使用Python在SortedLinked列表中插入新值？

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

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

    def insert(self, value):
        new_node = Node(value)

        if self.head is None:
            self.head = new_node
            self.tail = new_node
            return

        if value < self.head.value:
            new_node.next = self.head
            self.head = new_node
            return

        current = self.head
        while current.next is not None and value > current.next.value:
            current = current.next

        new_node.next = current.next
        current.next = new_node

        if current == self.tail:
            self.tail = new_node

    def display(self):
        current = self.head
        while current is not None:
            print(current.value, end=" ")
            current = current.next
        print()

# 示例用法
linked_list = SortedLinkedList()
linked_list.insert(3)
linked_list.insert(1)
linked_list.insert(5)
linked_list.insert(2)
linked_list.display()
