Program that solves sudokus, comes with few examples and one of the worlds most difficult sudoku
The unsolved sudoku is defined at the beginning as a matrix. I included 4 sudoku examples, the last one is the famous Arto Inkala sudoku.
Once the sudoku is defined, make the program executable (chmod +x sudoku_v4.py) and run it from command line simply by ./sudoku_v4.py
Have fun!
