Vermin

Vermin is a static analysis tool that concurrently detects the minimum Python versions required to run code. It is an actively maintained project with frequent updates, often adding support for the latest Python versions (e.g., 3.14, 3.13, 3.12) and expanding its rule set. It functions by parsing Python code into an abstract syntax tree (AST) and matching it against an extensive internal database of Python language features.
