我在学习Python。我一直试图从Quandl中提取数据，我成功地加载了数据，但是当我尝试将其转换为Python时，它会抛出一个ValueError！

    ValueError                                Traceback (most recent call last)
 <ipython-input-10-0b58998505ee> in <module>()
----> 1 data=dict(data)
ValueError: dictionary update sequence element #0 has length 1; 2 is required

下面是我的代码，

import json,urllib2
url = "https://www.quandl.com/api/v3/datasets/NASDAQOMX/NQASIA0001LMGBPT.json"
loaded = urllib2.urlopen(url).read()
