Delete Node in Linked List in Python (Example)

In this tutorial, you’ll learn how to delete a node in a linked list using the Python programming language.

Let’s dive into it!

Introduction to Deleting a Node in a Linked List

A linked list is a data structure where each element, known as a node, contains a value and a reference to the next node in the sequence. Deleting a node in a linked list involves removing a specific node from the list and reorganizing the links to maintain the integrity of the list.

Deleting a Node in a Linked List

To delete a node in a linked list in Python, you can follow these steps:

Step 1: Traverse the linked list to find the node to be deleted.

Step 2: Update the links to bypass the node to be deleted.

Step 3: Free the memory occupied by the deleted node (In Python garbage collection is done automatically)

Here’s an example of deleting a node in a linked list:

class Node:
    def __init__(self, value):
        self.value = value = None
def delete_node(head, value):
    if head is None:
        return head
    if head.value == value:
    current = head
    while is not None:
        if == value:
        current =
    return head

In the above code, we define a class Node to represent a node in the linked list. The delete_node function takes the head of the linked list and the value of the node to be deleted as parameters. It traverses the linked list and updates the links to bypass the node with the specified value. Finally, it returns the updated head of the linked list.

If the entered value isn’t found in the linked list, no exception is raised, and the linked list is returned without any alterations. Also, the implementation is slightly different if our linked list is a doubly linked list or a circular linked list, which you can check out in our tutorials about their implementations.

Let’s see it in an example!


In this example, first, I will create a linked list, then I will remove a node from it.

# Create a linked list
head = Node(10)
node2 = Node(20)
node3 = Node(30) = node2 = node3
# Delete a node with value 20
head = delete_node(head, 20)
# Print the updated linked list
current = head
while current is not None:
    current =
# 10
# 30

Above, we create a linked list with three nodes and delete the node with the value 20. The resulting linked list is then printed.
