A Lean Proof Printing Python Union Find
Philip Zucker shows how a Python union-find data structure can generate Lean proof certificates, turning union and path-compression operations into machine-checkable equality proofs. He uses the experiment to explore the broader idea of treating proofs as traces of search, with applications to e-graphs and theorem-proving systems.

Hey There Buddo!
A Lean Proof Printing Python Union Find
It is somewhat strange, but I haven’t really spent much time working on proof production or recording out of egraphs.
Anyone still using Flask, or has FastAPI completely taken over? 🤔

Why You NEED This New Python Tool
Pyrefly is Meta’s open-source static type checker for Python, designed to catch type-related bugs before code runs instead of waiting for runtime failures. The video explains why Python and type hints alone can miss these errors, and shows how Pyrefly detects them early in real-world codebases.
