Python’s simplicity lets you become productive quickly, but often this means you aren’t using everything it has to offer. With the updated edition of this hands-on guide, you’ll learn how to write effective, modern Python 3 code by leveraging its best ideas.
Don’t waste time bending Python to fit patterns you learned in other languages. Discover and apply idiomatic Python 3 features beyond your past experience. Author Luciano Ramalho guides you through Python’s core language features and libraries and teaches you how to make your code shorter, faster, and more readable.
Featuring major updates throughout the book, Fluent Python, second edition, covers:
Special methods: The key to the consistent behavior of Python objects
Data structures: Sequences, dicts, sets, Unicode, and data classes
Functions as objects: First-class functions, related design patterns, and type hints in function declarations
Object-oriented idioms: Composition, inheritance, mixins, interfaces, operator overloading, static typing and protocols
Control flow: Context managers, generators, coroutines, async/await, and thread/process pools
Metaprogramming: Properties, attribute descriptors, class decorators, and new class metaprogramming hooks that are simpler than metaclasses

随着互联网的迅速发展，几乎所有工具软件和程序语言都支持的正则表达式也变得越来越强大和易于使用。本书是讲解正则表达式的经典之作。本书主要讲解了正则表达式的特性和流派、匹配原理、优化原则、实用诀窍以及调校措施，并详细介绍了正则表达式在Perl、Java、.NET、PHP中的用法。
本书自第1 版开始着力于教会读者“以正则表达式来思考”，来让读者真正“精通”正则表达式。该版对PHP的相关内容、Java1.5和Java1.6的新特性作了可观的扩充讲解。任何有机会使用正则表达式的读者都会从中获益匪浅。
