有没有大哥知道下面的代码出了什么问题

import requests
import bs4

url = 'https://psychology.ku.dk/staff/academic_staff/'

headers = {'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/95.0.4638.54 Safari/537.36'}

response = requests.get(url, headers=headers)

soup = bs4.BeautifulSoup(response.text, 'html.parser')

name_targets = soup.find_all('td', class_=('emplistname', 'sorting_1'))
names=[]
for each in name_targets:
    name = each.a.text
    names.append(name)

title_targets = soup.find_all('td', class_="emplisttitle")
titles = []
for each in title_targets:
    title = each.text
    titles.append(title)
   
area_targets = soup.find_all('td', class_="emplistworkarea")
areas = []
for each in area_targets:
    area = each.text
    areas.append(area)
   
mail_targets = soup.find_all('td', class_="emplistemail")

a标签没有title这个属性

1. <a href="#" onclick="this.href=&#39;mai&#39; + &#39;lto:&#39; + &#39;ann-louise.holten&#39;+&#39;@&#39;+&#39;psy.ku&#39;+&#39;.&#39;+&#39;dk&#39;;return true;" onmouseover="this.[title=&#39;ann-louise.holten&#39;+&#39;@&#39;+&#39;psy.ku&#39;+&#39;.&#39;+&#39;dk&#39;; return true;">E-mail</a>
