Python Programming: An Introduction to Computer Science, 3rd Ed.

This third edition of John Zelle's Python Programming continues the tradition of updating the text to reflect new technologies while maintaining a time-tested approach to teaching introductory computer science. An important change to this edition is the removal of most uses of eval and the addition of a discussion of its dangers. In our increasingly connected world, it's never too early to begin considering computer security issues. This edition also uses several new graphics examples, developed throughout chapters 4-12.

約翰·澤爾（John Zelle）的《Python程式設計》第三版延續了更新內容以反映新技術的傳統，同時保持了教授入門級計算機科學的經過時間考驗的方法。本版的一個重要改變是大部分eval的使用被移除，並增加了對其危險性的討論。在我們日益連接的世界中，開始考慮計算機安全問題永遠不會太早。本版還使用了幾個新的圖形示例，這些示例分佈在第4章至第12章。
