how can i change this number into a sudoku grid format-CodePudding

i have a sudoku generator and the output is like this:

800034065534267891100589304213000706456010000098640502900358000020476109687920050

but i need it to be in this format:

my_sudoku =[
    [9,0,0,0,0,0,0,0,5],
    [0,0,3,6,0,0,0,0,0],
    [0,7,0,0,9,0,2,0,0],
    [0,5,0,0,0,7,0,0,0],
    [0,0,0,0,4,5,7,0,0],
    [0,0,0,1,0,0,0,3,0],
    [0,0,1,0,0,0,0,6,8],
    [0,0,8,5,0,0,0,1,7],
    [7,9,0,8,1,3,4,5,2]]

i need something reverse of this:

def boardToCode(self, input_code=None): 
    if input_code:
        _board = ','.join([str(i) for j in input_code for i in j])
        return _board
    else:
        self.board = ','.join([str(i) for j in self.code for i in j])
        return self.board

but i cannot think of anything.

how can i do this?

CodePudding user response：

this should do

board=[list(map(int, my_sudoku[i:i 9])) for i in range(0, 81, 9)]

CodePudding user response：

How about something like this?

def code_to_board(code):
  nums = [int(i) for i in code]
  board = [nums[i:i   9] for i in range(0, 81, 9)]
  return board
