需要用python写个命令行俄罗斯方块,在网上搜了一个源码,其中一段代码如下,由于该源码作者是在2.7环境下的,所以代码能实现,但是在2.5不行,求问大神如何改才能在2.5中实现到?
patterns=u"■" #填充花色
def pTurntable():
while True:
for c in patterns:
yield c
nPattern=pTurntable()
print nPattern
cellPattern=next(nPattern)
全部代码如下:
# -*- coding: cp936 -*-

helpInfo=u"""A S D W 操控
Num 1-4 游戏速度
