我写运行报错

import requests
from bs4 import BeautifulSoup

headers={" User-Agent":" user-agent: Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/84.0.4147.89 Safari/537.36 SLBrowser/7.0.0.5211 SLBChan/27"}
for i in range(0,4):
    page=i*30
    url="http://www.zuihaodaxue.cn/zuihaodaxuepaiming2016.html" 
    response=requests.get(url,headers=headers)
    html=response.text
    soup=BeautifulSoup(html,"lxml")
    content_all=soup.find_all(class_="title")
    for content in content_all:
        contentString=content.string
        print(contentString)

 

Answer 1

是由于你user-agent中带了非必要的空格造成的。
