Python Google Maps Driving Time

import googlemaps
from datetime import datetime

gmaps = googlemaps.Client(key='YOUR KEY')


now = datetime.now()
directions_result = gmaps.directions("18.997739, 72.841280",
                                     "18.880253, 72.945137",
                                     mode="driving",
                                     avoid="ferries",
                                     departure_time=now
                                    )

print(directions_result[0]['legs'][0]['distance']['text'])
print(directions_result[0]['legs'][0]['duration']['text'])

This is been taken from here And alternatively you can change the parameters accordingly.

Using URL requests to the Google Distance Matrix API and a json interpreter you can do this:

import simplejson, urllib
orig_coord = orig_lat, orig_lng
dest_coord = dest_lat, dest_lng
url = "http://maps.googleapis.com/maps/api/distancematrix/json?origins={0}&destinations={1}&mode=driving&language=en-EN&sensor=false".format(str(orig_coord),str(dest_coord))
result= simplejson.load(urllib.urlopen(url))
driving_time = result['rows'][0]['elements'][0]['duration']['value']
