在下面的python3代码中，我读取了json中的所有objects，然后在json中循环elements。如果我只搜索id is not None，则该元素和空值将被删除。但是，当我添加or语句以删除id is not ""时，打印整个文件时，或语句中的id都没有删除。作为python的新手，我不确定我做错了什么。谢谢：）。

文件

{
"objects": [
    {
        "version": "1",
        "list": [
            {
                "
                    "json": null
                },
                "id": "",
            }
        ],
        "h": "na"
    },
{
        "version": "1",
        "list": [
            {
                "
                    "json": null
                },
                "id": "This has text in it and should be printed",
            }
        ],
        "h": "na"
    },
{
        "version": "1",
        "list": [
            {
                "
                    "json": null
                },
                "id": null,
            }
        ],
        "h": "na"
    }
]
}

需要

{
        "version": "1",
        "list": [
            {
                "
                    "json": null
                },
                "id": "This has text in it and should be printed",
            }
        ],
        "h": "na"
    },

Python3

if v["id"] is not None or v['id'] is not "":

还尝试了以下操作，并更改了id：

for obj in data['objects']:
if obj.get('id') is "":
    obj['description'] = 'na'
