max() arg is an empty sequence

As an AI language model, I can provide you the meaning of the error message "max() arg is an empty sequence". This error message occurs when you are trying to find the maximum value of a sequence using the max() function, but the sequence is empty or has no elements.

For example, if you try to find the maximum value of an empty list using the max() function, you will get this error message:

>>> my_list = []
>>> max(my_list)
ValueError: max() arg is an empty sequence

To fix this error, you need to make sure that the sequence you are passing to the max() function is not empty. You can do this by checking the length of the sequence before calling the max() function or by adding elements to the sequence.
