在Ubuntu 18.04 LTS上Python模块pygame安装

简介

Pygame是跨平台Python模块，专为电子游戏设计，包含图像、声音。建立在SDL基础上，允许实时电子游戏研发而无需被低级语言（如机器语言和汇编语言）束缚。

效果截图如下

Hello from the pygame community. https://www.pygame.org/contribute.html

在命令行上输入python，再import pygame, 如果没有报错，说明python安装成功。

示例

下面借用网上的例子展示一下效果，给出《飘雪》的动画效果，背景音乐是陈慧娴那首《飘雪》
