python - 在矩阵中生成数独谜题而不是绘制 GUI

Question

该程序的概念是创建一个可以通过 pygame 解决的数独谜题。我被卡住的地方是这个错误:

Traceback (most recent call last):
  File "C:\Users\Lenovo\Desktop\Sudoku Solver\GUI.py", line 307, in <module>
    main()
  File "C:\Users\Lenovo\Desktop\Sudoku Solver\GUI.py", line 245, in main
    board = Grid(9, 9, 540, 540)
  File "C:\Users\Lenovo\Desktop\Sudoku Solver\GUI.py", line 105, in __init__
    self.cubes = [[Cube(self.board[i][j], i, j, width, height) for j in range(cols)] for i in range(rows)]
  File "C:\Users\Lenovo\Desktop\Sudoku Solver\GUI.py", line 105, in <listcomp>
    self.cubes = [[Cube(self.board[i][j], i, j, width, height) for j in range(cols)] for i in range(rows)]
  File "C:\Users\Lenovo\Desktop\Sudoku Solver\GUI.py", line 105, in <listcomp>
    self.cubes = [[Cube(self.board[i][j], i, j, width, height) for j in range(cols)] for i in range(rows)]
TypeError: 'int' object is not subscriptable
[Finished in 0.6s with exit code 1]

但有趣的是，当我传入一个手工制作的矩阵时，没有错误。我可以复制生成的矩阵并将其传入，它会起作用，但制作一个像下面这样的函数来生成一个不会。

def generate_board():
    base  = 3
    side  = base*base

    def pattern(r,c): return (base*(r%base)+r//base+c)%side

    from random import sample
    def shuffle(s): return sample(s,len(s)) 
    rBase = range(base) 
    rows  = [ g*base + r for g in shuffle(rBase) for r in shuffle(rBase) ] 
    cols  = [ g*base + c for g in shuffle(rBase) for c in shuffle(rBase) ]
    nums  = shuffle(range(1,base*base+1))

    # produce board using randomized baseline pattern
    board = [ [nums[pattern(r,c)] for c in cols] for r in rows ]

    squares = side*side
    empties = squares * 3//4
    for p in sample(range(squares),empties):
        board[p//side][p%side] = 0

    numSize = len(str(side))
    for line in board: return line


generated_board = generate_board()

为了更好地了解程序，请查看问题所在的部分，即为每个 self.cubes 创建一个立方体对象的 GRID 类的初始化:

class Grid:
    board = generated_board   
  

    def __init__(self, rows, cols, width, height):
        self.rows = rows
        self.cols = cols
        self.cubes = [[Cube(self.board[i][j], i, j, width, height) for j in range(cols)] for i in range(rows)]
        self.width = width
        self.height = height
        self.model = None
        self.selected = None

我不认为这是必需的，但这是在 Grid 类的初始化中以 9x9 方式创建的 Cube 类。

    class Cube:
        rows = 9
        cols = 9

    def __init__(self, value, row, col, width ,height):
        self.value = value
        self.temp = 0
        self.row = row
        self.col = col
        self.width = width
        self.height = height
        self.selected = False

    def draw(self, win):
        fnt = pygame.font.SysFont("comicsans", 40)

        gap = self.width / 9
        x = self.col * gap
        y = self.row * gap

        if self.temp != 0 and self.value == 0:
            text = fnt.render(str(self.temp), 1, (128,128,128))
            win.blit(text, (x+5, y+5))
        elif not(self.value == 0):
            text = fnt.render(str(self.value), 1, (0, 0, 0))
            win.blit(text, (x + (gap/2 - text.get_width()/2), y + (gap/2 - text.get_height()/2)))

        if self.selected:
            pygame.draw.rect(win, (255,0,0), (x,y, gap ,gap), 3)

    def set(self, val):
        self.value = val

    def set_temp(self, val):
        self.temp = val

所以再次传入一个板子

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

会做这项工作，董事会在网格类中传递。但是在课外生成一个，然后即使生成的板采用这种确切的格式，也不会将其插入上面的错误中。请任何有这种问题或知道如何调试的人来帮助我，非常感谢

当您生成板时，您只返回第一行而不是整个板。
在您的代码中进行此更改:

def generate_board():
    .........
    # for line in board: return line  # remove this line
    return board   # return full board
