How to extract a specific data from the json using

2020-03-31 06:14发布

I want to extract the "long_name" data present in the "address_components" in the below given json. The challenge is I want only the "long_name" data whose "types" is "administrative_area_level_2". please let me know how to extract only that specific data preferably in python. Thanks

edit: Note that js["results"][0]["address_components"][2]["long_name"] is not how I want to extract its value since ["address_components"][2] keeps varying for the different locations given as input. my main criteria is to extract data of "long_name" whose "types" is always "administrative_area_level_2"

        }
    ]
}

The below is the code which I am trying but I get output only till location. Let me know what changes I need to make in my code.

import urllib
import json

apiurl= 'http://maps.googleapis.com/maps/api/geocode/json?'

while True:
    address = raw_input('Enter location: ')
    if len(address) < 1 : break

    url = apiurl + urllib.urlencode({'sensor':'false', 'address':     address})
    print 'Retrieving', url
    uh = urllib.urlopen(url).read()

    print 'Retrieved',len(uh),'characters'
    js = json.loads(str(uh))
    print json.dumps(js, indent=4)   
    jayz = js["results"][0]
    lat = jayz["geometry"]["location"]["lat"]
    lng = jayz["geometry"]["location"]["lng"]
    print 'lat',lat,'lng',lng
    location = jayz['formatted_address']
    print location
    components = js["results"][0]["address_components"]
    names = [component['long_name'] for component in components if 'administrative_area_level_2' in component['types']]
    name = names[0]
    print "District:", name

This is one liner solution if you like it

it is in python

my_long_names = [[component.get("long_name") for component  in result.get("address_components") if "administrative_area_level_2" in component.get("types")] for result in data.get("results") ]
print my_long_names

You can get the components and loop on them and find the ones that you

js = eval(input_file.read())
components =  js["results"][0]["address_components"]
names = [component['long_name'] for component in components if 'administrative_area_level_2' in component['types']]

Here, names will include long_name of all the components that have administrative_area_level_2 in their types
