I'll try the 'very easy' answer: yes, there is probably code somewhere to draw a parabola or curve. Have you tried making a start on this yourself? Did you run into a problem? Or perhaps: did you try googling for 'draw parabola' or 'parabola equation'?
If you've not made a start on attempting this problem, and need help, try breaking down your help request into sub-requests. Like, you might be wondering what the algorithm or maths is for drawing a parabola/curve. Or you might be wondering about how to display a curve on screen. (Ascii output? Generating an image file like a gif? Output to a window using a GUI toolkit like wxPython?) Or are you just expecting someone to post fully functional code from a vague request? The following is highly recommended reading. It's called "How to ask questions the smart way": http://www.catb.org/~esr/faqs/smart-questions.html best of luck! alex _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
