如何提取字符串的一部分，从一个词到另一个词？

Question

当我运行下面的代码得到一个很大的 JSON 响应时，我如何才能只提取视频的 URL？

from youtubesearchpython import VideosSearch

title = 'Video Name'
videosSearch = VideosSearch(title, limit = 0)
print(videosSearch.result())

Resul:

{
   "result":[
      {
         "type":"video",
         "id":"JJTqk8P9VO0",
         "title":"Kinemaster | how to create name intro || video editing tutorial",

         "duration":"9:02",
         "viewCount":{

            "short":"3.1M views"
         },
         "thumbnails":[

我是 Python 的新手，如有任何帮助，我们将不胜感激。

Answer 1

videosSearch.result() 只是一个字典，所以你可以像这样得到所有 url：

print([result["link"] for result in videosSearch.result()["result"]])

Answer 2

videosSearch.result()["result"][0]["link"]应该就是你要找的。

Answer 3

from youtubesearchpython import VideosSearch

title = 'Video Name'
videosSearch = VideosSearch(title, limit = 0)

response = videosSearch.result()

print([data["link"] for data in response["result"])
