Python写的俄罗斯方块
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：

from Tkinter import *;
from random import *;
import thread;
from tkMessageBox import showinfo;
import threading;
from time import sleep;

#宽和高

height = 670;
#行和列

cols = 10;
