 If cpp is fine with you .. I would suggest osrm (
 http://project-osrm.org/ ). Its an excellent tool for route
 computation  and can return various standard formats (KML,JSON,GPX ).
 It also provides a web service for querying and you can parse the json
 u get after querying from your python code. 

thanks - it's good. Btw, how does one get json? I only see kml.

hi,

I need a command line tool to get the distance between two points by the
shortest route - preferably in python. Recommendations?

Hi K,

The wiki[1] is a good starting point. There is also a more specific 
mailing list[2] dedicated to routing.


Regards,

Jorge

Ok, I never tryed the guy (or did, but with errors). However PyrouteLib 
works well, I use it there: www.pistes-nordiques.org.
You'll find the simplified pyroutelib I uses on the website in
