In this video, we very briefly introduce the notion of the "linked list", specifically the "singly linked list" data structure. It is assumed that the viewer is somewhat familiar with this concept and has been exposed to it at some earlier level, for instance in the context of a computer science course, etc.

We review the basic trade-offs of linked lists versus arrays, and then we proceed to describe and program how one may insert data into a linked list. We investigate three different insertion methods:

- Append (add element to end of list)
- Prepend (add element to beginning of list)
- Add element after element in the list.

We proceed to implement these methods in Python.
