With these it helps i have a text file like this , You could do it like this using index slicing and zip:
infile = open('./Desktop/nums.txt')

board = infile.read().strip('\\n').split(',')
# the numbers are in string format at this point
# board ['1', ' 2', ' 3', ' 4', ' 5', ' 6', ' 7', ' 8', ' 9']
board_array = [[int(x),int(y),int(z)] for x,y,z in zip(board[::3], board[1::3], board[2::3])]
>>> board_array
[[1, 2, 3], [4, 5, 6], [7, 8, 9]]
