ROOT https://root.cern.ch/ https://root.cern.ch/ provides Python bindings through its PyROOT functionality. It builds the bindings (ROOT calls them "dictionaries") by parsing your C++ using their "cling" interpreter based on LLVM. As far as usability, ROOT is a big package but once a given it's rather easy and non-intrusive to create Python bindings for your C++.
