如何在减去2个大熊猫日期的同时获得天数差异

Question

我正在尝试在python中减去2个日期。目前，我将输出作为datetime。我只是想几天而已。

我的代码

{
    "_id" : 123,
    "vendor" : "ut",
    "boxes" : [ 
        {
            "boxRef" : 321,
            "items" : [ 
                {
                    "Tag" : "dolore",

                }, 
                {
                    "Tag" : "irure",

                }, 
                {
                    "Tag" : "labore",

                }
            ]
        }, 
        {
            "boxRef" : 789,
            "items" : [ 
                {
                    "Tag" : "incididunt",

                }, 
                {
                    "Tag" : "magna",

                }, 
                {
                    "Tag" : "laboris",

                }
            ]
        }, 
        {
            "boxRef" : 456,
            "items" : [ 
                {
                    "Tag" : "reprehenderit",

                }, 
                {
                    "Tag" : "reprehenderit",

                }, 
                {
                    "Tag" : "enim",

                }
            ]
        }
    ]
}

当前输出

data['Delay_Days'] = ((pd.to_datetime(data['Actual Delivery date/time']) - 
                            pd.to_datetime(data['Planned Delivery date/time'])))

预期产量

1          0 days 06:53:00
2        -1 days +06:53:00
3          0 days 03:06:00
4          0 days 03:06:00
5          0 days 03:27:00
6          0 days 03:27:00
7          0 days 03:27:00
8          0 days 03:27:00
9          0 days 11:52:00
10         0 days 13:00:00

这怎么办？
