Solution

Here is a step-by-step solution to reverse a linked list in Python:

  1. Define a class Node with a constructor that initializes the data and next attributes. The data attribute stores the value of the node and the next attribute points to the next node in the linked list.
class Node:
    def __init__(self, data=None):
        self.data = data
        self.next = None
  1. Define a class LinkedList with a constructor that initializes the head attribute. The head attribute points to the first node in the linked list.
class LinkedList:
    def __init__(self):
        self.head = None
  1. In the LinkedList class, define a method append that adds a new node to the end of the linked list.
    def append(self, data):
        if not self.head:
            self.head = Node
