在python链表中添加不同的信息并打印出来

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

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

        self.head = new_node
        self.tail = new_node
    else:
        self.tail.next = new_node
        self.tail = new_node

# 创建链表对象
my_list = LinkedList()

# 添加节点
my_list.add_node("信息1")
my_list.add_node("信息2")
my_list.add_node("信息3")

# 打印链表
my_list.print_list()

信息1
信息2
信息3
