insertAtBegin method is not working in double linked list in your solution.

Hello,

Thanks for the lesson on linked list. I understood it completely.

This should work. Please update.

def insertAtBegin(self, data):
if self.head is None:
node = Node(data, self.head, None)
self.head = node
return
node = Node(data, self.head, None)
node.next = self.head
self.head.prev = node
self.head = node
