如何创建在生成特定数字之前生成随机数的链表

import random

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

def createRandomLinkedList(n, target):
    head = ListNode(None)
    curr = head

    for _ in range(n):
        random_num = random.randint(0, target-1)
        while random_num == target:
            random_num = random.randint(0, target-1)
        
        new_node = ListNode(random_num)
        curr.next = new_node
        curr = curr.next
    
    return head.next

n = 10  # 链表长度
target = 5  # 特定数字

linked_list = createRandomLinkedList(n, target)

# 打印链表的值
curr = linked_list
while curr:
    print(curr.val)
    curr = curr.next
