请问如何数据放在leancloud里面如何查询？

我数据存在leancloud里面，要用python做个查询，比如我知道一个人员的名字，想查询他的年龄，我看了leancloud的官方文档的查询：

1：

 from leancloud import Object
from leancloud import

QueryGameScore = Object.extend('GameScore')query = Query(GameScore)

query.equal_to('playerName', 'Dan Stemkoski')
gameScores = query.first()
print gameScores

输出的是一个

 <leancloud.object_.GameScore object at 0xb75072cc>,

不知道如何读取这个数据的内容

2：然后我看有个select

 GameScore = Object.extend('GameScore')
query = Query(GameScore)
query.select('score', 'playerName')

仍然返回

 <leancloud.object_.GameScore object at 0xb75072cc>

3 然后试了一下fetch()，返回的是None，我确定表里是有数据的。

 GameScore = Object.extend('GameScore')
query = Query(GameScore)
query.select('score', 'playerName')
print query.first().fetch()

请问该如何写代码，能像select age from people where name = ‘Jim’一样返回一个字段信息？

from leancloud import Object
from leancloud import

QueryGameScore = Object.extend('GameScore')
query = Query(GameScore)

query.equal_to('playerName', 'Dan Stemkoski')
gameScores = query.first()
print gameScores.get('score')
