Pygeocode leverages multiple public geocoding APIs including Google's Geocoding API and Yahoo's Place Finder. Having several APIs available is specially useful when the user has reached one API's rate limit or when an API returns ambiguous results, or no results at all.

You can use pip or easy_install

• pip install pygeocode
• easy_install pygeocode

Using Google's Geocoding API:

from pygeocode import geocoder

address = '1600 Amphitheatre Pkwy, Mountain View, CA'
res = geocoder.geocode_google(address)
print res['lat'], res['lng']

Using Yahoo's Place Finder API:

from pygeocode import geocoder

app_id = <you_app_id>
address = '1600 Amphitheatre Pkwy, Mountain View, CA'
res = geocoder.geocode_yahoo(address, app_id)
print res['lat'], res['lng']

Full example:

import optparse
import functools
import logging

from pygeocode import geocoder

log = logging.getLogger(__name__)

def main(address, appid=None):
    yahoo_geocoder = functools.partial(
        geocoder.geocode_yahoo,
        appid=appid,
        )
    geocoders = [yahoo_geocoder, geocoder.geocode_google]
    for geocoder_ in geocoders:
        try:
            res = geocoder_(address)
        except geocoder.GeocoderError, e:
            log.error(str(e))
        else:
            return res

if __name__ == '__main__':
    parser = optparse.OptionParser(
        usage='%prog ADDRESS [OPTS]',
        )
    parser.add_option(
        '--yahoo-appid',
        help='The Yahoo Application ID to be used in the API call',
        )

    parser.set_defaults(
        verbose=False,
        )

    options, args = parser.parse_args()
    try:
        (address,) = args
    except ValueError:
        parser.error('Wrong number of arguments.')

    if res:
        out = '"{address}" is at coordinates {lat},{lng}'.format(
            address=address,
