Let's test your linked list by creating three nodes and a linked list object. Let's convert the first node as the head node of the list.

Here’s a slight change to the linked list’s __init__ () that allows you to quickly create linked lists with some data: def __init__(self, nodes=None): self.head = None if nodes is not None: node = Node(data=nodes.pop(0)) self.head = node for elem in nodes: node.next = Node(data=elem) node = node.next.
