內容簡介

　　Python的簡潔讓你可以快速達到高産水平，但是這通常意味著你並沒有用到它提供的所有功能特性。
　　有瞭《流利的Python語言（影印版 英文版）》，你將學會如何利用那些很容易被忽視的特性來編寫有效且通順的Python代碼。作者Luciano Ramalho將帶領你們遍曆Python的核心語言特性和程序庫，並展示精簡代碼、優化速度和可讀性的方法。
　　很多富有經驗的程序員嘗試將Python扭麯成適閤他們從其他語言中學到的模式，而從未發現超齣他們經驗的Python特性。通過《流利的Python語言（影印版 英文版）》，那些Python程序員將完全學會如何高效率地使用Python 3。

精彩書摘

　　《流利的Python語言（影印版 英文版）》：
　　In concluding the chapter， we mentioned how several built—in types are registered to ABCs in the collections.abe module so you can ask isinstance（memoryview，abc.Sequence） and get True， even if memoryview does not inherit from abc.Se quence.And finally we went over the_subclasshook_magic， which lets an ABC recognize any unregistered class as a subclass， as long as it passes a test that can be as simple or as complex as you like—the examples in the standard library merely check for method names.
　　To sum up， I'd like to restate Alex Martelli's admonition that we should refrain from creating our own ABCs， except when we are building user—extensible frameworks—which most of the time we are not.On a daily basis， our contact with ABCs should be subclassing or registering classes with existing ABCs.Less often than subclassing or registering， we might use ABCs for isinstance checks.And even more rarely—ifever—we find occasion to write a new ABC from scratch.
