Learn Python Visually

Look Inside!

Download Chapter 9: FUNCTIONS AND PERIODIC MOTION

The perfect book for first-time programmers, Learn Python Visually introduces the fundamentals of computer coding within a visual, graphics-based context. Tristan Bunn’s creative teaching approach will help you visualize core programming concepts as you make cool pictures, animations, and simulations using Python Mode for the open source Processing development environment.

From the very first chapter, you’ll produce and manipulate colorful designs as Bunn walks you through a series of easy-to-follow graphical coding projects that grow increasingly complex. You’ll progress from drawing with code to animating a bouncing DVD screensaver to creating interactive programs. Along the way, you’ll encounter skill-building challenges on topics as diverse as video games, coffee, fine art, amoebas, and Pink Floyd.

You’ll learn how to:

• Apply basic coding theories and concepts, like variables, data types, pixel coordinates, control flow, and algorithms
• Write code that produces drawings, patterns, animations, data visualizations, user interfaces, and simulations
• Use code to explore randomness, handle CSV and JSON data, and generate animations that employ trigonometry for periodic motion and Lissajous curves
• Define functions, reduce repetition, and make your code more modular
• Write classes and create objects to structure code more efficiently

If you’ve ever dreamed of coding for data visualizations, computer-generated art, games, or other creative technologies, Learn Python Visually is the entry point you need.
