Re: list question... unique values in all possible unique spots

Thank you for all your responses. I've tried the permutations road (thank you to all those of you who have suggested it) and it takes %*& %^ long :-) As expected. I've solved it a different way, which runs through the 26 spots by just adding one at a time if available. Still takes a long time, but

Mensanator: > Ever tried to iterate 403 septillion times? The OP is talking about formulas, like: X + Y * Z = W Where X, Y, Z, W distinct and in [1, 26], so you have C(26, 4) combinations that's way less than 26! >>> binomial(26, 4) 14950 So this can be solved with a xcombinations() generator.

I'm wondering how to do this the most elegant way: I found this quiz in some magazine. I've already solved it on paper, but want to write a python program to solve it. It comes down to being able to represent range(1,27) through a number of formulas. How do I write a loop that will loop through thi
