Effective Python: 2nd Edition pdf epub mobi txt 电子书 下载 2024
Updated and Expanded for Python 3
It’s easy to start developing programs with Python, which is why the language is so popular. However, Python’s unique strengths, charms, and expressiveness can be hard to grasp, and there are hidden pitfalls that can easily trip you up.
This second edition of Effective Python will help you master a truly “Pythonic” approach to programming, harnessing Python’s full power to write exceptionally robust and well-performing code. Using the concise, scenario-driven style pioneered in Scott Meyers’ best-selling Effective C++, Brett Slatkin brings together 90 Python best practices, tips, and shortcuts, and explains them with realistic code examples so that you can embrace Python with confidence.
Drawing on years of experience building Python infrastructure at Google, Slatkin uncovers little-known quirks and idioms that powerfully impact code behavior and performance. You’ll understand the best way to accomplish key tasks so you can write code that’s easier to understand, maintain, and improve. In addition to even more advice, this new edition substantially revises all items from the first edition to reflect how best practices have evolved.
Key features include
30 new actionable guidelines for all major areas of Python
Detailed explanations and examples of statements, expressions, and built-in types
Best practices for writing functions that clarify intention, promote reuse, and avoid bugs
Better techniques and idioms for using comprehensions and generator functions
Coverage of how to accurately express behaviors with classes and interfaces
Guidance on how to avoid pitfalls with metaclasses and dynamic attributes
More efficient and clear approaches to concurrency and parallelism
Solutions for optimizing and hardening to maximize performance and quality
Techniques and built-in modules that aid in debugging and testing
Tools and best practices for collaborative development
Effective Python will prepare growing programmers to make a big impact using Python.
Brett Slatkin is a principal software engineer at Google. He is the technical co-founder of Google Surveys, the co-creator of the PubSubHubbub protocol, and he launched Google’s first cloud computing product (App Engine). Fourteen years ago, he cut his teeth using Python to manage Google’s enormous fleet of servers. Outside of his day job, he likes to play piano and surf (both poorly). He also enjoys writing about programming-related topics on his personal website (https://onebigfluke.com). He earned his B.S. in computer engineering from Columbia University in the City of New York. He lives in San Francisco.
增加了一些python3.8的新特性比如walrus operator,第六章metaclass略难
评分这本书除了第六章的metaclass以外对于新手还是比较友好的,每节末尾的小总结很不错,可以快速回顾小节内容。 另外,作者在讲某个概念的时候,往往会从问题开始,先给出初步的解决方案,然后再慢慢改进,最后提出关键的概念,比较循序渐进。 几个之前不知道的技巧:enumerate,F-string,generator & itertool,decoration,classmethod,decorator & metaclass,ThreadPoolExecutor,try/except/else/finally, Cython,unittest. 不足的是作者没有去和其他语言比较,或者去讨论Python核心的一些东西,比如everything is an object等等。
评分新版抛弃了Python 2,介绍了一些Python 3的新特性(Python 3.8);这本书比较好的地方是,每个知识点举例比较详细,并且通过对比告诉你为什么要这么做。
评分如果要我选一本python开发者必看的书,那么不是fluent python,也不是python cookbook,而必须是这本effective python。简直太实用了!

评分Effective Python 59 SPECIFIC WAYS TO WRITE BETTER PYTHON 这本书终于读完了。从这本书里学到不少经验,以及之前忽略的知识。书中部分内容也是库的内容(这么说有失公允,大部分属都会有抄库文档的嫌疑的,因为文档包含了最多的信息),也有很多内容基本上是常识,比如七八章...
