如何使用Python从另一个JSON对象创建新的JSON对象?
我需要创建一个JSON对象,它的信息比原始对象少: 从api服务获取原始JSON对象后,它看起来如下所示:如何使用Python从另一个JSON对象创建新的JSON对象?,python,json,cisco,Python,Json,Cisco,我需要创建一个JSON对象,它的信息比原始对象少: 从api服务获取原始JSON对象后,它看起来如下所示: { "queryResponse": { "@type": "AccessPointDetails", "@rootUrl": "https://xxx/webacs/api/v1/data", "@requestUrl": "https://xxx/webacs/api/v1/data/AccessPointDetails?.full=true&.fi

如果查看,实体列表位于原始数据的字典中
我试图找到关于此的信息,但我只找到了如何删除或如何每次提取1个数据的信息
如何在Python中实现这一点
问候
编辑:一篇重复的文章?如果是这样的话,请不要标记它,你能链接到答案吗,因为我花了几个小时寻找答案?(不适用于袁吉,谢谢你指出单独的资源)这很简单
完成你的问题只是和的组合 通过使用这两个问题的解决方案,您可以实现以下目标: 假设
s
是从json数据转换而来的dict
keys = ['@id', 'name', 'clientCount', 'clientCount_2_4GHz', 'clientCount_5GHz']
new_dict = {'entity': [{key: d['accessPointDetailsDTO'][key] for key in keys} for d in s['queryResponse']['entity']]}
然后使用以下方法转换new\u dict
:
与任何“如何将文件转换为文件”一样,将第一个文件加载到合理的对象结构中,然后按您认为合适的方式将其序列化为新格式。不要试图直接将文件结构转换为文本。与任何Python一样,“我有json对象”问题:Python中没有“json对象”这样的东西-json是一种文本格式,它转换为本机数据类型(dicts、list等)。谢谢,我只使用for语句,每个条目都有一行,但您的解决方案更高效。
