I don't know where you got that impression, but CL development is no different than Python development. Code goes in .lisp files, and then you either load it into the REPL or pass it to the compiler and tell it what the entry point is. I suppose it's technically possible to develop an entire application at the REPL and then dump to a binary, but I don't think anybody does that any more than they do it in Python.
