Negative indexing starts from the end. It can be more convienient at times to use negative indexing to get the last item in the list because you don’t have to know the length of the list to access the last item. The first item, the string 'shark' starts at index 0, and the list ends at index 4 with the item 'anemone'.. Because each item in a Python list has a corresponding index number, we’re able to access and manipulate lists in the same ways we can with other sequential data types.
