帮我用python写一个数独游戏

当然可以帮你写一个数独游戏的Python代码！下面是一个简单的实现：

def print_board(board):
    for i in range(9):
        if i % 3 == 0 and i != 0:
            print("- - - - - - - - - - -")
        for j in range(9):
            if j % 3 == 0 and j != 0:
                print("|", end=" ")
            if j == 8:
                print(board[i][j])
            else:
                print(str(board[i][j]) + " ", end="")

def find_empty(board):
    for i in range(9):
        for j in range(9):
            if board[i][j] == 0:
                return (i, j)
    return None

def is_valid(board, num, pos):
    # 检查行
    for i in range(9):
        if board[pos[0]][i] == num and pos[1] != i:
            return False
    # 检查列
    for i in range(9):
        if board[i][pos[1]] == num and pos[0] != i:
            return False
    # 检查小方块
    box_x = pos[1] // 3
    box_y = pos[0] // 3
    for i in range(box_y * 3, box_y * 3 + 3):
        for j in range(box_x * 3, box_x * 3 + 3):
            if board[i][j] == num and (i, j) != pos:
                return False
    return True

def solve_board(board):
    find = find_empty(board)
    if not find:
        return True
    else:
        row, col = find
    for i in range(1, 10):
        if is_valid(board, i, (row, col)):
            board[row][col] = i
            if solve_board(board):
                return True
            board[row][col] = 0
    return False

# 测试代码
board = [
    [0, 0, 0, 0, 0, 0, 0, 0, 0],
    [0, 0, 0, 0, 0, 0, 0, 0, 0],
    [0, 0, 0, 0, 0, 0, 0, 0, 0],
    [0, 0, 0, 0, 0, 0, 0, 0, 0],
    [0, 0, 0, 0, 0, 0, 0, 0, 0],
    [0, 0, 0, 0, 0, 0, 0, 0, 0],
    [0, 0, 0, 0, 0, 0, 0, 0, 0],
    [0, 0, 0, 0, 0, 0, 0, 0, 0],
    [0, 0, 0, 0, 0, 0, 0, 0, 0]
]

solve_board(board)
print_board(board)

这个代码包括了打印数独棋盘、寻找空格、检查数字是否合法、解决数独以及一个简单的测试代码。你可以将这段代码复制到一个Python文件中运行，就可以开始玩数独游戏了。
