打印python嵌套字典中的int值&x27；int'；对象是不可编辑的

我试图访问一个嵌套的JSON文件，并通过将其导入python字典来打印其数据。当我把它们打印出来时，最后一个值有一个错误，它是字典中的int值

这是我的JSON数据

},

}

以下是我的python代码：

import json
with open('dataset/sample-checkin.json') as json_data:
    d = json.load(json_data)

for day in d["time"]:
    for time in d["time"][day]:
        for checkin in d["time"][day][time]:
            print(day, time, checkin)

---

错误：对于签入d[“time”][day][time]：TypeError:“int”对象不可编辑

最后一个循环没有意义。。。那边没什么可绕的。（正如错误所说，该值是一个

int

）我想您可能想要这样的值：

for day in d["time"]:
    for time in d["time"][day]:
        checkin = d["time"][day][time]
        print(day, time, checkin)
