I've tried itertools.combinations, but that gets subsequences. I've also tried random.shuffle, but that's horribly inefficient with multiple repeats. Is there an algorithm to solve this? Webwork out how many numbers 100000 to 999999 there are without repetition - first off, it starts with a digit from 1 - 9, then you choose 5 digits from 0 - 9 (excluding digit 1 that was chosen) so that is 5 from 9 - then jumbled 5! ways - then you subtract this from count of all numbers 100000 to 999999 – Cato Sep 12, 2016 at 16:11 bite toothpaste tablets uk
