从python嵌套字典打印int值，'int'对象不可迭代答案

【问题标题】：print int value from python nested dictionary, 'int' object is not iterable从python嵌套字典打印int值，'int'对象不可迭代

【问题描述】：

我尝试访问嵌套的 JSON 文件并通过将其导入 python 字典来打印其数据。当我将它们打印出来时，最后一个值出现错误，它是字典中的 int 值。

这是我的 JSON 数据

},

}

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：签入 d["time"][day][time]: TypeError: 'int' object is not iterable

【解决方案1】：

最后一个循环没有意义......那里没有什么可以循环的。（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)
