In the first call, the 0th lambda function is evaluated, and it was defined as the constant function 1. The functions after that each refer to the previous polynomial, so they mess up. The first doesn't so it's fine. I'm new to this, as evidenced by my original posting, so I may be missing something. I hope I helped, Josiah -- http://mail.python.org/mailman/listinfo/python-list
