在Ubuntu 18.04 LTS上Python模組pygame安裝

簡介

Pygame是跨平台Python模組，專為電子遊戲設計，包含影象、聲音。建立在SDL基礎上，允許實時電子遊戲研發而無需被低階語言（如機器語言和組合語言）束縛。

效果截圖如下

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

在命令列上輸入python，再import pygame, 如果沒有報錯，說明python安裝成功。

範例

下面借用網上的例子展示一下效果，給出《飄雪》的動畫效果，背景音樂是陳慧嫻那首《飄雪》
