Python如何遍历嵌套的json字典并只打印选定的值
在这个包含10个JSON的字典中，我只想打印文本、标题、url和TextualRating。我有点困惑，因为嵌套的字典。
我如何循环所有这些，并只打印选定的参数我们为他们全部(文本，标题，url和TextualRating)

Json代码：
{“声明”：“苹果AirPods破坏你的健康，发射的辐射是耳机的5倍，辐射比微波炉多”，“索赔人”：“社交媒体用户”，“声明日期”：‘2022-05-01T00:00:00:00Z’，‘评论’：{'publisher'：{'name'：‘美国之今’，'usatoday.com'} }，‘'url'：'https://www.usatoday.com/story/news/factcheck/2022/08/10/fact-check-context-missing-claim-health-effects-airpods/9661778002/'，'title'：’事实检查:声称AirPods和其他蓝牙耳机的健康影响‘，'reviewDate'：'2022-08-11T01:33:14Z'，’文本分析‘：’缺失上下文‘，’语言代码‘：'en'}}，{'text'：’‘，“索赔人”：“脸book.com”，“声明”：“2022-07-01T20:40:00Z”，“声明评论”：{“出版商”：{“名称”：“铅故事”，“站点”：“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'，“标题”：“事实查证:苹果Logo没有表彰可能死于苹果中毒的发明者艾伦图灵”、“评论日期”：“2022-07-01T20:40:00Z”、“文本分析”：“城市传说”、“语言代码”：“en”}、{“文本”：“来自苹果AirPods危险的辐射”、“申索人”：“社交媒体用户”、“声明评论”：{ {'publisher'：{'name'：‘thip.media’、‘thip.media’}、'thip.media'}，‘'url'：'https://www.thip.media/health-news-fact-check/fact-check-is-radiation-from-apple-airpods-dangerous/30863/'，'title'：’事实检查:来自苹果AirPods的辐射危险吗？‘、'reviewDate'：’2022-0504T00:00:00Z‘、’大部分错误‘、’语言代码‘：’en‘}}、'nextPageToken'：’CAM‘}’‘。

我希望你的json结构如下，
{'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'}在这种情况下，您可以使用以下代码提取值的形式键，
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': [

'reviewDate': '2022-05-04T00:00:00Z', 'textualRating': 'Mostly False', 'languageCode': 'en'}]}],
'nextPageToken': 'CAM'}
