Python-访问JSON中的字段

我在访问JSON API中获得的某些字段时遇到问题，在API中，如果用户是多个on_调用策略的一部分，我不知道如何访问第二个或多个策略。我当前的代码只是在网络团队策略下返回Bob Brown两次，而不是在网络团队和solarwinds测试下返回Bob Brown两次

JSON示例

请包括您的异常/错误打印迭代中的值，我认为您正在以相同的方式覆盖object@JanvanderVegt这可能是正确的，因为您在开始循环

用户项目数据['on\u call']

用户项目数据。你应该在每次迭代中创建一个新的，以防止出现这种情况。我认为这已经做到了！请包括您的异常/错误打印迭代中的值，我认为您正在以相同的方式覆盖object@JanvanderVegt这可能是正确的，因为您在开始循环
