format dictionary using python - python-2.7

Question

I am new to python, can someone tell me how can we change the given code into the formatted code given below .
The data is stored in a dictionary and i want to store the formatted data also in a dictionary.
I am using python version 2.7.
Is it possible to do the same?
Can the alterations be made in the same dictionary or we need to create a new dictionary?
The code I have :
{
"roles":
{
"AA":[
{
"date":"20150101",
"total":6.0
},
{
"date":"20150201",
"total":14.5
},
{
"date":"20150301",
"total":14.5
}
],
"AB":[
{
"date":"20150301",
"total":1.6
},
{
"date":"20150401",
"total":1.6
},
{
"date":"20150501",
"total":7.24
}
]
}
}
The code I want :
{
"key" : "roles",
"values" : [
{
"key": "AA",
"values": [
{
"date": "20150101",
"total": 6
},
{
"date": "20150201",
"total": 14.5
},
{
"date": "20150301",
"total": 14.5
}
]
},
{
"key": "AB",
"values": [
{
"date": "20150301",
"total": 1.6
},
{
"date": "20150401",
"total": 1.6
},
{
"date": "20150501",
"total": 7.24
}
]
}
]
}

Answer 1

Not necessarily the most robust but gets the job done as long as the input format stays consistent with the example you provided (using pprint only for formatted output. You don't have to install it for the code to work)
from pprint import pprint
output = {}
for key, value in input_dict.items():
output['key'] = key
output['values'] = [{'key': inner_key, 'values': inner_value}
for inner_key, inner_value in value.items()]
pprint(output)
Outputs
{'key': 'roles',
'values': [{'key': 'AA',
'values': [{'date': '20150101', 'total': 6.0},
{'date': '20150201', 'total': 14.5},
{'date': '20150301', 'total': 14.5}]},
{'key': 'AB',
'values': [{'date': '20150301', 'total': 1.6},
{'date': '20150401', 'total': 1.6},
{'date': '20150501', 'total': 7.24}]}]}
