A Python clone of Victor Jalencas's whereami utility, which uses CoreLocation services on OS X to determine your geographical coordinates. It requires OS X 10.6 (Mountain Lion) or later to function.
Kudos to Rich Healey for getting me started.
$ pip install doko
Enabling Core Location
On OS X 10.6 (Mountain Lion) or later, you can enable Core Location in System Preferences, in the "Security" or "Security & Privacy" section.
Using as a module
> import doko > doko.whereami() Location(latitude=35.674851, longitude=139.701419)
Using on the command-line
$ doko 35.674851 139.701419
