itertools and amazing speed

[Pedroski55]

Thanks!

I didn't try to make a list of itertools.permutations(images,9), but I did run:

for i in perm_set:
    print(i)

After I'd had breakfast it still hadn't finished, so I did ctrl + c. I hadn't looked at how many permutations 9 from 24 gives!

So how much memory will an iterator or generator object like that occupy, can you give an indication?

@dean Thanks for the function. It will take me a while to digest!
