Other than the "breakloop" functionality, which I agree is (AFAIK) unique to Lisp interpreters, I don't see anything described there that can't be done in a Python REPL.
If you can't understand what people are trying to say, I recommend trying to experience it for yourself. Install Common Lisp along with Slime for Emacs, and try things out. Or try out a Smalltalk environment like Squeak or Pharo which would also give you the same "enlightening" experience.
I know you are skeptical because python has a repl too and so it is hard to see what these "live" environments like lisp/smalltalk are offering. But trust me (and the others) that there is more than what python offers.
I have written python professionally probably more than any other language I have used, so I'm not ignorant of python btw.
No one is trying to fool you. But you don't have to take our word, please try it out for yourself!
> If you can't understand what people are trying to say
I understand it just fine. I've used a Lisp REPL. I'm just pointing out that not all of the features of the Lisp REPL that are being mentioned are unique to Lisp.
> I know you are skeptical
I'm not "skeptical" at all about what can be done in a Lisp REPL. As I just said, I've used it. I have not claimed that a single thing anyone has said about the Lisp REPL is false.
I think you are reading things into my posts that I have not said.
> you don't have to take our word, please try it out for yourself
As I said above, I already have. Don't jump to conclusions.
