How do i add an item to the end of a linked list? : class Node:
    def __init__(self, item, next):
        self.item = item
        self.next = next

class LinkedList:
    def __init__(self):
        self.head = None

    def add(self, item):
        self.head = Node(item, self.head)

    def is_empty(self):
        return self.head == None

I tried doing it this way but it doesn't work.

from LinkedList import Node, LinkedList

def insert_at_end(linked_list, item):
    linked_list.add(item)

Can anyone help?
