In the previous lesson, we defined our Node and LinkedList classes. In this lesson, we’ll implement the class methods to insert elements in a linked list:

append

prepend

insert_after_node

Append

The append method will insert an element at the end of the linked list. Below is an illustration which depicts the append functionality:

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

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

  def append(self, data):
    new_node = Node(data)
    if self.head is None:
      self.head = new_node
      return
