YouTube平均評分於Python

Question

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

我在YouTube VIDEO_ID作爲一個變量，我知道這是可能返回此：

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

我只是無法弄清楚如何做到這一點在Python。

在您的previous question中，您已經演示了檢索給定條目video_id的代碼。

運行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):

AttributeError: 'Rating' object has no attribute 'numRaters' 
>>> dir(entry.rating)
