Pygame实现小球躲避实例代码怎么写，相信很多没有经验的人对此束手无策，为此本文总结了问题出现的原因和解决方法，通过这篇文章希望你能解决这个问题。

前言：

这学期的Python课，要写代码是真的多…

课程实验一是一个五子棋，但是发了代码。

至于代码质量嘛～我直接全部根据自己划分的结构改了

这里吐槽下 (真的发下来的代码惨不忍睹 )

我改了快4个小时后面功能不想加了…

这次是自己写嘛～那就写个想样的。

结构划分

我分为了

run 入口

setting 设置

main 主逻辑

utils 仓库

其实我想的是：全部设置到页面上去，但是偷懒～（期末要去弄绩点）

直接开始贴代码

run.py

import sysfrom main import mainbanner = """ ____        _ _ _____          | __ )  __ _| | | ____|___  ___ |  _ \ / _` | | |  _| / __|/ __|| |_) | (_| | | | |___\__ \ (__ |____/ \__,_|_|_|_____|___/\___|"""if __name__ == '__main__':    print(banner)    print("Author: HengYi")    print("[*] 简单：输入 1")    print("[*] 普通：输入 2")    print("[*] 困难：输入 3")    try:        num = int(input("请选择难度："))        if num in [1, 2, 3]:            main(num)        else:            print("无法处理～")            sys.exit()    except Exception as e:        raise Exception("无法处理～")

setting.py
