project kudoSudoku follows SUDO project

[sylas]

I must add a very important thing. When you see on the prompt command " Hit ENTER to continue": remove tkinter figure clicking on its cross(corner up and right). So, I will rather modify "Hit ENTER to continue" to "Remove first tkinter figure and then click ENTER to continue(on the Command Prompt)"

 def printSUDOKU(self, matrix):
        pprint(matrix)
        for i in range(9):
            for j in range(9):
                if matrix[i][j]==' ':
                    matrix[i][j]=0
                else:
                    matrix[i][j]=int(matrix[i][j])

        puzzle=matrix
        print("puzzle")
        pprint(puzzle)
        with open('numbers.csv', 'w', newline='') as csvfile:
            numwriter=csv.writer(csvfile, delimiter=' ', quotechar='|', quoting=csv.QUOTE_MINIMAL)
            numwriter.writerow(puzzle)

        input("Hit ENTER to continue")

    def printALL(self):
        print('Sudoku:')

I think this project can be improved, because there are people much stronger than me on python language.
