# Insert A Node At End In Linked List using Python

Technology and generation are growing up together, and the younger generation users are somewhat connected with tech and the internet all the time. Not to mention, today the whole world in this time of crisis is working over the internet. But to make these technologies, software, etc a software developer must have excellent problem-solving skills. In this world where the internet is the new fuel, one needs to be pretty sharp. And by sharp, for software developers, it means knowing how to automate real-world problems using computer programs. Data structures help a lot in this journey of logic building. So today we’re going to write a simple data structure program to Insert A Node At the End In Linked List using Python.

## What is A Linked List?

A linked list is a basic list of nodes containing different elements for all algorithms in data structures. Also, it’s pretty easy to understand.

## What’s The Approach?

• Firstly we’ll allocate a new node, by simply creating it.

• Next up we’ll insert the data in this new node.

• Now, the `next` section of the node is set to null showing the end of the linked list.
• Also,o the `next` section of our linked list is going to point towards the head of this newly created node.

## Python Program To Insert A Node At End In Linked List

Input:

`append(6)`

`push(7)`

Output:

`Created Linked List is: 7 6`

```# Python program to demonstrate all
# insertion methods of linked list at the end

# Node class
class Node:

# Function to initialise the node object
def __init__(self, data):
self.data = data # Assign data
self.next = None # Initialize next as null

# Linked List class contains a Node object

# Function to initialize head
def __init__(self):

# Functio to insert a new node at the beginning
def push(self, new_data):

# 1 & 2: Allocate the Node &
#	 Put in the data
new_node = Node(new_data)

# 3. Make next of new Node as head

# 4. Move the head to point to new Node

# This function is defined in Linked List class
# Appends a new node at the end.
def append(self, new_data):

# 1. Create a new node
# 2. Put in the data
# 3. Set next as None
new_node = Node(new_data)

# 4. If the Linked List is empty, then make the
# new node as head
if self.head is None:
return

# 5. Else traverse till the last node
while (last.next):
last = last.next

# 6. Change the next of last node
last.next = new_node

# Utility function to print the linked list
def printList(self):
while (temp):
print temp.data,
temp = temp.next

# Driver Code
if __name__=='__main__':

# Insert 6. So linked list becomes 6->None
llist.append(6)

# Insert 7 at the beginning. So linked list becomes 7->6->None
llist.push(7);

print 'Created linked list is:',
llist.printList()

```
