Learn PROCESSING-PY with Real Code Examples
Updated Nov 26, 2025
Practical Examples
Animated bouncing ball
Procedural tree generation
Data-driven visualizations
Interactive game prototypes
Generative artwork with algorithmic patterns
Troubleshooting
Ensure proper indentation in Python
Check that Python mode is active in Processing IDE
Use print statements to debug values
Verify assets paths are correct
Restart IDE if sketches fail to run
Testing Guide
Run sketch frequently during development
Test interactions (mouse, keyboard) thoroughly
Verify animations on different screen sizes
Check asset loading correctness
Log performance metrics if needed
Deployment Options
Export desktop applications
Export as Java applet for web (Processing.js)
Share sketches as Python scripts with IDE
Use as teaching examples in classrooms
Bundle sketches with supporting libraries
Tools Ecosystem
Processing IDE
Python mode plugin
Libraries: sound, video, controlP5, toxiclibs
Processing.js for web export
Community examples and sketches
Integrations
Can use Python libraries compatible with Jython
