Python Geocoding Toolboxhttp://code.google.com/p/geopy
geopy makes it easy for developers to locate the coordinates of addresses, cities,
countries, and landmarks across the globe using third-party geocoders and other data
sources, such as wikis.
geopy currently includes support for six geocoders: Google Maps, Yahoo! Maps, Windows
Local Live (Virtual Earth), geocoder.us, GeoNames, MediaWiki pages (with the GIS
extension), and Semantic MediaWiki pages.
