python - 链表中的显示方法不显示整个列表项

Question

我是 python 的初学者，我想创建一个单链表，然后在列表的末尾添加一个节点。但我有一个问题......当我想显示列表中的项目时，它会显示我插入的最后一个节点的值。我应该怎么做才能解决这个问题？？

class Node:
    def __init__(self, value):
        self.info = value
        self.link = None


class SingleLinkedList:
    def __init__(self):
        self.start = None

    def create_list(self):
        n = int(input('enter number of nodes '))
        if n == 0:
            return
        for i in range(n):
            b = int(input('enter the element to be inserted '))

    def insert_at_end(self, data):
        temp = Node(data)      #insertion in the empty linked list
        if self.start is None:
            self.start = temp
            return

        p = self.start
        while p is not None:
            p = p.link
        p.link = temp

    def display_list(self):
        if self.start is None:
            print('linked list is empty')

        else:
            print('list is: ')
            p = self.start
            while p is not None:
                print(p.info, "", end='')
                p = p.link
            print()


test = SingleLinkedList()
test.create_list()
data = 70
test.insert_at_end(data)
test.display_list()
