# Python Programming Examples on Linked Lists

Here is the listing of Python programming examples on Linked Lists.

## 1. Python Examples on Creating and Displaying the Elements of a Linked List

A linked list consists of nodes, each node consists of a value and a pointer to another node. Starting node of a linked list is referred to as the header. linked list is a chain of values connected with pointers. This section contains Python Programs on creating a linked list using data items input from the user and displays it. It also contains program to read a linked list in reverse using singly linked list.

## 2. Python Examples on Search and Display Functions of a Linked List

This section contains Python Programs on searching an element in a linked list with and without using recursion, program to display the nodes of a linked list in reverse with and without using recursion. Search function searches for the specified element in the linked list. Display function is used to display the elements of the linked list. Function calls itself is knows as recursion.

## 3. Python Examples on Implementation of Count, Length and Print Operations on a Linked List

The Python programs in this section performs operations like counting, finding length and printing the elements of the linked list. The Python programs to find the length of a linked list with and without using recursion, program to count the number of occurrences of an element in a linked list with and without using recursion, program to print the alternative nodes in a given linked list with and without using recursion.

## 4. Python Examples on Implementation of other Data Structures using Linked List

Stack works on the principle of Last In First Out (LIFO). Queue works on the principle of First In First Out (FIFO). A binary tree is a structure that has a root and in which each vertex has no more than two children. Each child of a vertex is called a left or right child. The Python programs in this section deals with the implementation of stack, queue and binary tree using linked lists.

## 5. Python Examples dealing with the Operations on the Elements of a Linked List

The Python programs in this section to find largest element in a doubly linked list, detecting the cycle in a given linked list, program to check whether given 2 linked lists are same or not, program to add elements in a linked lists, program to find first common element in a given 2 linked lists, program to find number of occurrences of all elements in a linked list.

## 6. Python Examples on Print, Reverse and Read Operations

The Python programs in this section performs print, reverse and read operations like removing duplicates from the given linked list, program on reversing the given linked list, reversing only first n elements in a given linked lists, printing the middle most node or last node from the given linked lists.

## 7. Python Examples on Binary Tree Implementation using Linked List

Binary tree is a tree-like structure that has a root and in which each vertex has no more than two children. Implementing a binary tree is complex. The first and last node of a linked list are known as the head and tail of the list. By starting at the head, and moving from one node to another by following each node’s next reference, we can reach the tail of the list. We can identify the tail as the node having None as its next reference. This process is commonly known as traversing the linked list. Process of traversing a list is also known as link hopping or pointer hopping. This section contains Python programs to find intersection and union of 2 linked lists, converting binary tree to singly linked list by traversing and construct a balanced binary search tree using doubly linked list.

Python Program to Find Intersection & Union of 2 Linked Lists Python Program to Convert a Binary Tree into a Singly Linked List by Traversing Level by Level Python Program that takes an Ordered Binary tree & Rearranges the Internal Pointers to make a Circular Doubly Linked List out of the Tree Nodes Python Program to Construct a Balanced Binary Search Tree which has same data members as the given Doubly Linked List |

## 8. Python Examples on Interchange and Modify Operations

Josephus problem or Josephus permutation is a theoretical problem related to a certain counting-out game. This section contains Python program to solve josephus problem using circular linked list, program to interchange two elements in a list without using key field, programs on modifying the given linked list, programs to interchange the adjacent nodes in a given circular linked list.

## 9. Python Examples on Singly Linked Lists

A singly linked list is a collection of nodes that collectively form a linear sequence. Each node stores a reference to an object that is an element of the sequence, as well as a reference to the next node of the list. This section contains Python Programs on singly linked list operations, program to check whether given singly linked list is a palindrome or not, program to convert a given singly linked list into circular list.

## 10. Python Examples on Circularly & Doubly Linked Lists

Circular list is a linked list where the endpoints are connected. That is, the last node in the list points back to the first node. Circular lists can be based on both singly and doubly linked lists. linked list in which each node keeps an explicit reference to the node before it and a reference to the node after it. Such a structure is known as a doubly linked list. This section contains Python Programs on implementing circular single and doubly linked list, implementing doubly linked list using singly linked list, performing doubly linked list operations like insertion, deletion and display.
