User-defined lists serve as an illustration of how to implement a linked list data structure in Python. The chapter explores creating nodes, appending, inserting, and deleting nodes from a list while following recursive and iterative approaches. Additionally, the importance of understanding node connections and memory management when performing these operations is emphasized.

What we have learnt
- A linked list consists of nodes, each storing a value and pointing to the next node.
- An empty list is represented as a single node with its value and pointer set to none.
- Appending, inserting, and deleting nodes involves careful management of pointers to maintain the integrity of the list structure.
Key Concepts
-
Term: Node
Definition: A basic unit of a data structure, which in the context of a linked list contains a value and a reference to the next node.
-
Term: Linked List
Definition: A data structure consisting of a sequence of nodes where each node points to the next node in the sequence.
-
Term: Append
Definition: The operation of adding a new node with a specified value at the end of the linked list.
-
Term: Insert
Definition: The operation of adding a new node at the beginning or a specified position of the linked list.
-
Term: Delete
Definition: The operation of removing a node from the linked list based on a specified value.
