Extraxt a specific field from a list in python - python-3.x

Question

I am having a list in python. I would like to extract the field countryRegion only. How am I supposed to do that. The code lst['countryRegion'] procduces the error : TypeError: list indices must be integers or slices, not str.
Help me please
[{'__type': 'Location:http://schemas.microsoft.com/search/local/ws/rest/v1',
'address': {'adminDistrict': 'Tamil Nadu',
'adminDistrict2': 'Chennai',
'countryRegion': 'India',
'formattedAddress': 'Chennai, Tamil Nadu',
'locality': 'Chennai'},
'bbox': [12.85071, 79.97689, 13.23403, 80.33292],

Answer 1

Given your input
lst = [{'__type': 'Location:http://schemas.microsoft.com/search/local/ws/rest/v1',
'address': {'adminDistrict': 'Tamil Nadu',
'adminDistrict2': 'Chennai',
'countryRegion': 'India',
'formattedAddress': 'Chennai, Tamil Nadu',
'locality': 'Chennai'},
'bbox': [12.85071, 79.97689, 13.23403, 80.33292],
'confidence': 'High',
'entityType': 'PopulatedPlace',
'geocodePoints': [{'calculationMethod': 'None',
'coordinates': [13.07209, 80.20186],
'type': 'Point',
'usageTypes': ['Display']}],
'matchCodes': ['Good'],
'name': 'Chennai, Tamil Nadu',
'point': {'coordinates': [13.07209, 80.20186], 'type': 'Point'}}]
you get your data from
lst[0]['address']['countryRegion']
First, TypeError is due to lst being a list type and not Dictionary type
Second, countryRegion is not a key of your dictionary, but inside the dictionary value from key address

Answer 2

It is producing that error because of the list containing a single element that is of type dictionary.
so to access the desired value you can just use the command
list_dic = [{'__type': 'Location:http://schemas.microsoft.com/search/local/ws/rest/v1',
'address': {'adminDistrict': 'Tamil Nadu',
'adminDistrict2': 'Chennai',
'countryRegion': 'India',
'formattedAddress': 'Chennai, Tamil Nadu',
'locality': 'Chennai'},
'bbox': [12.85071, 79.97689, 13.23403, 80.33292],
'confidence': 'High',
'entityType': 'PopulatedPlace',
'geocodePoints': [{'calculationMethod': 'None',
'coordinates': [13.07209, 80.20186],
'type': 'Point',
'usageTypes': ['Display']}],
'matchCodes': ['Good'],
'name': 'Chennai, Tamil Nadu',
'point': {'coordinates': [13.07209, 80.20186], 'type': 'Point'}}]
lst_dic[0]['address']['countryRegion']

Answer 3

That's because it is a list of dictionary.
I dont know how you obtain the json but here's what i was able to get:
js=[{'__type': 'Location:http://schemas.microsoft.com/search/local/ws/rest/v1',
'address': {'adminDistrict': 'Tamil Nadu',
'adminDistrict2': 'Chennai',
'countryRegion': 'India',
'formattedAddress': 'Chennai, Tamil Nadu',
'locality': 'Chennai'},
'bbox': [12.85071, 79.97689, 13.23403, 80.33292],
'confidence': 'High',
'entityType': 'PopulatedPlace',
'geocodePoints': [{'calculationMethod': 'None',
'coordinates': [13.07209, 80.20186],
'type': 'Point',
'usageTypes': ['Display']}],
'matchCodes': ['Good'],
'name': 'Chennai, Tamil Nadu',
'point': {'coordinates': [13.07209, 80.20186], 'type': 'Point'}}]
for i in range(len(js)):
print(js[i]["address"]["countryRegion"])
