This textbook is an introduction to programming, computer application development, and the science of computing. It is meant to be used in a college-level introductory programming course. More than just an introduction to programming, the book is a broad introduction to computer science and to the concepts and tools used for modern computer application development. The computer programming language used in the book is Python, a language that has a gentler learning curve than most. Python comes with powerful software libraries that make complex tasks—such as developing a graphics application or finding all the links in a web page—a breeze. In this textbook, we leverage the ease of learning Python and the ease of using its libraries to do more computer science and to add a focus on modern application development. The result is a textbook that is a broad introduction to the field of computing and modern application development. The textbook’s pedagogical approach is to introduce computing concepts and Python programming in a breadth-first manner. Rather than covering computing concepts and Python structures one after another, the book’s approach is more akin to learning a natural language, starting from a small general-purpose vocabulary and then gradually extending it. The presentation is in general problem oriented, and computing concepts, Python structures, algorithmic techniques, and other tools are introduced when needed, using a “right tool at the right moment” model. The book uses the imperative-first and procedural-first paradigm but does not shy away from discussing objects early. User-defined classes and object-oriented programming are covered later, when they can be motivated and students are ready. The last three chapters of the textbook use the context of web crawling and search engines to introduce a broad array of topics. These include foundational concepts such as recursion, regular expressions, depth-first search, and Google’s MapReduce framework, as well as practical tools such as GUI widgets, HTML parsers, SQL, and multicore programming. This textbook can be used in a course that introduces computer science and programming to computer science majors. Its broad coverage of foundational computer science topics as well as current technologies will give the student a broad understanding of the field and a confidence to develop “real” modern applications that interact with the web and/or a database. The textbook’s broad coverage also makes it ideal for students who need to master programming and key computing concepts but will not take more than one or two computing courses, in particular math, science, and engineering majors.
