Based on the examples, I presume xrange(x) is every integer up to but not including x. ie 1..^$x in Perl 6, don't recall if that's the Perl 5 syntax or not.

- irahul 14y ago> Based on the examples, I presume xrange(x) is every integer up to but not including x Yes. That makes my Python example incorrect(should be xrange(2, num + 1)) > 1..^$x in Perl 6, don't recall if that's the Perl 5 syntax or not. Perl 5 doesn have 1..^$x. I have always used 1..($n - 1) where I needed it - don't know if there is a better alternative.
- afc 14y ago> Yes. That makes my Python example incorrect(should be xrange(2, num + 1)) Or just xrange(num) and then, as in my original code, output *= num + 1. :-)
- irahul 14y ago> Or just xrange(num) and then, as in my original code, output *= num + 1. :-) HN ate your asterisk(it uses asterisk to mark italics), or something wrong with my chrome app for HN. In your post, I saw: def Factorial(x): output = 1 for i in xrange(x): output = (i + 1) return output
