Introduction to Java Programming, Ninth Edition

Introduction to Python Programming and Data Structures Second Edition

Introduction to Python Programming and Data Structures Second Edition by Y. Daniel Liang is an interactive ebook, called Revel for Liang Python, which is the second edition improved upon the first edition. The Revel book has the built-in interactives for CodeAnimation, LiveExample, and AlgorithmAnimation. These interactives are very helpful for new students to learn programming. Instructors can assign auto-graded small exercises and projects.

Key New Features:

The title is changed to Introduction to Python Programming and Data Structures with new enhancements on data structures. The book first introduces using data structures and then implementing data structures. The book covers all topics in a typical data structures course.
The selection statements are moved from Chapter 4 (in 1E) to Chapter 3 (in 2E) to give students opportunity to learn this simple programming constructs to write interesting code early.
The lists are moved from Chapter 10 (in 1E) to Chapter 7 (in 2E) to enable students to write the code to store and process a collection of data early.
Chapter 9 in 1E are split into two chapters 10 and 11 in this edition to give more in-depth coverage on Python GUI programming using Tkinter.
Chapters 16–23 are brand new chapters for introducing data structures using Python. New appendixes on regular expressions, command-line arguments, and bitwise operations are added to this edition.
Many chapters in early part of the book have a section on common errors and pitfalls to steer students away from common programming errors.
The int and float functions are used to convert a string into an integer or a float value, rather than using the eval function. Using the int and float functions makes the code more intuitive, robust, and secure. (This change triggers rewriting many programs and exercises in the book.)
This edition provides many new examples and exercises to motivate and stimulate student interest in programming. (This is the hallmark for every new edition of the Liang book.)
Provided additional exercises not printed in the book. These exercises are available for instructors only.

The following table shows the correlation of the changes to the previous edition.

Chapter 1 Introduction to Computers, Programs, and Python	The introduction to computers and programming languages has been updated. Move the section on syntax errors, runtime errors, and logic errors from Chapter 2 to Chapter 1 to introduce programming errors early on. Move programming style and doc here from Chapter 2 to Chapter 1 to foster good programming style early.	Chapter 1
Chapter 2 Elementary Programming	New introductory problem to motivate students. Add software development process section to introduce analysis and design as well coding. Expand the coverage on debugging. Add a new section on Common Errors and Pitfalls Move the section on syntax errors, runtime errors, and logic errors to Chapter 1 to introduce programming errors early on. Move the section on syntax errors, runtime errors, and logic errors to Chapter 1 to introduce programming errors early on. The int and float functions are used to convert a string into an integer or a float value, rather than using the eval function. Using the int and float functions makes the code more intuitive, robust, and secure.	Chapter 2
Chapter 3 Selections	New figure to show multiple-alternative if statements Add a new section on Common Errors and Pitfalls Add debugging in this chapter. Move examples and exercises using characters and strings such as the GuessBirthday case study to Chapter 4.
