Where n is the length of the array, n - 1 will be the index value of the last item. Note that you can also access each individual element using negative indexing. With negative indexing, the last element would have an index of -1, the second to last element would have an index of -2, and so on.

python - How do I get the last element of a list? - Stack Overflow

some_list[-1] is the shortest and most Pythonic. In fact, you can do much more with this syntax. The some_list[-n] syntax gets the nth-to-last element. So some_list[-1] gets the last element, some_list[-2] gets the second to last, etc, all the way down to some_list[-len(some_list)], which gives you the first element.. You can also set list elements in this way.
