-Accessing a List Item

Through referring to the index, you may pick a specific list object. Note, Python uses zero-based indexing, so continue counting at 0 while you do this.

Now, to figure out what the second item in the planet list is, do this:

You may also pick a set of objects by listing two indexes separated by a column. Just like this:

Remember that this does not necessarily contain the upper index specified? I stated 1:3, but it returned only two values. It is since Python just returns the list items to, but does not include, the last listed table.

-Negative indexing

You should continue numbering from the end of the list using a negative index. In this scenario, the count must continue at-1 (not zero). So the index of-1 is the last item,-2 is the second item, and so on.
