maxarg is an empty sequence

The error message "maxarg is an empty sequence" indicates that you are trying to find the maximum value in an empty sequence, such as an empty list or tuple. In Python, you can use the built-in max() function to find the maximum value in a sequence.

For example, if you have a list of numbers:

my_list = [1, 2, 3, 4, 5]

You can find the maximum value using the max() function:

max_value = max(my_list)
print(max_value) # Output: 5

However, if the list is empty:

my_empty_list = []

Then calling max() on it will result in the "maxarg is an empty sequence" error:

max_value = max(my_empty_list)
# Output: ValueError: max() arg is an empty sequence

To avoid this error, you can check if the sequence is empty before calling max():

if my_empty_list:
    max_value = max(my_empty_list)
else:
    max_value = None
