<p>I tried this way, but still remain some dicts inside sub-lists</p>

<pre><code>import urllib2
import json

response = urllib2.urlopen('http://www.site.com.br/produto/sku/5293')
data = json.load(response)

for a in data:
    for key, value in a.items():
        print key, value
</code></pre>

<p>This is the result, but as you guys can see, still remain some key-value inside the sub-list</p>
