The Practice of Computing Using Python introduces CS1 students (majors and non-majors) to computational thinking using Python. With data-manipulation as a theme, readers quickly see the value in what they’re learning and leave the course with a set of immediately useful computational skills that can be applied to problems they encounter in future pursuits. The book takes an “object-use-first” approach—writing classes is covered only after students have mastered using objects.

BOOK FEATURES:

Data Manipulation

Data manipulation is a theme. The examples range from text analysis to breast cancer classification. Along the way, we provide some analysis examples using simple graphing. To incorporate drawing and graphing, we use established packages instead of developing our own: one is built in (Turtle Graphics); the other is widely used (matplotlib with NumPy).

We have tried to focus on non-numeric examples in the book, but some numeric examples are classics for a good reason. For example, we use a rational-numbers example for creating classes that overload operators. Our goal is always to use the best examples.

Problem Solving and Case Studies

Throughout the text, we emphasize problem solving, especially a divide-and-conquer approach to developing a solution. Three chapters (3, 10, and 13) are devoted almost exclusively to program development. Here we walk students through the solution of larger examples. In addition to design, we show mistakes and how to recover from them. That is, we don’t simply show a solution but show a process of developing a solution.

Code Examples

There are over 180 code examples in the text—many are brief, but others illustrate piecemeal development of larger problems.

Interactive Sessions

The Python interpreter provides a wonderful mechanism for briefly illustrating programming and problem-solving concepts. We provide almost 250 interactive sessions for illustration.

Exercises and Programming Projects

Practice, practice, and more practice. We provide over 275 short exercises for students and nearly 30 longer programming projects (many with multiple parts).

Self-Test Exercises

Embedded within the chapters are 24 self-check exercises, each with five or more associated questions.

Programming Tips

We provide over 40 special notes to students on useful tips and things to watch out for. These tips are boxed for emphasis.
