Python Program to Create and Display Linked List

Linked lists are fundamental data structures in computer science, offering a dynamic way to organize and manage data. In this context, we will explore a Python program that constructs and exhibits a linked list, demonstrating the principles of this data structure.

Problem Statement

Compose a Python program to create and exhibit a simple linked list. The program should illustrate the process of building a linked list by sequentially adding elements, and then display the linked list’s contents.

Python Program to Create and Display Linked List

class Node:
    def __init__(self, data):
        self.data = data
        self.next = None

class LinkedList:
    def __init__(self):
        self.head = None
    
    def append(self, data):
        new_node = Node(data)
        if self.head is None:
            self.head = new_node
            return
        current = self.head
        while current.next:
            current = current.next
        current.next = new_node
    
    def display(self):
        current = self.head
        while current:
            print(current.data, end=" -> ")
            current = current.next
        print("None")

# Create a linked list
my_linked_list = LinkedList()
my_linked_list.append(3)
my_linked_list.append(7)
my_linked_list.append(10)

# Display the linked list
print("Linked List:")
my_linked_list.display()
