AttributeError: 'ValueError' object has no attribute 'message'

This error typically occurs when you try to access the 'message' attribute of a ValueError object, but that attribute does not exist.

In Python 3.x, the 'message' attribute was deprecated for exceptions like ValueError. Instead, you can access the error message by converting the exception object to a string, like this:

try:
    # some code that raises a ValueError
except ValueError as e:
    print(str(e))

This will print the error message associated with the ValueError.
