How to read key value in JSON output without using index

Here is a sample JSON output myJSON:

{ "results": [
    {
      "data1": 123.45,
      "data2": 67.89
    }
  ]
}

I’m trying to directly read data1:

mydata1 = myJSON['data1']

I get an error KeyError: 'data1'. I can only find a way to do this by using an index:

mydata1 = myJSON['results'][0]['data1']

Is there a way to directly read the value in data1 without having to specify an index for results? Or is an index required? Just trying to find a more compact / elegant solution here.

>Solution :

Your json is :

myJSON = {

    "results": [
        {
          "data1": 123.45,
          "data2": 67.89
        }
      ]
}

If you want to get data1 without using index you can use for loop. this will take O(N) time:

for x in myJSON["results"]:
  mydata1 = x['data1']

print(mydata1)
#123.45

Or List comprehension:

mydata1 = [x['data1'] for x in myJSON["results"]]

print(*mydata1)
#123.45

Ideally,it should be with O(1) time

mydata1 = myJSON['results'][0]['data1']

Or

mydata1 = myJSON['results'][-1]['data1']
