Terry, since you're talking about "the rabbit problem", are you sure you're talking about the factorial example? It sounds like you're talking about the Fibonacci example. I agree with Daniel about the factorial function: there's no disagreement about 0!=1, 1!=1, 2!=2, 3!=6, 4!=24, ..., that I've ever seen. The first two terms in a Fibonacci sequence are indeed arbitrary, though. -- http://mail.python.org/mailman/listinfo/python-list
