Computer Programming Step by Step guides learners with little to no experience in writing computer programs using the Python programming language. It supports learners in the development of an experiential grasp of computer programming and provides a strong foundation upon which to further their knowledge.This guide provides practical experience of programming concepts, including writing, editing, and troubleshooting programs. It focuses on a powerful subset of Python statements that allow the reader to write programs to solve a wide variety of programming problems and understand the nature of computer programming at a deep level. It links conceptual explanations with perceptual recognition, the visual signals that show how each Python statement changes the underlying computer that executes it, with the systematic use of PythonTutor to ground a learner's understanding in concrete experience.With over 300 visuals and a clever use of storyboards, Josh Tenenberg guides learners through each step with clarity and supports the development of hands-on experience.This is an open access title available under the terms of a CC BY-NC-ND 4.0 International licence.
