如何在Python中从站点获取随机图像链接？

Question

我对网络抓取还不熟悉，但我对它了解不多。我已经做了一个程序，从一个网站获取一个随机图像链接，但我得到了一个链接列表，而这样做，我没有得到一个链接

这是我的密码

from bs4 import BeautifulSoup
import urllib.parse
from urllib.request import urlopen,Request
import random


requester = {'User-Agent': 'Mozilla/5.0'}
req=Request("https://image.com",headers=requester)
u =urlopen(req)


soup = BeautifulSoup(u.read(), features="lxml")



links = soup.find_all('a')

images =[]
for img in soup.findAll('img'):
    images.append(img.get('src'))
    img=random.choice(images)
    
    print(img)

这是输出

我只想从上面的列表中的一个链接也链接应随机

Answer 1

在for循环外使用img=random.choice(images)

images =[]
for img in soup.findAll('img'):
    images.append(img.get('src'))

img=random.choice(images)    
print(img)
