我想从页面中抓取元素，例如页面 - https://www.aacr.org/?s=breast+cancer&search_type=global标题的 html 标签包含一个 html 链接和附加的标题。当我运行代码时，它会打印 HTML（第一个位置），然后打印标题（第二个位置/我想要的内容）例如 - 打印返回 -> <a href="https://www.aacr.org/ Patients-caregivers/cancer/breast-cancer/" title="Breast Cancer ">乳腺癌，我只想要粗体/第二个元素，有什么帮助吗？这是我的代码 -import requestsimport timefrom bs4 import BeautifulSoupimport pandas as pdproductlinks = []sam=[]for x in range(1,3): url=f'https://www.aacr.org/page/{x}/?s=breast+cancer&search_type=global' r=requests.get(url) soup=BeautifulSoup(r.content,'html.parser') productlist=soup.find_all('div',class_='blog-content') for item in productlist: title=soup.find_all('h3') print(title)

你必须再做一次迭代才能得到你想要的，通过迭代每个 a 标签（我保持你的代码完整并添加了额外的循环，这样你就可以看到一般如何做到这一点的具体细节，而不仅仅是对于这个特定的用例）。
import requests
import time
from bs4 import BeautifulSoup
import pandas as pd
productlinks = []
sam=[]
for x in range(1,3):
url=f'https://www.aacr.org/page/{x}/?s=breast+cancer&search_type=global'
r=requests.get(url)
soup=BeautifulSoup(r.content,'html.parser')
productlist=soup.find_all('div',class_='blog-content')
for item in productlist:
title=soup.find_all('h3')
for single in title:
print(single.a['title'])
结果：
Breast Cancer
Male Breast Cancer
Breast Cancer Prevention (PDQ®)
Breast Cancer Screening (PDQ®)

要获取该title属性，只需将最后一个更改for loop为：
for item in productlist:
a_tag =item.find('a')
print(a_tag['title'])
输出：
