Python+Pygame实战之俄罗斯方块游戏的实现
木木子学python 人气:0导语
俄罗斯方块，作为是一款家喻户晓的游戏，陪伴70、80甚至90后，度过无忧的儿时岁月
它上手简单能自由组合、拼接技巧也很多。
你知道么，最原始的俄罗斯方块，是长这样婶儿的~
是不是很有童年的味道？今天小编还要给大家，介绍一个全新版本——程序员的版本,期待期待
自从俄罗斯猫被制裁以后，很多人不禁担心起俄罗斯方块的命运。
虽然名字的含俄量很高，但这款游戏圈抗衰老神话肯定不会遭殃，因为它的版权归美国人所有，跟俄罗斯没半毛钱关系。很多玩了半辈子俄罗斯方块的铁子现在多少能理解乔峰当年的心情了吧~
算起来，俄罗斯方块都快39岁高龄了，圈子里比它老的游戏没它好玩，比它好玩的游戏没它老。所以这一款为人类带来无数欢乐的游戏，值得我们更深入的了解。
一、运行环境
小编使用的环境：Python3、Pycharm社区版、,部分自带的就不一一 展示啦。本文主要是一个Turtle版本的。
模块安装：pip install -i http://pypi.douban.com/simple/+模块名
