en Limba Engleză Hardback – 30 Sep 2014
This text helps beginners develop their own Python programs. Experiments with fully completed programs are provided at the beginning of each chapter, allowing instructors to use the text in CS0 courses where students do not learn programming. Programming projects appear later in each chapter. Students are encouraged either to write the code that implements the functions introduced earlier or extend the existing programs. All the projects push students to explore further on their own.

Recenzii

This entry-level computer science textbook is intended for use in an introductory course for computer science majors or non-majors desiring an overview of the basic concepts and processes of computer programming. … Each chapter contains illustrations and code examples as well as a tutorial project that walks the student step-by-step through a task-related programming activity. Access to online resources, including a lab manual and links to the latest version of the open source Ruby software, is provided.
