import requests

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

params = {
    'address': '221B Baker Street, London, United Kingdom',
    'sensor': 'false',
    'region': 'uk'
}

# Do the request and get the response data
req = requests.get(GOOGLE_MAPS_API_URL, params=params)
res = req.json()

# Use the first result
result = res['results'][0]

geodata = dict()
geodata['lat'] = result['geometry']['location']['lat']
geodata['lng'] = result['geometry']['location']['lng']
geodata['address'] = result['formatted_address']

print('{address}. (lat, lng) = ({lat}, {lng})'.format(**geodata))
# 221B Baker Street, London, Greater London NW1 6XE, UK. (lat, lng) = (51.5237038, -0.1585531)
  

After adding the key to params:

params = {
'address': '221B Baker Street, London, United Kingdom',
'sensor': 'false',
'region': 'uk',
'key' : 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX'
}

This is what i get from the terminal output:

Traceback (most recent call last):
File "c:/Users/Documents/google api key print.py", line 24, in
result = res['results'][0]
IndexError: list index out of range
