用pyhton爬虫，为什么会报错啊

用代码块功能插入代码，请勿粘贴截图

import requests
from bs4 import BeautifulSoup
import re
import pandas as pd
import numpy as np

url = 'http://quotes.money.163.com/data/caibao/yjgl_ALL.html?'

def get_html(url):
    headers = {'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, likeGecko) Chrome/87.0.4280.88 Safari/537.36'
    }

    res = requests.get(url,headers=headers)
    res.encoding = 'utf-8'
    return res.text
html= get_html(url)
soup = BeautifulSoup(html, 'html.parser')

stock_list = soup.find('table',attrs={'id':'plate performance'})
print(stock_list)
    
items = stock_list.find_all('td')
    
for item in items:
    url = item.a['href']
    id = re.find_all(attrs={'target':'_blank'}) 
    stock_id_list.append(id)
print(stock_id_list) 


、、、

AttributeError: 'NoneType' object has no attribute 'find_all'
###### 我的解答思路和尝试过的方法 

###### 我想要达到的结果

你在find_all('td')标签时，没有找到td标签，你把stock_list打印出来后，看看哪个标签是你想要的数据，把td换一下。
