Fetching Last n Items of an Iterable: In order to fetch the last n items of an iterable, you can use slicing with a negative index. Slicing is a handy way to quickly access parts of an iterable, and is a very fast operation.
Fetching Last n Items of an Iterable
Say you have a list of 10 numbers added sequentially, and you need to retrieve the most recently added 5 elements, then you would write listOne[-5:] to serve the purpose. This can be read as "5th from end to end."
>>> listOne = [2, 6, 9, 2, 5, 3, 6, 10] >>> listOne[-5:] [2, 5, 3, 6, 10]
