美丽的汤键错误'href'但绝对存在

Question

尝试从一个站点中提取所有链接。我得到了"；KeyError:'href'"但据我所知，这只适用于没有href的标签。然而，当我浏览汤对象时，每个a标记都有一个href。所以我不明白为什么我会看到这个错误。我查了很多，每个人都只提到一个没有href的标签。

from bs4 import BeautifulSoup
from datetime import datetime
import pandas as pd
import requests
page_count = 1
catalog_page = f"https://40kaudio.com/page/{str(page_count)}/?s"
while page_count < 4:
print(f"Begin Book Scrape from {catalog_page}")
# Soup opens the page.
open_page = requests.get(catalog_page)
# We create a soup object that has all the page stuff in it
soup = BeautifulSoup(open_page.content, "html.parser")
# We iterate through that soup object and pull out anything with a class of "title-post"
for link in soup.find_all('h2', "title-post"):
print(link['href'])
else:
print('By the Emperor!')

Answer 1

link中没有href标记。然而，在link中有一个a标签，而在a标签中有href属性。

<a href="https://40kaudio.com/justin-d-hill-cadia-stands-audiobook/" rel="bookmark">Justin D. Hill &#8211; Cadia Stands Audiobook</a>

for link in soup.find_all('h2', "title-post"):
print(link.a['href'])

不要忘记在while循环中增加page_count。
