Since cloud logs are down, are there any semi-easy methods using Python to detect when a value of from any cloud variable on a project is changed with minimal delay? I have heard web sockets may work but I haven’t seen anyone confirm it truly does. From what I have seen, there doesn’t seem to be any way at all on Scratchattach to use any get variable function or event without cloud logs; although setting variables seems to be fine. Everyone please also post or link some example Python code that still works and relates to this problem so I can examine it. Furthermore, if it is possible, with the same or different method, is there a way to see which player changed that variable, and if not, it’s okay, I’ll just do more work coding.

You probably don't need this now that cloud logs work, but scratchattach has a WsCloudEvents class. It's similar to CloudEvents but uses websockets instead of cloud logs. The constructor takes a CloudConnection as a second argument:
It doesn't tell you which user changed the variable.
