python数独游戏源代码

好的，以下是一个简单的 Python 数独游戏的源代码：

def print_board(board):
    """
    打印数独游戏的当前棋盘
    """
    for i in range(len(board)):
        if i % 3 == 0 and i != 0:
            print("- - - - - - - - - - - - ")

        for j in range(len(board[0])):
            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):
    """
    查找棋盘上的空格
    """
    for i in range(len(board)):
        for j in range(len(board[0])):
            if board[i][j] == 0:
                return (i, j)  # 返回一个元组，表示空格的位置
    return None

def is_valid(board, num, pos):
    """
    判断当前的数字是否在行、列、3x3子区域中都合法
    """
    # 检查行
    for i in range(len(board[0])):
        if board[pos[0]][i] == num and pos[1] != i:
            return False

    # 检查列
    for i in range(len(board)):
        if board[i][pos[1]] == num and pos[0] != i:
            return False

    # 检查 3x3 子区域
    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):
    """
    解决数独游戏
    """
    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):
                return True

            board[row][col] = 0

    return False

# 在主程序中调用上述函数
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]
]

print_board(board)
solve(board)
print("\n解决后：\n")
print_board(board)

这个程序会打印出数独游戏的初始状态，然后调用 `solve()` 函数解决游戏，最后打印出解决后的棋盘状态。你可以根据自己的需要进行调整和修改。
