Thanks for that. That's the answer. visual python is an fine programme for generating 3D objects (http:// www.vpython.org/) which generates an image from simple python code. import visual a = visual.sphere() generates a window with a 3D lit rendering of a white sphere which you can easily fly around with the mouse. a.blue = 0 makes it a yellow sphere and a.x = 1 moves it one unit along the x axis. I'm using it to create a visual representative of objects stored in the database, so I'm mapping the database objects to visual objects. Thanks once again. I hadn't considered eval, but once it's pointed out, it's obvious. Chris -- http://mail.python.org/mailman/listinfo/python-list
