域中的创新。本书面向高校学生，按照《教育强国建设规划纲要（2024—2035 年）》中提出的打造培根铸魂、启智增慧的高质量教材要求，以应用性和实践性为主，采用零基础入门、循序渐进的方式进行编写，适合作为高校各类专业进行Python 程序设计教学的教材或参考书。
Python 语言由荷兰计算机科学家Guido van Rossum 在借鉴了C、C++、Unix shell 等著名编程语言优点的基础上开发创建，具有“优雅”“明确”“简单”的设计哲学特征，自1991 年第一个版本发布以来，历经多次版本迭代。凭借易于学习、拥有大量的支持库、可高效地开发各种应用程序等优势，Python 已被广泛应用于计算机程序设计教学、Web 开发、系统管理任务、科学计算、人工智能等领域。据TIOBE 指数统计，自2004 年以来，Python的使用量持续快速增长。得益于人工智能的迅猛发展，至2018 年，Python 已成为全球最受欢迎的编程语言之一。
本书编写组由从事近十年Python 语言程序教学的高校教师和企业一线的工程师组成，将教学经验、理论知识与应用实践相结合，经过多轮教学实践，终于完成了这本具有案例驱动、任务导向、工程化实训等特色的Python 语言程序设计教程。本书中的每个案例都经过编者的精心构思与设计，循序渐进地整合了不同层级和类别的知识点。编写过程中，编者坚持理论与实践相结合，采用工程化的方法将案例细分为不同的任务，激发读者的阅读积极性和完成某项任务的成就感。通过案例实践，读者不仅可以学到理论知识，掌握相关技术，还能在潜移默化中建立软件项目开发的整体意识，充分体现“做中学、学中做”的理念。本书知识结构层次分明，图文并茂，语言生动，通俗易懂。
本书共分7 章：第1 章概述，第2 章Python 语法基础，第3 章Python 基本应用，第4章函数，第5 章类与对象，第6 章基于tkinter 的桌面应用程序开发，第7 章基于Django的Web 应用程序开发。通过本书的学习，读者可以从一个编程“小白”开始快速掌握Python程序设计核心知识与技能，具备独立开发简单的桌面和Web 应用程序的能力，为后续将Python 应用于专业领域、解决专业问题、促进专业发展打下坚实基础。例如，数据工程专业的读者，借助本书所学，就能使用Python 编写数据分析程序；语言类专业的读者，基于本书的学习，能够开发自然语言处理与分析的相关程序。
本书由韩朝阳任主编，李彦会、韩曦航参与编写。本书初稿由韩朝阳完成，李彦会、韩曦航参与了后期的修订工作并对各章节习题进行撰写。陈瑛教授任主审。本书在编写过程中得到了上海杉达学院信息科学与技术学院领导和老师们的大力支持和帮助，本书的顺利出版与上海杉达学院教材建设项目资助、北京大学出版社的支持以及编辑的辛勤工作都密不可分，在此一并表示衷心的感谢！由于本书涉及内容广泛，编者水平有限，书中不妥和疏漏之处在所难免，欢迎广大读者批评指正。
