Pygame是一個(gè)利用SDL庫的寫就的游戲庫，SDL呢，全名Simple DirectMedia Layer，是一位叫做Sam Lantinga的大牛寫的，據(jù)說他為了讓Loki（致力于向Linux上移植Windows的游戲的一家大好人公司，可惜已經(jīng)倒閉，唉好人不長命啊……）更有效的工作，創(chuàng)造了這個(gè)東東。
SDL是用C寫的，不過它也可以使用C++進(jìn)行開發(fā)，當(dāng)然還有很多其它的語言，Pygame就是Python中使用它的一個(gè)庫。Pygame已經(jīng)存在很多時(shí)間了，許多優(yōu)秀的程序員加入其中，把Pygame做得越來越好。
