《Professional Python》是一本深入讲解高级Python编程技巧的专业书籍,适合初学者和中级程序员阅读。它不仅涵盖了基础知识,还探讨了诸如装饰器、上下文管理器、魔术方法、类工厂、元类、正则表达式等不那么常见的工具和构造,旨在帮助读者编写更简洁、可维护的代码,提升应用的健壮性和效率。本书采用“Python 3优先”的教学策略,兼顾多个版本,确保内容的长期适用性。 书中内容结构丰富,分为五个部分: 1. **函数与控制流**: - 第一章介绍了装饰器(Decorators),它们允许在不修改原有函数代码的情况下,增强其功能或行为。 - 第二章讨论了上下文管理器(Context Managers),用于资源管理和异常处理,确保在操作完成后正确释放资源。 2. **面向对象编程**: - 第四章讲解魔术方法(Magic Methods),如`__init__`、`__str__`等,这些特殊方法是实现对象动态特性的关键。 - 第五章探讨元类(Metaclasses),它们控制类的创建过程,可以用来实现自定义类的行为。 - 第六章介绍类工厂(Class Factories),提供灵活的方式来创建具有相似属性和行为的类实例。 - 第七章涉及抽象基类(Abstract Base Classes),用于定义接口和模板。 3. **数据处理**: - 第八章讲述了字符串和Unicode的处理,包括编码和解码、格式化等。 - 第九章深入讲解正则表达式(Regular Expressions),用于文本搜索和模式匹配。 4. **进阶主题**: - 第十章比较Python 2与Python 3之间的差异,帮助开发者在不同版本间迁移。 - 第十一章介绍单元测试(Unit Testing),强调了测试对于代码质量和可靠性的重要性。 - 第十二章介绍了命令行工具(CLI Tools)的使用,提升开发效率。 - 第十三章讲解异步编程(asyncio),适应现代并发需求。 5. **风格与最佳实践**: - 第十四章关注编程风格和最佳实践,以确保代码的清晰度和一致性。 《Professional Python》通过每个主题的理论讲解、应用场景讨论和实战教程,让读者能够理解和掌握这些高级技术,并在实际项目中运用。无论是初次接触Python的开发者还是寻求进一步提升的专家,这本书都是提高编程技能和创建高质量应用程序的重要资源。

Paperback: 288 pages Publisher: Wrox; 1 edition (October 19, 2015) Language: English ISBN-10: 1119070856 ISBN-13: 978-1119070856 Master the secret tools every Python programmer needs to know Professional Python goes beyond the basics to teach beginner- and intermediate-level Python programmers the little-known tools and constructs that build concise, maintainable code. Design better architecture and write easy-to-understand code using highly adoptable techniques that result in more robust and efficient applications. Coverage includes Decorators, Context Managers, Magic Methods, Class Factories, Metaclasses, Regular Expressions, and more, including advanced methods for unit testing using asyncio and CLI tools. Each topic includes an explanation of the concept and a discussion on applications, followed by hands-on tutorials based on real-world scenarios. All sample code is available for download from the companion website, and the "Python 3 first" approach covers multiple current versions, while ensuring long-term relevance. Python offers many tools and techniques for writing better code, but often confusing documentation leaves many programmers in the dark about how to use them. This book shines a light on these incredibly useful methods, giving you clear guidance toward building stronger applications. Learn advanced Python functions, classes, and libraries Utilize better development and testing tools Understand the "what," "when," "why," and "how" Download example code to start programming right away More than just theory or a recipe-style walk-through, this guide helps you learn — and understand — these little-known tools and techniques. You'll streamline your workflow while improving the quality of your output, producing more robust applications with cleaner code and stronger architecture. If you're ready to take your Python skills to the next level, Professional Python is the invaluable guide that will get you there.
