                }
            ]
        }
    }
}

我上面有 JSON，需要用这样的输出来解析它

Logging__LogLevel__Default
Authentication__ApiKeys__0__Claims__0__Type

我在python3中有这个代码：

def checkdepth(sub_key, variable):
    delmt = '__'
    for item in sub_key:
        try:
            if isinstance(sub_key[item], dict):
                sub_variable = variable + delmt + item
                checkdepth(sub_key[item], sub_variable)
        except TypeError:
            continue

        if isinstance(sub_key[item], list):
            sub_variable = variable + delmt + item
            for it in sub_key[item]:
                sub_variable = variable + delmt + item + delmt + str(sub_key[item].index(it))
                checkdepth(it, sub_variable)
            print(sub_variable)

        if isinstance(sub_key[item], int) or isinstance(sub_key[item], str):
                sub_variable = variable + delmt + item
                print (sub_variable)

for key in data:   
    if type(data[key]) is str:
       print(key + '=' +str(data[key]))
    else:
      variable = key
      checkdepth(data[key], variable)

一切正常，但我总是在这个输出中得到一些字符串

Authentication__ApiKeys__0__Key
Authentication__ApiKeys__0__OwnerName
Authentication__ApiKeys__0__Claims__0__Type
Authentication__ApiKeys__0__Claims__0__Value
Authentication__ApiKeys__0__Claims__0
Authentication__ApiKeys__2
Authorization__Permissions__Roles__0__Role
Authorization__Permissions__Roles__0__Permissions__1
Authorization__Permissions__Roles__1__Role
Authorization__Permissions__Roles__1__Permissions__0
Authorization__Permissions__Roles__1

为什么我的代码添加的不是完整的字符串

Authentication__ApiKeys__0__Claims__0
Authentication__ApiKeys__2
Authorization__Permissions__Roles__1

为什么它不打印来自

的每个值

Authorization__Permissions__Roles__0__Permissions__*

来自

Authorization__Permissions__Roles__1__Permissions__*

我知道我处理列表数据类型的块中的问题
