Instant-feedback, instant-debugging Python coding
summary
A working prototype runs code after every keystroke and places per-line program state next to the source, eliminating print statements, logs and context switches. It overrides the built‑in Python debugger to track execution continuously, demonstrates binary search with live iterations, fetches images via requests behind a cache to avoid repeated network hits, and simulates a PID‑controlled Segway where tuning P/I/D visibly stabilizes and then drives the model — the demos are interactive and they work.
