Me again, I've been sat here for about an hour now staring at this code: # Sudoku # Sudoku is a logic-based number-placement puzzle # The objective is to fill a 9×9 grid with digits so that each column, each row, and each of the nine 3×3 sub-grids that compose the grid contains all of the digits from 1 to 9
[code snipped]
I'm cant figure out how to make it so that each column only has (at most) 1 of each number. I've managed to do it fine for the rows but I'm not sure of how I can do it for the columns. I dont want it to seem like I'm being lazy and just getting you guys to do all the work for me so I'm not necceserily asking for a solution, just advice really.
My advice is don't just stare, do something. Try small pieces of code in the interactive interpreter or run the code through a debugger. FWIW I rarely use a debugger but I'd recommend win pdb, which I believe runs on all platforms despite the name.
