Python的簡潔讓你可以快速達到高產水平，但是
這通常意味著你並沒有用到它提供的所有功能特性。
有了盧西亞諾·拉馬略著的《流利的Python語言（影
印版）（英文版）》這本容易上手的指南，你將學會
如何利用那些十分優秀但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
帶領你們遍歷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扭曲成適合
他們從其他語言中學到的模式，而從未發現超出他們
經驗的Python特性。通過這本書，那些Python程序員
將完全學會如何高效率地使用Python 3。
