>> import distance >> distance.distance(lat1, lon1, lat2, lon2) returns distance in meters as a floating point number
If distance.c is compiled into cDistance.so and can be found for loading, it will be used instead of the Python implementation. To compile the c file, you can, for example, use:
gcc -fPIC -shared -o cDistance.so distance.c
