我有一个熊猫数据框，如下例所示。列0具有许多html标记，在尊重行顺序的同时，我需要从中提取所有URL并将它们添加为此DataFrame中的列。
在这种情况下，第2列第0行将具有：“https://sco...”。实际上，此列最多可以包含10个URL，应将其添加到数据框的各个列中。我曾尝试使用Beautiful Soup，但无法使它与像这样的Dataframe一起正常工作。
我尝试使用下面的正则表达式提取所有这些URL，但无法将其插入数据框。
postsOnlyURL = re.findall('"(http.*?)"',all_text,re.IGNORECASE|re.DOTALL)
0 1
0 src="https://sco ... publicado a 23/10/2019Ident...
1 Ativo</div></div><div class="_7jwu">Começou a ... AtivoComeçou a ser publicado a 23/10/2019Ident...
2 Ativo</div></div><div class="_7jwu">Começou a ... AtivoComeçou a ser publicado a 23/10/2019Ident...
有没有办法使这项工作有效？
答案
import pandas as pd
import re
from bs4 import BeautifulSoup
