Answer 1

.find()将返回它找到的第一个匹配的标记，而.find_all()将返回所有匹配的列表。

import requests
from bs4 import BeautifulSoup
url = 'https://www.mindtools.com/pages/main/newMN_CDV.htm'
response = requests.get(url)
soup = BeautifulSoup(response.text, 'html.parser')

ultag = soup.find('ul', {'class': 'collection test_further_resource'})
for litag in ultag.find_all('li'):
print(litag.find("a")["href"])

输出：
