你可以请求一些JSON数据并进行解析。下面的代码会给你返回第一个（最新的）结果，并把它存储在first这个变量里。
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']
我刚在一个交互式的Python环境中查看了这个JSON对象。你可以自己构建查询，或者使用我发的那个。记得要更改作者的信息。这是一种比较底层的方法，而@Frederik提到了一种更高层次的做法。
这个first对象看起来是这样的。
