A google search on "distance latitude longitude" will find you a number of pages with the math you need to determine distance, if you know latitude and longitude. http://mathforum.org/library/drmath/sets/select/dm_lat_long.html has links to a few different pages explaining. Another is at http://www.movable-type.co.uk/scripts/LatLong.html . To go from zip codes to latitude and longitude: I vaguely remember that the U.S. Census Bureau had a humongous file with that data. Ah, here you go: http://www.census.gov/geo/www/gazetteer/places2k.html Good luck! _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
