就是想爬取整个排行榜的壁纸的图片，然后存到一个文件夹里面。

楼主，我把你的代码改了一下，这样就行了。

import requests
from lxml import etree
import os
import re

from torch import mode

url = 'https://wallhaven.cc/toplist?'
headers = {
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/96.0.4664.110 Safari/537.36 Edg/96.0.1054.62'
}
response = requests.get(url=url, headers=headers)
page_text = response.text
tree = etree.HTML(page_text)
as_href = tree.xpath('//*[@id="thumbs"]/section[1]/ul/li//a/@href')
if not os.path.exists('./壁纸'):
    os.mkdir('./壁纸')
for a_href in as_href:
    rsp = requests.get(url=a_href,headers=headers)
    html2 = etree.HTML(rsp.text)
    img_src = html2.xpath("//img[@id='wallpaper']/@src")[0]
    img_name = re.findall('.*-(.*)',img_src)[0]
    content2 = requests.get(url= img_src,headers=headers).content
    with open(file='./壁纸/{}'.format(img_name),mode='wb') as f:
        f.write(content2)

这个网站上的图片是真的不错呀！感谢楼主的分享！
