I was playing around with the code, but got nowhere.
Did you get an error? What was it? Please show the entire error message, including the stack trace, when you have a question about an error. What is the value of (b*b - 4*a*c) ? Does that give you a hint? Kent _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
