A linked list (like the chains we see – always has a head, right?), so I can define my linked list with a head value which basically is just another node (ring): ll = LinkedList(e1) I can now define a linked list since I have my nodes ready. If I have two values – say 1 and 2 – and I want to add them to the list, the first thing is to define them as individual nodes (that is, as rings of a chain). The append() method lets you add a new node to the list. Next we are going to define some basic functions: class LinkedList: The next means that it is possible we want to chain other nodes – I mean, that is the major aim of a linked list. We add the value because for anything to be added to the linked list, it should at least have some value (for example, except in rare situations, you don't add an empty string to an array, right?). So let's create the nodes first: class Node: I will be using this to illustrate as we go.so you can think along these lines (this is not an art class – I repeat, this is not an art class :) ). Joe is here with some rings, and he is going to help us. Remember that a Linked List is similar to how a chain is coupled together. What differentiates the head (which is the first node in the list) is that you gave it the title head, and then you started adding other nodes to it. You just have to realize that every item that you will be adding to the list is just a node (similar to a ring in a chain). It's something that helped me understand it much better. Here's a trick when creating a Linked List. The most important thing is to understand how it works. We'll do this using Python, but most of what we learn here applies to any language you are using. Now with all the theory out of the way, it's time to implement one. These are a few things you should consider before trying to implement a linked list.
