注：程序的第83行和第89行的图片位置一定要选择正确；改变a的值可以设置拼图分成多少块；所选图片分辨率过大会使拼图布满整个电脑屏幕，剪切一下就好了；需要先下载pygame, sys, random库，下载方法和下面程序封装方法的1步骤一样，只需将pyinstall改变就好了，其它库函数的下载方法相同。

程序封装方法：

1.安装打包工具：同时按住win+R打开运行对话框，输入cmd点击确定，输入pip install pyinstall按下回车键，进行安装。

2.打开命令提示符输入pyinstaller -F -w python源代码位置名称（例如D：\桌面\拼图.py） --distpath=D:\桌面。一定要注意空格！

3.打开后缀为.exe的文件

4.发送给好友，只能在电脑上运行
