Python 如何遍歷嵌套的 json 字典並僅打印選定的值

Question

從這個包含 10 個聲明的 JSON 字典中，我只想打印文本、標題、url 和 TextualRating。 由於嵌套字典，我有點困惑。

我如何遍歷所有這些並僅打印我們為它們選擇的參數（文本、標題、url 和 TextualRating）

Json 代碼：

'''{'claims': [{'text': 'Apple AirPods 會破壞你的健康，發出的輻射是頭戴式耳機的 5 倍，並且發出的輻射“比微波爐還多”', 'claimant': '社交媒體用戶', 'claimDate': '2022-05-01T00:00:00Z', 'claimReview': [{'publisher': {'name': 'USA Today', 'site': 'usatoday.com'}, '網址'：'https://www.usatoday.com/story/news/factcheck/2022/08/10/fact-check-context-missing-claim-health-effects-airpods/9661778002/'，'標題'： '事實核查：關於 AirPods 和其他藍牙耳機的健康影響的聲明缺少上下文'，'reviewDate'：'2022-08-11T01:33:14Z'，'textualRating'：'缺少上下文'，'languageCode'：'en '}]}, {'text': 'Apple Logo Alan Turing Death', 'claimant': 'facebook.com', 'claimDate': '2022-07-01T20:40:00Z', 'claimReview': [{ 'publisher': {'name': 'Lead Stories', 'site': 'leadstories.com'}, 'url': 'https://leadstories.com/hoax-alert/2022/07/fact-check-蘋果標志不是榮譽發明者艾倫圖靈誰可能已經死於中毒apple.html'，'標題' ：“事實核查：Apple 徽標不是為了紀念可能死於蘋果中毒的發明家 Alan Turing”、“reviewDate”：“2022-07-01T20:40:00Z”、“textualRating”：“Urban Legend”、“languageCode” : 'en'}]}, {'text': '來自 Apple AirPods 的輻射很危險', 'claimant': '社交媒體用戶', 'claimReview': [{'publisher': {'name': 'THIP Media' , '網站': 'thip.media'}, 'url': 'https://www.thip.media/health-news-fact-check/fact-check-is-radiation-from-apple-airpods-dangerous /30863/', 'title': 'Fact Check: 來自 Apple AirPods 的輻射危險嗎？', 'reviewDate': '2022-05-04T00:00:00Z', 'textualRating': 'Mostly False', 'languageCode' : 'en'}]}], 'nextPageToken': 'CAM'}'''

Answer 1

我希望你的 json 結構如下，

{'claims': [{
                       'text': 'Apple AirPods destroy your health, emit 5 times more radiation than over-ear headphones and emit "more radiation than a microwave"',
                       'claimant': 'Social media users', 'claimDate': '2022-05-01T00:00:00Z', 'claimReview': [
        {'publisher': {'name': 'USA Today', 'site': 'usatoday.com'},
         'url': 'https://www.usatoday.com/story/news/factcheck/2022/08/10/fact-check-context-missing-claim-health-effects-airpods/9661778002/',
         'title': 'Fact check: Claim about health effects of AirPods and other Bluetooth earphones is missing context',
         'reviewDate': '2022-08-11T01:33:14Z', 'textualRating': 'Missing Context', 'languageCode': 'en'}]},
                   {'text': 'Apple Logo Alan Turing Death', 'claimant': 'facebook.com',
                    'claimDate': '2022-07-01T20:40:00Z', 'claimReview': [
                       {'publisher': {'name': 'Lead Stories', 'site': 'leadstories.com'},
                        'url': 'https://leadstories.com/hoax-alert/2022/07/fact-check-apple-logo-is-not-honoring-inventor-alan-turing-who-may-have-died-by-poisoned-apple.html',
                        'title': 'Fact Check: Apple Logo Is NOT Honoring Inventor Alan Turing Who May Have Died By Poisoned Apple',
                        'reviewDate': '2022-07-01T20:40:00Z', 'textualRating': 'Urban Legend', 'languageCode': 'en'}]},
                   {'text': 'Radiation from Apple AirPods dangerous', 'claimant': 'Social media user', 'claimReview': [
                       {'publisher': {'name': 'THIP Media', 'site': 'thip.media'},
                        'url': 'https://www.thip.media/health-news-fact-check/fact-check-is-radiation-from-apple-airpods-dangerous/30863/',
                        'title': 'Fact Check: Is radiation from Apple AirPods dangerous?',
                        'reviewDate': '2022-05-04T00:00:00Z', 'textualRating': 'Mostly False', 'languageCode': 'en'}]}],
        'nextPageToken': 'CAM'}

在這種情況下，您可以使用以下代碼從鍵中提取值，

claims_json_data = {'claims': [{
                       'text': 'Apple AirPods destroy your health, emit 5 times more radiation than over-ear headphones and emit "more radiation than a microwave"',
                       'claimant': 'Social media users', 'claimDate': '2022-05-01T00:00:00Z', 'claimReview': [
        {'publisher': {'name': 'USA Today', 'site': 'usatoday.com'},
         'url': 'https://www.usatoday.com/story/news/factcheck/2022/08/10/fact-check-context-missing-claim-health-effects-airpods/9661778002/',
         'title': 'Fact check: Claim about health effects of AirPods and other Bluetooth earphones is missing context',
         'reviewDate': '2022-08-11T01:33:14Z', 'textualRating': 'Missing Context', 'languageCode': 'en'}]},
                   {'text': 'Apple Logo Alan Turing Death', 'claimant': 'facebook.com',
                    'claimDate': '2022-07-01T20:40:00Z', 'claimReview': [
                       {'publisher': {'name': 'Lead Stories', 'site': 'leadstories.com'},
                        'url': 'https://leadstories.com/hoax-alert/2022/07/fact-check-apple-logo-is-not-honoring-inventor-alan-turing-who-may-have-died-by-poisoned-apple.html',
                        'title': 'Fact Check: Apple Logo Is NOT Honoring Inventor Alan Turing Who May Have Died By Poisoned Apple',
                        'reviewDate': '2022-07-01T20:40:00Z', 'textualRating': 'Urban Legend', 'languageCode': 'en'}]},
                   {'text': 'Radiation from Apple AirPods dangerous', 'claimant': 'Social media user', 'claimReview': [
                       {'publisher': {'name': 'THIP Media', 'site': 'thip.media'},
                        'url': 'https://www.thip.media/health-news-fact-check/fact-check-is-radiation-from-apple-airpods-dangerous/30863/',
                        'title': 'Fact Check: Is radiation from Apple AirPods dangerous?',
                        'reviewDate': '2022-05-04T00:00:00Z', 'textualRating': 'Mostly False', 'languageCode': 'en'}]}],
        'nextPageToken': 'CAM'}

for claim in claims_json_data['claims']:
    print(f"text: {claim['text']}")
    for review in claim['claimReview']:
        print(f"url: {review['url']}")
        print(f"title: {review['title']}")
        print(f"textualRating {review['textualRating']}")
        print('\n')
