Sudoku Generator and Solver
SudokuPy solves a board as a human would: by eliminating candidates using a series of deduction techniques, guessing when all clues are exhausted, and repeating until the puzzle is complete.
SudokuPy generates a board by filling in cells, deducing, undoing filling-in of cells if board becomes unsolvable, until a solved board is generated. Then it removes cell values, the number of which is determined by the difficulty setting.
