Linked List Node

Write a simple Linked List Node in python

A linked list is either:

• the empty list, represented by None, or

• a node that contains a cargo object and a reference to a linked list.

  #! /usr/bin/env python

  class Node: def init(self, cargo=None, next=None): self.car = cargo self.cdr = next
  def str(self): return str(self.car)

     def display(lst):
         if lst:
            w("%s " % lst)
            display(lst.cdr)
         else:
            w("nil\n")
