I am running Python via Pyscript and my code used to work fine for around 1 year. However its no longer working and I get the following error message
JsException(PythonError: Traceback (most recent call last):

I don't know how to fix it so Ive not tried anything yet.
My Code is below:

UPDATE:
I updated the PyScript to the latest one: https://pyscript.net/latest/pyscript.js
And Now I get a different Error, the error is:
UserError: (PY9000): The use of top-level "await", "async for", and "async with" has been removed.
Please write a coroutine containing your code and schedule it using asyncio.ensure_future() or similar.
See https://docs.pyscript.net/latest/guides/asyncio.html for more information.
I think this error is more specific however, I have no idea what a coroutine is, any help will be highly appreciated.
UPDATE 2:
I created a coroutine and I got a error saying
No module named 'panel'
So to conclude I created this script when PyScript was in its Beta stage, and the code samples Ive used to create the script have been updated. So I will be recreating the script with the new code examples provided and hopefully fix the issue.
