python实现俄罗斯方块游戏

在公司实习。公司推崇Python和Django框架，所以也得跟着学点。

简单瞅了下Tkinter，和Canvas配合在一起，还算是简洁的界面开发API。threading.Thread创建新的线程，其多线程机制也算是方便。

只是canvas.create_rectangle居然不是绘制矩形，而是新建了矩形控件这点让人大跌眼镜。先开始，在线程里每次都重绘多个矩形（随数组变化），其实是每次都新建了N个矩形，结果内存暴增。原来，对矩形进行变更时，只需用canvas.itemconfig即可。

下面就是截图（时间太晚，明日还得上班，做得非常粗糙...没事时再慢慢修正）。

而代码如下：

#coding=utf-8
from Tkinter import *;
from random import *;
import thread;
from tkMessageBox import showinfo;
import threading;
from time import sleep;
class BrickGame(object):

 start = True;
 #是否到达底部
 isDown = True; 

 #窗体

 #frame
 frame1 = None; 

 #绘图类
 canvas = None; 

 #标题
 title = "BrickGame";
 #宽和高
 width = 350;
 height = 670; 

 #行和列
 rows = 20;
 cols = 10; 

 #几种方块

估计用图形界面会很少，因为本人是WEB开发。不过，怎样也抑制不住这颗喜欢写游戏的心啊！
