Pygame实现小球躲避实例代码
时间：2022-09-24 10:20:37 | 栏目：Python代码 | 点击：次
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

"""
if __name__ == '__main__':
print(banner)

print("[*] 普通：输入 2")
print("[*] 困难：输入 3")

num = int(input("请选择难度："))

else:
print("无法处理～")

如何食用：
把上面4处代码Copy下来在用run.py启动
里面设计的 如何判断；如何重来；… (我觉得我的变量名字已经够清楚了?)
