Not sure how to debug this? - rsmldmv - Nov-08-2017

I'm trying to attach a screenshot to my post and can't a way to do this. Is this possible?

Thanks

We don't need screenshots. Copy/paste your code in code tags and the full traceback in error tags. See BBcode for more info.

This code below throws exceptions.

import urllib.parse
import requests
import json

main_api = 'http://maps.googleis.com/maps/api/geocode/json?'

address = 'lhr'
url = main_api + urllib.parse.urlencode({'address': address})

json_data = requests.get(url).json()

print(json_data)

You know that the url address is wrong googleis?
API doc.
For this use Requests.

Here a demo,i use string formatting to make changes in url address.
import requests

address = '1600 Amphitheatre Parkway Mountain View'
api_key = 'Your API key'
url = 'https://maps.googleapis.com/maps/api/geocode/json?address={}{}'.format(''.join(address.split()), api_key)
url_get = requests.get(url)
loc = url_get.json()
What you get back is a Python dictionary also contain list when come from JSON.
Test run.
>>> loc['results'][0]['geometry']
{'bounds': {'northeast': {'lat': 37.42198310000001, 'lng': -122.0853195},
            'southwest': {'lat': 37.4214139, 'lng': -122.0860042}},
 'location': {'lat': 37.4216548, 'lng': -122.0856374},
 'location_type': 'ROOFTOP',
 'viewport': {'northeast': {'lat': 37.4230474802915, 'lng': -122.0843128697085},
              'southwest': {'lat': 37.4203495197085,
                            'lng': -122.0870108302915}}}

>>> loc['results'][0]['geometry']['location']
{'lat': 37.4216548, 'lng': -122.0856374}

>>> loc['results'][0]['geometry']['location']['lat']
37.4216548
