There is https://github.com/quil-lang/sbcl-librarian which relies on a recent https://www.sbcl.org/manual/#Calling-Lisp-From-C If SBCL is the preferred Lisp then this route can be pursued - I don't however know enough about FriCAS to see how to use sbcl-librarian to call FriCAS functions from Python. (There doesn't even seem to be an example on calling FriCAS from its underlyng Lisp available anywhere - from that it should be doable) I don't think it can be totally Lisp-agnostic: SBCL does not allow embedding in the way ECL does (It's Embeddable Common Lisp for a reason...)
