The zyBooks version of the Data Structures & Algorithms in Python textbook provides a powerful interactive learning environment

The Data Structures & Algorithms in Python zyVersion contains the complete 1st edition content of the authors’ object-oriented Python data structures book, which is based on their market-leading data structure books in Java and C++.

  • Offers a comprehensive introduction to data structures and algorithms, including their design, analysis, and implementation
  • Includes over 50 interactive animations that enhance learning with step-by-step dynamic illustrations of algorithms, data structure operations, and other key concepts
  • Includes over 150 question sets embedded throughout the book that provide immediate feedback to learners, plus over 750 end-of-chapter exercises
  • Extensive Python source code is consistent with standard Python APIs; the entire codebase is available online

Co-author Professor Michael Goldwasser demonstrates the power of an interactive approach to data structures:

What is a zyVersion?

zyVersions are leading print titles converted and adapted to zyBooks’ interactive learning platform, allowing for a quick and easy transition to an engaging digital experience for instructors and students.

zyBooks’ web-native content helps students visualize concepts to learn faster and more effectively than with a traditional textbook. (Check out our research.)

This zyVersion of Data Structures & Algorithms in Python benefits both students and instructors:

  • Instructor benefits
  • Customize your course by reorganizing existing content or adding your own
  • Continuous publication model updates your course with the latest content and technologies
  • Robust reporting gives you insight into students’ progress, reading and participation
  • Animations and other interactive content can be shown in presentation mode and used during a lecture
  • Student benefits
  • Learning questions and other content serve as an interactive form of reading
  • Instant feedback on homework
  • Concepts come to life through extensive animations embedded into the interactive content
  • Save chapters as PDFs to reference the material at any time
