Is it a linkedlist ?

Question

#Linked list
class Node:
def __init__(self, data, nxt=None):
self.data = data
self.nxt = nxt
class LinkedList:
def __init__(self):
self.head = None;
def insert(self, data):
if (not self.head):
self.head = Node(data)
else:
last_node = self.head
self.head = Node(data)
self.head.nxt = last_node
def output(self):
node = self.head
while node:
print(node.data, end=' -> ')
node = node.nxt
print(None)
lnkdLst = LinkedList()
lnkdLst.insert(1)
lnkdLst.insert(5)
lnkdLst.insert(9)
lnkdLst.insert(13)
lnkdLst.output()

Answer 1

I am not sure . But I think it is the way how linked List is implemented in python
