Question

我正在尝试使用webscraper和python对我的第一个BeautifulSoup进行编码。

我正在尝试检索网页上所有列表的所有URL，但是我没有获得包含所有URL的数组，而是仅获得一个URL。

以下是我使用的代码

from urllib.request import urlopen as uReq
from bs4 import BeautifulSoup as soup

my_url = 'https://www.pararius.com/apartments/enschede'

uClient = uReq(my_url)
page_html=uClient.read()
uClient.close()

page_soup = soup(page_html,"html.parser")

compartments = page_soup.findAll("li",{"class":"property-list-item-container"})

#Here is where im trying to store all the urls in url_det 
for compartment in compartments:
    url_det = compartment.h2.a["href"]

感谢任何输入！

Answer 1

循环的每次迭代都将覆盖url_det的内容，而是使用列表推导将所有值存储在列表中，例如：

from urllib.request import urlopen as uReq
from bs4 import BeautifulSoup as soup

my_url = 'https://www.pararius.com/apartments/enschede'

uClient = uReq(my_url)
page_html=uClient.read()
uClient.close()

page_soup = soup(page_html,"html.parser")

compartments = page_soup.findAll("li",{"class":"property-list-item-container"})

url_det = [compartment.h2.a["href"] for compartment in compartments]

print(url_det)
>>> ['/house-for-rent/enschede/PR0001596564/otto-van-taverenstraat', ... , '/house-for-rent/enschede/PR0001594320/hanenberglanden']

Python for循环未遍历所有元素
