打印python嵌套字典中的整数值，“int”对象不可迭代

Question

我尝试访问一个嵌套的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，字典中最后一个int值出现了一个错误。你知道吗

这是我的JSON数据

        "23:00": 2
    }
},

}

下面是我的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iterable

Answer 1

最后一个循环没有意义。。。那边没什么可绕的。（正如错误所说，这个值是int。）我想您可能希望这样：

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