Multiple infinite loops in python?

Question

Python

Sorry for the dumb question, I'm new. I am making a parser (sends a request to the server, receives a response and writes it to the table at the click of a button). The data must be updated dynamically (that's why I have the parsing function in an infinite loop). Everything hangs. Used multiprocessing. Maybe I wrote something wrong, maybe it's just impossible to do it that way. Tell me what you can think of

Answer 1

In any infinite loop, there must be a forced exit on the brake. Check if you have it.
