Python Json fetch key Value

Question

my response content is

{"VoucherQuantityResult":[{"ErrorCode":"E057","ErrorMessage":"IP not registered","Message":"IP not registered","QuantityResponse":[],"ResultType":"FAILED"}]}

responseDetails = response.json() results

{u'VoucherQuantityResult': [{u'ErrorCode': u'E057', u'ResultType': u'FAILED', u'Message': u'IP not registered', u'ErrorMessage': u'IP not registered', u'QuantityResponse': []}]}

then if I call, errorCode = responseDetails['ErrorCode']['ResultType']

there is error KeyError: 'ErrorCode'

I have even used the dumps function, json.dumps(response.json())

then the error is,

TypeError: string indices must be integers, not str

Can some one suggest me how to fetch the keys and values without unicode?

Note: if I use python3 then I dont see any unicode character. still the issue

errorCode = responseDetails['ErrorCode']['value']
KeyError: 'ErrorCode'

Thanks

If you see, your response is a list not a dict which contains dict as its items.

So you can access it like this;

errorCode = responseDetails[0]['ErrorCode']['ResultType']

OR

If this is your whole result;

{u'VoucherQuantityResult': [{u'ErrorCode': u'E057', u'ResultType': u'FAILED', u'Message': u'IP not registered', u'ErrorMessage': u'IP not registered', u'QuantityResponse': []}]}

Then use this;

responseDetails['VoucherQuantityResult'][0]['ErrorCode']['ResultType']

In short, you are not parsing the list but directly trying to jump to the dict

ok one more thing, if I use latest version of python (python3) then I am not getting the unicode character in Json. But still the issue of Key Error. Let me add this to question.

responseDetails = json.loads(response.content) print(responseDetails) errorCode = responseDetails['ErrorCode'] @irfan. I am parsing it

Good to see that you got the answer. BTW unicode in json got removed in latest versions of python (python 3).
