Master the Powerful Python 3 Standard Library through Real Code Examples

“The genius of Doug’s approach is that with 15 minutes per week, any motivated programmer can learn the Python Standard Library. Doug’s guided tour will help you flip the switch to fully power-up Python’s batteries.”

–Raymond Hettinger, Distinguished Python Core Developer

The Python 3 Standard Library contains hundreds of modules for interacting with the operating system, interpreter, and Internet–all extensively tested and ready to jump-start application development. Now, Python expert Doug Hellmann introduces every major area of the Python 3.x library through concise source code and output examples. Hellmann’s examples fully demonstrate each feature and are designed for easy learning and reuse.

You’ll find practical code for working with text, data structures, algorithms, dates/times, math, the file system, persistence, data exchange, compression, archiving, crypto, processes/threads, networking, Internet capabilities, email, developer and language tools, the runtime, packages, and more. Each section fully covers one module, with links to additional resources, making this book an ideal tutorial and reference.

The Python 3 Standard Library by Example introduces Python 3.x’s new libraries, significant functionality changes, and new layout and naming conventions. Hellmann also provides expert porting guidance for moving code from 2.x Python standard library modules to their Python 3.x equivalents.

• Manipulate text with string, textwrap, re (regular expressions), and difflib
• Use data structures: enum, collections, array, heapq, queue, struct, copy, and more
• Implement algorithms elegantly and concisely with functools, itertools, and contextlib
• Handle dates/times and advanced mathematical tasks
• Archive and data compression
• Understand data exchange and persistence, including json, dbm, and sqlite
• Sign and verify messages cryptographically
• Manage concurrent operations with processes and threads
• Test, debug, compile, profile, language, import, and package tools
• Control interaction at runtime with interpreters or the environment

通过真实代码示例掌握功能强大的Python3标准库

“Doug方法的天才之处在于，只要每周花15分钟，任何有动力的程序员都可以学习Python标准库。Doug的导游将帮助您拨动开关，为Python的电池完全通电。

-著名的Python核心开发人员Raymond Hettinger

Python3标准库包含数百个用于与操作系统、解释器和Internet交互的模块-所有这些模块都经过了广泛的测试，可以启动应用程序开发。现在，Python专家Doug Hellmann通过简洁的源代码和输出示例介绍了Python3.x库的各个主要方面。Hellmann的示例充分展示了每个功能，并且设计为易于学习和重复使用。

您将发现用于处理文本、数据结构、算法、日期/时间、数学、文件系统、持久性、数据交换、压缩、归档、加密、进程/线程、网络、Internet功能、电子邮件、开发人员和语言工具、运行时、包等的实用代码。每一节都完全涵盖了一个模块，并提供了指向其他资源的链接，使本书成为理想的教程和参考资料。

Python3标准库的范例 介绍了Python3.x的新库、重要的功能更改以及新的布局和命名约定。Hellmann还为将代码从2.x版本的Python标准库模块迁移到与之对应的3.x版本的版本提供了专家移植指导。

• 使用字符串、textwrap、re(正则表达式)和Difflib操作文本
• 使用数据结构：枚举、集合、数组、heapq、队列、结构、复制等
• 使用FuncTool、iterTools和Conextlib优雅而简洁地实现算法
• Handle dates/times and advanced mathematical tasks
• 归档和数据压缩
• 了解数据交换和持久性，包括JSON、DBM和SQLite
• 对消息进行加密签名和验证
• Manage concurrent operations with processes and threads
• 测试、调试、编译、分析、语言、导入和打包工具
• 在运行时控制与解释器或环境的交互
