从汤查找结果中提取href链接的问题

Question

我正在尝试从第一个搜索省份内的网站 https://www.lianjia.com/city/ 获取链接。从第一个省开始，我想获取属于该省的城市的链接，我找到了所有带有 href 链接的 li 标签 print(t)，但是当我尝试通过t.get('href')提取链接时，它什么也没返回，下面的代码有什么问题，有人可以帮忙吗？

url1 = 'https://www.lianjia.com/city/'
req1 = requests.get(url1)
soup1 = BeautifulSoup(req1.content, 'html.parser')
part = soup1.findAll("div",{"class":"city_province"})
for t in part[0].find_all('li'):
    print(t)
    print(t.get('href'))

Answer 1

li 标签没有href 属性。您必须获得所有锚点才能获得href。

试试这个：

import requests
from bs4 import BeautifulSoup

soup = BeautifulSoup(requests.get('https://www.lianjia.com/city/').content, 'html.parser')
provinces = soup.find_all("div", {"class": "city_province"})
anchors = [[a["href"] for a in p.find_all("a")] for p in provinces]

for province_urls in anchors:
    print(province_urls)

输出：

['https://aq.lianjia.com/', 'https://cz.fang.lianjia.com/', 'https://hf.lianjia.com/', 'https://mas.lianjia.com/', 'https://wuhu.lianjia.com/']
['https://bj.lianjia.com/']
['https://cq.lianjia.com/']
['https://fz.lianjia.com/', 'https://quanzhou.lianjia.com/', 'https://xm.lianjia.com/', 'https://zhangzhou.lianjia.com/']
and so on...
