pdit: Python Un-Notebook

pdit is a Python Un-Notebook: an output-focused Python editor for plain .py files. Run code statement by statement and see output inline beside the exact line that produced it, with notebook-like iteration but no notebook cells, no notebook file format, and no conversion step. The workflow is expression-first, so top-level expressions render by default and intermediate states stay visible. Keep pdit open while Claude Code, Cursor, or similar tools edit your script on disk.
