Recursive function to create hierarchical JSON object?

Question

I\'m just not a good enough computer scientist to figure this out by myself :(

I have an API that returns JSON responses that look like this:

// call to

You're not returning anything from each call to the recursive function. So, it seems like you just want to append each temp_obj dictionary into a list on each iteration of the loop, and return it after the end of the loop. Something like:

def get_child_nodes(node_id):   
    request = urllib2.Request(ROOT_URL + node_id)
    response = json.loads(urllib2.urlopen(request).read())
    nodes = []
    for childnode in response['childNode']:
        temp_obj = {}
        temp_obj['id'] = childnode['id']
        temp_obj['name'] = childnode['name']
        temp_obj['children'] = get_child_nodes(temp_obj['id'])
        nodes.append(temp_obj)
    return nodes

my_json_obj = json.dumps(get_child_nodes(ROOT_ID))

(BTW, please beware of mixing tabs and spaces as Python isn't very forgiving of that. Best to stick to just spaces.)
