游戏时间：Skier
首先安装pygame，直接在cmd命令控制框里键入pip install pygame就可以了
代码：
import pygame, sys, random skier_image = ["skier_down.png", "skier_right1.png", "skier_right2.png",

自己照着书上的代码敲了半天...
结果敲出来一堆的bug..
这就很气了，然后改了半天
对着程序看了又看。。字母好多敲错顺序了。。
最后还是没有把自己的程序调通，很难受
最后只能参考别人的程序了qaq
但发现程序都好像是2.7版的
好像一条控制字体显示的语句在3.6改了。。。如下
font = pygame.font.SysFont('arial', 50)#这是调好了的！
#原文中它是这样的 ：font = pygame.font.Font(None, 50）
也百度找了好久。。还好找出来了。。不然就真的要崩溃了
