In Python 3:

Create a table with Suduko puzzle values in it. Pass the table to a display function to display the puzzle similar to how a Sudoku puzzle is printed.

Pre-load your Sudoku table with any Sudoku puzzle values that you come across on line, in the paper, or in books. For instance, in today's paper, the first line of the Sudoku puzzle is: __ __ 8 9 5 __ 1 4 __

so the table might be something like puzzle = [[0,0,8,9,5,0,1,4,0] , [second line values], [third line values]... ] where the 0's represent cells without values. When the table gets printed, spaces are printed rather than the zeros.

Be sure to break your program up into functions. Use your two-dimensional list skills.
