Question

我试图访问嵌套的JSON文件并通过将它们导入python字典来打印它的数据。当我打印出来时，最后一个值的错误是字典中的int值。

这是我的JSON数据

{

        "1:00": 1,

    },
    "Saturday": {

    },
    "Monday": {
        "12:00": 1,
        "11:00": 1,
        "14:00": 1,
        "18:00": 1,
        "19:00": 1,
        "23:00": 1,
        "20:00": 1
    },
    "Tuesday": {
        "18:00": 2,
        "12:00": 1,
        "13:00": 2,
        "16:00": 1,
        "15:00": 1,
        "4:00": 1,
        "21:00": 1,
        "20:00": 2,
        "23:00": 2
    }
},
"business_id": "7KPBkxAOEtb3QeIL9PEErg"

}

这是我的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：在d [＆＃34; time＆＃34;] [day] [time]中签入：TypeError：＆＃39; int＆＃39;对象不可迭代

Answer 1

最后一个循环没有意义......那里没有什么可循环的。（正如错误所说，值是int。）我想你可能想要这样的东西：

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

从python嵌套字典中打印int值，＆＃39; int＆＃39;对象不可迭代
