推荐答案
您可以请求 JSON 并解析它.以下代码为您提供第一个(最近的)结果并将其存储在 first 中.
You can request JSON and parse it. The following code gives you the first (most recent) result and stores it in first.
import urllib, json
author = 'Google'
inp = urllib.urlopen(r'http://gdata.youtube.com/feeds/api/videos?max-results=1&alt=json&orderby=published&author=' + author)
resp = json.load(inp)
inp.close()
first = resp['feed']['entry'][0]
# Title of the video
print first['title']
# URL
print first['link'][0]['href']
我只是在交互式 Python shell 中查看了 JSON 对象.您可以构建您自己的查询或使用我发布的查询.记得换作者.这是一种较低级别的方法，@Frederik 提到了一些更高级别的内容.
I just looked through the JSON object in an interactive Python shell. You can build your own query or use the one I posted. Remember to change the author. This is a lower level approach, and @Frederik mentioned something a bit higher level.
first 对象看起来像这样.
