PS：最近学习用Python怎么写小游戏，研究了几个俄罗斯方块的代码。记录一下：
第二个实现代码如下，这个使用了内置的模块实现的，在PY2.7版本直接运行，在3.x版本需要修改部分语法：
#!/usr/bin/python
# -*- coding: utf-8 -*-
from Tkinter import *
import random
from tkMessageBox import askquestion
# 尚需改进，有待提高
# 各种方块的表示，与参考方块的相对位置
shapedic = {1: ((0, 0), (1, 0), (0, -1), (1, -1)), # 正方形
2: ((0, 0), (0, -1), (0, -2), (0, 1)), # 长条
3: ((0, 0), (0, -1), (1, 0), (1, 1)), # 之字型
4: ((0, 0), (0, -1), (-1, 0), (-1, 1)), # 反之字型
5: ((0, 0), (1, 0), (-1, 0), (-1, -1)), # L型
6: ((0, 0), (1, 0), (-1, 0), (1, -1)), # 反L型
7: ((0, 0), (1, 0), (-1, 0), (0, -1)) # T型
}
# 旋转函数，顺时针旋转90度，相对于参考方块
change_dic = {(0, 0): (0, 0), (0, 1): (-1, 0), (-1, 0): (0, -1), (0, -1): (1, 0), (1, 0): (0, 1),
(1, -1): (1, 1), (1, 1): (-1, 1), (-1, 1): (-1, -1), (-1, -1): (1, -1),
(2, 0): (0, 2), (0, 2): (-2, 0), (-2, 0): (0, -2), (0, -2): (2, 0)}

注意：这个程序依赖图形界面，要在图形界面上才能正常运行，win和Linux的图形界面都可以。在纯终端命令界面是不能正常运行的。
