python网络爬虫，运行报错

初学网络爬虫，运行报错，修改几次都不行，总是报错。
代码如下：

• 主要问题是网址得证书有问题，要增加veryfy=False不验证
• fillUnivlist最后return对齐有问题，对齐到for，要不只会循环一次
• printUnivList传递的参数有问题，只有31条，应该用len来获取数组实际数量
  

  

改成下面就可以了

import requests
from bs4 import BeautifulSoup
import bs4
import csv

import urllib3
urllib3.disable_warnings()##不试试ssl警告

def getHTMLText(url):
    try:
        r=requests.get(url,timeout=30,verify=False)###网址ssl证书有问题，要禁用证书验证，要不报错
        r.raise_for_status()
        r.encoding=r.apparent_encoding
        return r.text
    except:
        print('getHTMLText Error')
        return ''

def fillUnivlist(ulist,html):
    soup=BeautifulSoup(html,'html.parser')
    for tr in soup.find('tbody').children:
        if isinstance(tr,bs4.element.Tag):
            tds=tr('td')
            ulist.append([tds[0].string,tds[1].string,tds[2].string,tds[3].string,tds[4].string,tds[5].string])
    return ulist
def printUnivList(ulinst,num):
    tplt="{0:8}\t{1:^8}\t{2:^8}\t{3:^8}\t{4:^8}\t{5:^8}"
    for i in range(num):
        try:
            u=ulinst[i]
            print(tplt.format(u[0],u[1],u[2],u[3],u[4],u[5]))

        except:
            print('printUnivList Error')
            pass
def writeUlistfile(ulist):
    with open('ulist1.csv','w',newline='') as fout:
        writer=csv.writer(fout)
        for row in ulist:
            writer.writerow(row)
def main():
    uinfo=[]
    url='https://www.chyxx.com/industry/202103/938485.html'
    html=getHTMLText(url)
    ulist=fillUnivlist(uinfo,html)
    printUnivList(ulist,len(ulist))####

if __name__=='__main__':
    main()
