《經典原版書庫：python語言程序設計（英文版）》保持了liang博士系列叢書中一貫的、標志性的教與學的哲學：以實例教，由實踐學。書中采用了他所提出的已經經過實踐檢驗的“基礎先行”的方法，即在定義類之前，首先使用清晰簡明的語言介紹基本程序設計概念，如選擇語句、循環和函數；在介紹面向對象程序設計和gui編程之前，首先介紹基本邏輯和程序設計概念。書中除了給出一些以游戲和數學為主的典型實例外，還在每章的開始使用簡單的圖形給出一兩個例子，以激發學生的學習興趣。
本書特色：
以“基礎先行”方法介紹基本程序設計概念和方法，幫助學生循序漸進地學習所有必需和重要的基本概念。
以“問題驅動”方法講授程序設計技術，強調問題求解，而非語法。通過廣泛的趣味性實例（涉及數學、自然科學、商業、金融、游戲、動畫和多媒體領域）來激發學生的學習興趣，為求解這些問題，適時地引入相關的語法和庫。
可以靈活介紹gui相關主題。第1～6章使用內置的turtle圖形模塊，其余部分使用tkinter，這兩種工具都是簡單、易學的程序設計教學工具。每章的開始都有gui實例，每章末尾還有專門的gui練習。
