python数字华容道

数字华容道是一个经典的益智游戏，玩家需要将一个n*n的数字方块按照规定的顺序排列，最终使得数字从左到右，从上到下依次递增。下面是一个简单的Python数字华容道的实现：

import random

# 生成随机的n*n数字方块
def generate_board(n):
    nums = list(range(1, n*n))
    nums.append(None)
    random.shuffle(nums)
    board = [nums[i:i+n] for i in range(0, n*n, n)]
    return board

# 找到数字方块中空格的位置
def find_blank(board):
    for i in range(len(board)):
        for j in range(len(board[0])):
            if board[i][j] == None:
                return (i, j)

# 移动数字方块
def move(board, direction):
    i, j = find_blank(board)
    if direction == 'up' and i > 0:
        board[i][j], board[i-1][j] = board[i-1][j], board[i][j]
    elif direction == 'down' and i < len(board)-1:
        board[i][j], board[i+1][j] = board[i+1][j], board[i][j]
    elif direction == 'left' and j > 0:
        board[i][j], board[i][j-1] = board[i][j-1], board[i][j]
    elif direction == 'right' and j < len(board[0])-1:
        board[i][j], board[i][j+1] = board[i][j+1], board[i][j]

# 判断是否完成游戏
def is_finished(board):
    nums = [num for row in board for num in row]
    return nums == list(range(1, len(nums))) + [None]

# 打印数字方块
def print_board(board):
    for row in board:
        print(row)

# 主函数
def main():
    n = int(input("请输入数字华容道的阶数："))
    board = generate_board(n)
    print_board(board)
    while not is_finished(board):
        direction = input("请输入移动方向(up/down/left/right)：")
        move(board, direction)
        print_board(board)
    print("恭喜你完成了游戏！")

if __name__ == '__main__':
    main()
