 <li>You can get a part of a list, called a &#8220;slice&#8221;, by specifying two indices. The return value is a new list containing all the items of the list, in order, starting with the first slice index (in this case <code>a_list[1]</code>), up to but not including the second slice index (in this case <code>a_list[3]</code>).
 <li>Slicing works if one or both of the slice indices is negative. If it helps, you can think of it this way: reading the list from left to right, the first slice index specifies the first item you want, and the second slice index specifies the first item you don&#8217;t want. The return value is everything in between.
