Python Cookbook, 3rd Edition (Chinese Edition)

Python Cookbook, 3rd Edition (Chinese Edition) is the Python volume in O'Reilly's classic Cookbook series. The original third edition was written by David Beazley and Brian K. Jones, and the Chinese edition was translated by Chen Ge and published by Posts & Telecom Press in 2015. The book is organized around a "Problem, Solution, Discussion" structure, with 15 chapters and more than a hundred topics, and all example code was written and tested under Python 3.3. It covers data structures and algorithms, strings and text, numbers, dates and times, iterators and generators, files and I/O, data encoding and processing, functions, classes and objects, metaprogramming, modules and packages, network and web programming, concurrency, useful scripts and system administration, testing, debugging and exceptions, and C extensions. Each section first states the problem to be solved, then gives code that can be used directly, and finally explains why the code works and what its limitations and alternatives are. Unlike introductory tutorials, this book does not teach the basics of Python syntax; it focuses instead on idiomatic modern Python: context managers, decorators, generators, descriptors, metaclasses, asyncio and other concurrency approaches, and lesser-known modules in the standard library. In the preface, the authors explain that they favored topics that demonstrate general programming techniques (that is, programming patterns) rather than only very narrow, specific problems, and that they deliberately included many features new in Python 3 relative to Python 2 that even experienced programmers may not know well. Readers can read it chapter by chapter or look up the chapter matching their specific problem.
