如下所示：

from bs4 import BeautifulSouppath = './web/new_index.html'with open(path, 'r') as f: Soup = BeautifulSoup(f.read(), 'lxml') titles = Soup.select('ul > li > div.article-info > h3 > a')for title in titles: print(title.text)输出：Sardinia's top 10 beachesHow to get tannedHow to be an Aussie beach bumSummer's cheat sheet

#其中titles = Soup.select('ul > li > div.article-info > h3 > a')#等效titles = Soup.select('h3 a')

print(title.text)#等效print(title.get_text())print(title.string)

也可以使用以下代码

import bs4  path = './web/new_index.html'  with open(path, 'r') as f:  Soup = bs4.BeautifulSoup(f.read(), 'lxml')   titles = Soup.select('h3 a') for title in titles:  print(title.string)

Html原文：
