Live Programming Mode - Python Tutor - Visualize Python and JavaScript code

This is the live programming mode (video intro), which continually runs and visualizes your code as you type. It's highly experimental and does not yet support all languages and features of the regular Python Tutor visualizer.

This live programming mode of Python Tutor (code on GitHub) supports three languages: Python 2.7 and 3.6 with limited module imports, and JavaScript running in Node.js v6.0.0 with limited support for ES6. Try the regular Python Tutor visualizer for additional language support.
