Geopy

The OpenBlock geocoder is powerful and robust. It uses PostGIS for spacial queries, can extract addresses from bodies of text, and can understand block and intersection notation. We've run into a few issues with it, however, including a low geocoding success rate. This is a tough problem to solve and depends on a lot of factors (the extent of street and block data in OpenBlock, format of the street addresses, etc.), so your mileage may vary. Below I constructed a simple test using Google's Geocoding API to have as an alternative.
