Hi I have tried now for ages to make a loop that does the following: Makes a new list with 9 random values, from 9 different lists, with 9 elements. And makes sure that none of the elements repeat! Is there anyone that can help, with a very simple solution?? Best Christian

Sounds like a homework question to me. You've tried. What code have you come up with, and to what extent does it fall short of your goal? The nine different lists - do they have unique elements? Are you able to use sets? (If you haven't been taught what a set is, the answer's probably no.) ChrisA

I'm sure that there is a simple solution but I don't fully understand your problem could you perhaps provide an example with actual numbers (perhaps use 3 instead of 9 so it's easier to follow)? In any case I suspect that you want something involving range() and random.shuffle() if that helps. Oscar
