How to get use index to get a value from unicode data type in python

Sorry for asking a repeating question, but I am stuck here. In my code, a variable contains the following data:

{  
"AlarmName":"ZDR ALARAM - 404 - ERROR",
"AlarmDescription":"This will check the 404 Errors in ZDR server",
"Trigger":{  
   "MetricName":"ZDR4dor",
   "Namespace":"ZDRLdics",
   "StatisticType":"Statistic",
   "Statistic":"SUM",
   "Unit":null,
   "Dimensions":[       ],
   "Period":60,
   "EvaluationPeriods":1,
   "ComparisonOperator":"GreatergrfdgsThreshold",
   "Threshold":0,
   "TreatMissingData":"",
   "EvaluatxcbleCountPercentile":""
}
}

I need to get AlarmName. I am using var['AlarmName'], but it shows the error index must be an integer not string. When I use var[0] it shows the output { only,

The object type is <type 'unicode'>

How do I get the exact value of the key 'AlarmName'?

Currently your var is just a (unicode) string containing the information. You need to parse it, so it is a dictionary object, which can handle the item access. The easiest way is to use the json module, since your string seems to be a valid json object:

import json

var = """
{  
"AlarmName":"ZDR ALARAM - 404 - ERROR",
"AlarmDescription":"This will check the 404 Errors in ZDR server",
"Trigger":{  
   "MetricName":"ZDR4dor",
   "Namespace":"ZDRLdics",
   "StatisticType":"Statistic",
   "Statistic":"SUM",
   "Unit":null,
   "Dimensions":[       ],
   "Period":60,
   "EvaluationPeriods":1,
   "ComparisonOperator":"GreatergrfdgsThreshold",
   "Threshold":0,
   "TreatMissingData":"",
   "EvaluatxcbleCountPercentile":""
}
}
"""

var = json.loads(var)
print(var['AlarmName'])
# ZDR ALARAM - 404 - ERROR
