Get path of all the elements in dictionary
我在python中有一个字典，想要获取值param1或param2的路径，…用其他值替换这些值。比如说，要获取param1的值，我需要像获取['optionsettings'][2]['value']一样获取它。我可以用一些通用代码来做这个吗？它将打印我所有节点/叶的路径下面是字典

这基本上是同一个问题：
为python嵌套字典的所有值打印完整的键路径
它本质上是必要的代码。您需要添加的是对列表的处理，因为您不只是提供一个键/值结构，可以通过以下问题来解决：
如何在python中检查变量是否为字典
它将向您展示如何检查类型并根据数据类型修改行为。实现这一点的最简单方法是设置两个虚拟数据类型，一个定义为空列表，另一个定义为空映射，并对虚拟类型的元素执行"isInstance"检查，以决定要执行的逻辑。
在这两个答案之间，您应该能够构建您正在寻找的路径。
迷路是对的，这不是一个"为我写"的网站。
这对我有用
