Thanks Nathan. It would be good to get that kind of detail when you
post
the initial message. Your function didn't look like the usual
factorial
function.
FWIW here is my version :-)
def factorial(n):
result = 1
for x in range(2,n+1):
result *= x
return result
By avoiding while loops you avoid all the mess of trying to maintain
the counter - one of the most common causes of errors in programming!
For a different approach see the recursion topic in my tutor.
