👉Code for execution:
class Node:
def __init__(self, data):
self.data = data
self.next = None
Creating nodes
node1 = Node(10)
node2 = Node(20)
node3 = Node(30)
node4 = Node(40)
Connecting nodes
node1.next = node2
node2.next = node3
node3.next = node4
Adding a new node at the beginning
head=node1
new_node = Node(50)
new_node.next = head
head = new_node
