For loop 用于为多个URL抓取电子邮件的For循环-BS

下面是为单个基本url抓取电子邮件的代码，我一直在绞尽脑汁寻找一个简单的“for-loop”来为url数组或将url列表（csv）读入python。任何人都可以修改代码以便它可以完成任务吗

import requests
import re
from bs4 import BeautifulSoup

allLinks = [];mails=[]
url = 'https://www.smu.edu.sg/'
response = requests.get(url)
soup=BeautifulSoup(response.text,'html.parser')
links = [a.attrs.get('href') for a in soup.select('a[href]') ]

allLinks=set(links)
def findMails(soup):
    for name in soup.find_all('a'):
        if(name is not None):
            emailText=name.text
            match=bool(re.match('[a-zA-Z0-9_.+-]+@[a-zA-Z0-9-]+\.[a-zA-Z0-9-.]+$',emailText))
            if('@' in emailText and match==True):
                emailText=emailText.replace(" ",'').replace('\r','')
                emailText=emailText.replace('\n','').replace('\t','')
                if(len(mails)==0)or(emailText not in mails):
                    print(emailText)
                mails.append(emailText)
for link in allLinks:
    if(link.startswith("http") or link.startswith("www")):
        r=requests.get(link)
        data=r.text
        soup=BeautifulSoup(data,'html.parser')
        findMails(soup)

    else:
        newurl=url+link
        r=requests.get(newurl)
        data=r.text
        soup=BeautifulSoup(data,'html.parser')
        findMails(soup)

mails=set(mails)
if(len(mails)==0):
    print("NO MAILS FOUND")

哪里有错误？我昨天没有回答吗？
