Here's an overview: https://lisp-journey.gitlab.io/pythonvslisp/ https://lisp-journey.gitlab.io/pythonvslisp/ In short, the Python process has to restart to take changes in, and you loose your objects in the REPL. The Lisp process doesn't and is built to (lazily) update your objects to reflect structure changes (such as if you deleted a class slot). I particularly like the Lisp way for unit tests or the web.
