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")
