When it is required to print the specific node from the end of a linked list, the methods ‘list_length’ and ‘return_from_end’ methods are defined. The ‘list_length’ reutrns the length of the linked list.The ‘return_from_end’ method is used to return the nth element from the end of the linked list.Below is a demonstration for the same −Example Live Democlass Node:    def __init__(self, data):       self.data = data       self.next = None class LinkedList_structure:    def __init__(self):       self.head = None       self.last_node = None    def add_vals(self, data):       ...
