Of all the sequences, lists are the easiest to understand and are the most directly related to a real-world object. Working with lists helps you become better able to work with other kinds of sequences that provide greater functionality and improved flexibility. The point is that the data is stored in a list much as you would write it on a piece of paper — one item comes after another, as shown in Figure 13-1. The list has a beginning, a middle, and an end. As shown in the figure, the items are numbered. (Even if you might not normally number them in real life, Python always numbers the items for you.)
