How do I implement a doubly linked list in Python?

To implement a doubly linked list in Python, you need to create a Node class and a DoublyLinkedList class.

Can you show me the code for the Node class?

Sure! Here's a simple implementation of the Node class:

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

What about the DoublyLinkedList class?

The DoublyLinkedList class will manage the nodes. Here's a basic structure:

class DoublyLinkedList:
    def __init__(self):
        self.head = None
        self.tail = None

How do I add a new node to the list?

You can add a new node by creating a method in the DoublyLinkedList class. Would you like to see an example?
