在Python和Beautifutsoup中，如何获得URL链接，而不是从汤中获得HREF？

Question

使用以下代码：

prop_img = prop_lst.find_all('a',{'class':'mpi_img_link'})

我将获得以下输出的列表：

[<a class="mpi_img_link" href="/homedetail/5324-palm-royale-blvd-sugar-land-tx-77479/2504873" style="background-image:url(https://photos.harstatic.com/205383563/lr/img-1.jpeg?ts=2022-03-02T17:03:25.300);"></a>,

我认为您应该在下面使用CSS选择器，但是我仍然无法实现最终目标。谁能帮忙吗？谢谢你！

for img in prop_img:
    print(prop_lst.select('style'))

Answer 1

几乎在那里。尝试：

for img in prop_img:
    print(img['style'])

拔出URL部分：

import re

for img in prop_img:
    url = re.search('\((.*)\)', img['style']).group(1)  
    print(url)
