Check if key in json has another keys within in Python : Im trying to print my json content. I know how to print just keys and values but I want to have access to the objects within the keys too. This is my code:

    json_mini = json.loads('{"one" : {"testing" : 39, "this": 17}, "two" : "2", "three" : "3"}')
        for index, value in json_mini.items():
            print index, value
            if value.items():
                for ind2, val2 in value.items():
                    print ind2, val2

which gives me this error: `AttributeError: 'unicode' object has no attribute 'items'`

How to iterate over it? So I can do some process on each separate key and value?
