大一爬虫题~想问问怎么写

上课的爬虫题！添加完了ueragent，还是显示不出来内容。也没有报错，是哪里还有问题嘛！！谢谢~~

你如果代码不截图，直接发源码，这边还可以调试看看

import requests
import json
from lxml import etree

response = requests.get(url,headers=header)
content = response.content.decode()
html = etree.HTML(content)
res = html.xpath("//a[@class='cfix job-hover-color']")
List = []
for i in res:
    j={}
    j["place"]=i.xpath("./span[@class='fl']/text()")[1].strip()
    x=i.xpath("./span[@class='fr']/text()")[0].split(",")[0].split("K")[0]
    if'.' in x:
        #y=print(int(float(x)*1000))
        j["date"] = int(float(x)*1000)
    else:
        j["date"] = x
        print(j)
        List.append(j)
print(List)
with open("02.json","w",encoding="utf-8") as f:
    json.dump(List,f,ensure_ascii=False,indent=2)
print("success!")
