Thanks for your example Roy, that illustrates well what I'm after: self.lat = lat "ellipsoid reference: WGS84\nGRS 80 no longer supported" It does exactly what its intended to do: i had no clue what the World Geodetic System and would have asserted my input with a GRS80_2_WGS84 function Little notes to avoid major mistakes. class landClimateOrbiter(NASA): self.speed = self.unit * x Just imagine 'feet' would have popped up when typing self.unit -- http://mail.python.org/mailman/listinfo/python-list
