python - YouTube的Python平均评分

Question

如何使用Python YouTube GData API调用gd:rating XML文件？

我将YouTube video_id作为变量，并且我知道可以返回以下内容:

<gd:rating average='4.553648' max='5' min='1' numRaters='233' rel='http://schemas.google.com/g/2005#overall'/>

我只是不知道如何在Python中做到这一点。

在previous question中，您已经演示了使用video_id检索条目的代码。

运行python:

>>> from gdata.youtube.service import YouTubeService
>>> yt = YouTubeService()
>>> entry = yt.GetYouTubeVideoEntry(video_id='pP9VjGmmhfo')
>>> entry.rating
<gdata.youtube.Rating object at 0x2722cd0>
>>> print entry.rating
<?xml version='1.0' encoding='UTF-8'?>
<ns0:rating average="4.4662576" max="5" min="1" numRaters="652" rel="http://schemas.google.com/g/2005#overall" xmlns:ns0="http://schemas.google.com/g/2005" />
>>> entry.rating.average
'4.4662576'
>>> entry.rating.numRaters
Traceback (most recent call last):
