Get keys from json in python

Question

I have an API whose response is json like this:

{
"a":1,
"b":2,
"c":[
     {
     "d":4,
     "e":5,
     "f":{
         "g":6
         }
     }
    ]
}

How can I write a python program which will give me the keys ['d','e','g']. What I tried is:

jsonData = request.json() #request is having all the response which i got from api
c = jsonData['c']
for i in c.keys():
    key = key + str(i)
print(key)

Solution

Function which return only keys which aren't containing dictionary as their value.

jsonData = {
    "a": 1,
    "b": 2,
    "c": [{
        "d": 4,
        "e": 5,
        "f": {
            "g": 6
        }
    }]
}


def get_simple_keys(data):
    result = []
    for key in data.keys():
        if type(data[key]) != dict:
            result.append(key)
        else:
            result += get_simple_keys(data[key])
    return result

print get_simple_keys(jsonData['c'][0])

To avoid using recursion change line result += get_simple_keys(data[key])to result += data[key].keys()

Thanks andriy.. It gave me ['e', 'd', 'f']. i want 'g' rather than 'f'. I think i need one more loop inside it.

[Andriy Ivaneyko]

yes but it wouldn't be best way ... need solution without recursion ?

[Sagar]

yes please that would be very helpful. Thanks again @Andriy for your effort.

why this is fetching in the order ['e','d','g'] rather than ['d','e','g'].. its ok but just out of curiosity.

[Andriy Ivaneyko]

Python dictionaries are actually are hash tables. Among other things, that means the order of the keys isn't guaranteed or even specified. If you need to get them sorted use sorted(data.keys()) before iterating them.
