Re: [docs] Wrong calculation in itertools documentation

Sure, the doc is correct. The count if permutations is n! / (n-r)! Try yourself, please. On Sun, Oct 7, 2012 at 1:29 AM, Sander De Graaf <sander@rotzorg.org> wrote:

Hi,

I'm reading docs.python.org/library/itertools.html @ permutations().

It writes:

The number of items returned is n! / (n-r)! ...

The number should be n! / r!

Thanks, Sander De Graaf
