我有一个下面显示的字典,我想用新值更新“时间”键(嵌套字典的两个键)。
{
"mReport": {
"reports": 1,
"time": "2017-08-04T16:33:19",
"m_reports": [{
"name": "eth0",
"int": "eth0",
"type": "data",
"datatype": "STRING",
"value": 0,
"unit": "",
"time": "2017-08-04T16:33:19"
}]
}
}
我尝试了这个,但是我能够更新外部时间键(在mReport下),m_reports下的键根本不可访问。 我的代码,仅适用于外键:
for _, dv1 in kpi_resp.iteritems():
for key1, dv2 in dv1.iteritems():
if key1 == 'time':
dv1["time"] = "2017-08-04T16:33:19"
需要帮助。

如果你直接这样做会怎么样:
new_value = "2017-08-04T16:33:19"
kpi_resp["mReport"]["time"] = new_value
kpi_resp["mReport"]["m_reports"][0]["time"] = new_value
或者,如果您需要为所有嵌套词典执行此操作:
new_value = "2017-08-04T16:33:19"
kpi_resp["mReport"]["time"] = new_value
for report in kpi_resp["mReport"]["m_reports"]:
report["time"] = new_value
