Итерация по словарям JSON (Bing API)

Я пытаюсь извлечь все значения DisplayUrl из JSON, возвращаемые Bing API. Я не уверен, что я делаю неправильно. Любое понимание ценится!

search_response = urllib2.urlopen(request)
search_results = search_response.read()
results = json.loads(search_results)
for item in results.get(u'Web', []):
     print item.get(u'DisplayUrl')

Мой запрос настроен на возврат двух результатов, поэтому я хочу получить два отпечатка с ключа DisplayUrl.

Полученное results:

        u'results': [
