Python键值错误（Json）

Question

我正在尝试获取此数据并打印为文本字符串，我遇到的效果最糟！使它工作的问题。这是我正在与之合作以更好地了解我正在开发环境控制器并且我的sonoff开关结合使用的源 https://github.com/FirstCypress/LiV/blob/master/software/liv/iotConnectors/sonoff/sonoff .py 一旦完成，此代码可用于两页，因此请忽略温度键等    m = json.loads(content)     co2  = m["Value"]我需要“ TaskValues”下的“ Value”的值在几乎任何情况下都应该为1或0，我将如何以正确的形式提取该键？"Sensors":[{"TaskValues": [{"ValueNumber":1,"Name":"Switch","NrDecimals":0,"Value":0}],"DataAcquisition": [{"Controller":1,"IDX":0,"Enabled":"false"},{"Controller":2,"IDX":0,"Enabled":"false"},{"Controller":3,"IDX":0,"Enabled":"false"}],"TaskInterval":0,"Type":"Switch input - Switch","TaskName":"relias","TaskEnabled":"true","TaskNumber":1}],"TTL":60000}

Answer 1

"Value"如前所述，嵌套在您的json中。要获得所需的内容，您需要遍历父数据结构：

m = json.loads(content)

# This is a list

a = m.get('Sensors')

# This is a dictionary

sensor = a[0]

# This is a list

taskvalue = sensor.get('TaskValues')

# Your answer

value = taskvalue[0].get('Value')
