List Data Structures in Python by Pattabhi Rama Mohan Aditya University

1. Python Built-in List (Dynamic Array) The standard list in Python is a dynamic array type. Supports common list operations: indexing, slicing, append, insert, remove, etc. Not a linked list — but often the first “list” data structure students learn in Python. 📌 2. Doubly Linked List (DList) in Python A Doubly Linked List is often referred to as a “DList” in data structures courses. It’s a linear collection of nodes where each node points to both the next and previous node. 🔹 Node Structure Each node typically has: data — value stored in the node next — pointer/reference to the next node prev — pointer/reference to the previous node 🔹 Why Use a Doubly Linked List? Allows traversal in both forward and backward directions. Insertion and deletion at both ends is efficient (given node references). 🔹 Basic Operations Typical operations on a DList include: Insertion at the beginning at the end at a given position Deletion from the beginning from the end from a specific position Traversal forward traversal backward traversal
