#In Python we deal with data structures like lists,

#but we don't talk much about how lists are implemented

#by Python itself.

#

#One way in which lists can be implemented is with what

#is called a Linked List. In a Linked List, a list is

#made of a series of items. Each item contains two

#elements: its own value $($node$.$value$),$ and a pointer to

#where to find the next element in the list

#$($node$.$next$\_$node$).$ So$,$ you can't jump right in to

#"item $7"$; you instead have to start with the first

#item and keep getting the next item until you reach the

#seventh item.
