Python Programming

This book is a Python textbook written for a programming language course aimed at undergraduate majors at colleges and universities. Using Python 3.6.5 as the language environment, it systematically explains how Python works, programming techniques, implementation methods, and practical applications. The book has 10 chapters, covering in order environment and operations, data and expressions, input and output, control and structure, modules and functions, objects and methods, libraries, tables, and management, users and interfaces, graphics and images, and cases and deployment, forming a complete chain from language fundamentals to comprehensive application. The database portion uses SQL Server 2016, MySQL, and other DBMSs to explain database design and implementation methods, and provides complete runnable programs, so that after mastering the syntax readers can complete practical projects with data persistence. The textbook emphasizes linking theory with practice: each chapter includes examples and exercises, and key chapters such as data, expressions, and control structures include hands-on lab sessions to guide readers to verify and consolidate what they have learned. The author's exposition is accessible and rigorously structured, with a practical orientation, making it suitable for both classroom teaching and student self-study. This book can serve as a programming language textbook for undergraduate majors such as computer science and technology, data science and big data technology, information security, software engineering, network engineering, information management and information systems, e-commerce, logistics, and finance and economics, and can also be a reference book for technical personnel engaged in programming and application development.
