pygame介绍

Python Pygame 是一款专门为开发和设计 2D 电子游戏而生的软件包，它支 Windows、Linux、Mac OS 等操作系统，具有良好的跨平台性。Pygame 由 Pete Shinners 于 2000 年开发而成，是一款免费、开源的的软件包，因此您可以放心地使用它来开发游戏，不用担心有任何费用产生。

Pygame 在 SDL（Simple DirectMedia Layer，使用 C语言编写的多媒体开发库） 的基础上开发而成，它提供了诸多操作模块，比如图像模块（image）、声音模块（mixer）、输入/输出（鼠标、键盘、显示屏）模块等。相比于开发 3D 游戏而言，Pygame 更擅长开发 2D 游戏，比如于飞机大战、贪吃蛇、扫雷等游戏。

安装pygame

pip install pygame

pygame入门案例

import pygame
import sys

pygame.init()  # 初始化pygame
size = width, height = 320, 240  # 设置窗口大小
screen = pygame.display.set_mode(size)  # 显示窗口

while True:  # 死循环确保窗口一直显示
    for event in pygame.event.get():  # 遍历所有事件
        if event.type == pygame.QUIT:  # 如果单击关闭窗口，则退出
            sys.exit()

pygame.quit()  # 退出pygame
