python - token 化后如何提取 http 或 https？

Question

我有一个包含这样的文本的文本文件

>  because she s the worst 
    i am referring to  this   http  iimgurcom5srylmijpg  does it have any deeper meaning or does it signify anything  i just do nt get it why she d do that

    there are a shit ton of koutarous  but the presence of  one   https  smediacacheak0pinimgcomoriginals1219ed1219ed717fc2bfce372759bba2fe1cfegif  is enough to make it the most interesting party.

我通过首先将多个空格转换为单个空格来提取标记，因为使用命令空格不统一:

words = re.sub('\s+', ' ', sentence).strip()

现在，我只想获取 http 或 https，因为可以看出文本中没有正确的 URL。

我尝试使用 (http|https)\s 但没有成功。

还有其他替代方案吗？

使用以下正则表达式查找 http 或 https:http(s)?(\s+) 查看工作 regex .

要同时获取组中的 http 或 https，请使用 (http(s)?(\s+))，如下所示 regex .
