编写一个python代码,利用Gui的 tkinter库设计一个4*4的华容道游戏。 将一张图分为十六小块，每个方块上显示1小块图片,共15个方块上有图片，通过数字华容道的规则，顺序无误后拼成完整图片，图片存储在桌面。

好的，以下是实现该游戏的 Python 代码：

from tkinter import *
from PIL import Image, ImageTk
import random

# 定义常量
WIDTH = 400
HEIGHT = 400
GRID_SIZE = 4
GRID_LEN = WIDTH // GRID_SIZE
IMAGE_PATH = "path/to/image.jpg"
BLANK = (GRID_SIZE-1, GRID_SIZE-1)

class Puzzle(Frame):
    
    def __init__(self, parent):
        Frame.__init__(self, parent)
        
        # 加载图片并裁剪成小块
        self.image = Image.open(IMAGE_PATH)
        self.tiles = []
        for i in range(GRID_SIZE):
            row = []
            for j in range(GRID_SIZE):
                x0, y0 = j*GRID_LEN, i*GRID_LEN
                x1, y1 = x0+GRID_LEN, y0+GRID_LEN
                tile = self.image.crop((x0, y0, x1, y1))
                row.append(tile)
            self.tiles.append(row)
        
        # 添加标签和事件处理程序
        self.labels = []
        for i in range(GRID_SIZE):
            row = []
            for j in range(GRID_SIZE):
                if (i, j) == BLANK:
                    label = Label(self, width=GRID_LEN, height=GRID_LEN, bg="white")
                else:
                    tile = self.tiles[i][j]
                    photo = ImageTk.PhotoImage(tile)
                    label = Label(self, image=photo)
                    label.image = photo
                    label.bind("<Button-1>", lambda event, i=i, j=j: self.move(i, j))
                row.append(label)
                label.grid(row=i, column=j)
            self.labels.append(row)
        
        # 添加按钮
        Button(self, text="Shuffle", command=self.shuffle).grid(row=GRID_SIZE, column=0, columnspan=GRID_SIZE, pady=10)
        
        # 初始化游戏
        self.shuffle()
    
    def shuffle(self):
        # 随机打乱拼图
        for i in range(100):
            moves = self.get_moves()
            i, j = random.choice(moves)
            self.move(i, j)
    
    def move(self, i, j):
        # 移动块
        moves = self.get_moves()
        if (i, j) in moves:
            self.tiles[i][j], self.tiles[BLANK[0]][BLANK[1]] = self.tiles[BLANK[0]][BLANK[1]], self.tiles[i][j]
            self.labels[i][j], self.labels[BLANK[0]][BLANK[1]] = self.labels[BLANK[0]][BLANK[1]], self.labels[i][j]
            self.labels[i][j].grid(row=BLANK[0], column=BLANK[1])
            self.labels[BLANK[0]][BLANK[1]].grid(row=i, column=j)
            BLANK = (i, j)
    
    def get_moves(self):
        # 获取可移动方向
        moves = []
        i, j = BLANK
        if i > 0: moves.append((i-1, j))
        if i < GRID_SIZE-1: moves.append((i+1, j))
        if j > 0: moves.append((i, j-1))
        if j < GRID_SIZE-1: moves.append((i, j+1))
        return moves

if __name__ == "__main__":
    root = Tk()
    root.title("Puzzle Game")
    puzzle = Puzzle(root)
    puzzle.pack(fill=BOTH, padx=20, pady=20)
    root.mainloop()

该代码使用了 tkinter 和 PIL 库，首先将图片裁剪成小块，并将每个小块分别添加到标签中。然后，使用 `shuffle` 函数随机打乱拼图，使用 `move` 函数移动块，使用 `get_moves` 函数获取可移动方向。最后，在 `main` 函数中创建游戏窗口并运行游戏。
