Pygame
绘制图形，显示图片，动画效果，与键盘、鼠标、游戏手柄等外设交互，播放声音
创建Surface对象，即Pygame里图像的对象
pygame可以设置帧率
clock = pygame.time.Clock()
clock.tick(200)#200运行速度
set_mode(resolution=(0,0),flags=0,depth=0) -> Surface对象
第一个参数尺寸大小
第二个参数:指定扩展选项，如全屏
第三个参数：指定颜色的位数（32），一般默认，python会自动根据当前操作系统选值
FULLSCREEN 全屏模式
DOUBLEBUF 双缓冲模式
HWSURFACE 硬件加速支持（只有在全屏模式下才能使用）
OPENGL 使用OpenGL渲染（3D模式使用）
PESIZABLE 使得窗口可以调整大小
NOFRAME 使得窗口没有边框和控制按钮
- 事件

import pygame
import sys
#初始化Pygame
pygame.init()

bg = (0,0,0)

line_height = font.get_linesize()
