I meant to add to my last post that even using lambdas this is a weird attempt at a factorial fiunction. Here's the equivalent from my web tutor on functional programming: >>> factorial = lambda n: ( (n <= 1) and 1) or ... (factorial(n-1) * n) >>> factorial(5) 120 It uses the same basic constructs but much less esoteric trickery. Hopefully its slightly more readable, but I still wouldn't recommend it as a way to write everyday code!
