python爬取网站图片：爬出来图片全部都不全且只能爬一张？

Question

## 爬取的时候只有一张，有时候特别慢，而且爬出来文件全部都不全，

图片是我爬了好几次的结果

上代码：

import requests
from urllib import request
from bs4 import BeautifulSoup
import re
import random
# url网址
st_url = "https://konachan.net/post"
# 设置headers
ua = [

# 设置beautiful soup标签并爬取

request.urlretrieve(url_,path+img_+".jpg")
print(img_+".jpg"+"下载完成!")

求教各位朋友救火。多谢！！

你这写的很让我迷茫啊，你用for遍历了储存图片的列表（for o in name:）但是，重点是你把请求图片的代码（request.urlretrieve(url_,path+img_+".jpg"))放在循环的外面，你这样操作_img的值就是列表的最后一项，所以只有一张图不是很正常的事吗？知道怎么改了吧
