Is there away to use ValueError terminal output?

Question

I was wondering if there is a way to use the terminal output for ValueError when found? In my case, it works perfectly as is. See attached image. If I could just display it on my GUI, it would instantly improve my UX. I can't imagine having to write codes to capture the error in question '*5'. Does it have something to do with message.py? How do I get there?

on my wish list

In general, this is how you catch and print an exception:

try:
    # doing something that raises an error
    a = float('*5')
except ValueError as e:
    error_msg = repr(e)  # this is the error message
    print('Got a ValueError exception!')
    print(error_msg)
