內容簡介

　　《Python3麵嚮對象編程（第2版 影印版 英文版）》講解瞭類、數據封裝、繼承、多態、抽象和異常，著重強調瞭在一款設計良好的軟件開發過程中使用每個原則的時機。除瞭學習如何利用高層次的設計模式來創建可維護的應用程序，你還可以瞭解到字符串和文件處理的復雜性以及Python區分二進製數據和文本數據的方法。另外，單元測試的樂趣以及並發編程的難題也是少不瞭的。
　　書中更新瞭大量的內容，以反映齣近來核心Python庫的變化，這些新的特性在《Python3麵嚮對象編程（第2版 影印版 英文版）》備受贊譽的第1版麵世時還無法使用。除此之外，全書的結構也進行瞭重新調整和組織，提升瞭知識量，增強瞭閱讀體驗。
　　目標讀者如果你是初次接觸麵嚮對象編程技術，或是隻具備基本的Python技能，希望能夠深入學習如何正確地使用Python麵嚮對象編程技術來設計軟件，那麼《Python3麵嚮對象編程（第2版 影印版 英文版）》就是為你準備的。
　　你將從《Python3麵嚮對象編程（第2版 影印版 英文版）》中學到什麼通過創建類和定義方法來實現Python對象。
　　將相關的對象劃分成不同的類，通過類接口來描述這些對象的屬性和行為。
　　使用繼承來擴展類的功能。
　　明白什麼時候使用麵嚮對象特性，什麼時候不使用（後者更重要）。
　　瞭解什麼是設計模式，為什麼在Python中有這些不同的設計模式。
　　揭示單元測試的簡潔性及其在Python中的重要性。
　　理解Python3中常見的並發編程技術和陷阱。
　　探究用於開發大規模並發網絡係統的新模塊Async10。
