小编给大家分享一下python基于pygame实现俄罗斯方块的方法，希望大家阅读完这篇文章之后都有所收获，下面让我们一起去探讨吧！
一、简单说明
90后的小伙伴都玩过“俄罗斯方块”，那种“叱咤风云”场景 偶尔闪现在脑海 真的是太爽了；如果没有来得及玩过的同学，这次可以真正的自己做一个了
本实例用的是Python3（当然了Python3.5 3.6 3.7....都行 ）+ pygame实现的
运行之前需要安装pygame模块，安装命令如下
pip install pygame -i https://mirrors.aliyun.com/pypi/simple/二、运行效果
三、完整代码
文件main.py代码如下：
