您可以使用正则表达式或者BeautifulSoup库来提取a标签中的信息。

使用正则表达式：

import re

html = '<span class="comment-info"> <a class="" href="https://www.douban.com/people/duduxiongzhifu/">嘟嘟熊之父</a> <span>看过</span> <span class="allstar20 rating" title="较差"></span> <span class="comment-time" title="2023-06-02 14:46:24"> 2023-06-02 14:46:24 </span> <span class="comment-location">北京</span>'

pattern = r'<a.*?>(.*?)</a>'
result = re.findall(pattern, html)
print(result)

输出结果为：['嘟嘟熊之父']

使用BeautifulSoup库：

from bs4 import BeautifulSoup

html = '<span class="comment-info"> <a class="" href="https://www.douban.com/people/duduxiongzhifu/">嘟嘟熊之父</a> <span>看过</span> <span class="allstar20 rating" title="较差"></span> <span class="comment-time" title="2023-06-02 14:46:24"> 2023-06-02 14:46:24 </span> <span class="comment-location">北京</span>'

soup = BeautifulSoup(html, 'html.parser')
a_tag = soup.find('a')
print(a_tag.string)

输出结果为：嘟嘟熊之父
