我是一个典型的 80 后，年老时玩过了特地多的游戏，所以这几天用 Python3+pygame 实现了一个另外小游戏”坦克大战“（其余的游戏，请翻阅我的博客）
本实例代码量有些多，残缺的版本在 1000 行左右（当然了如果再次优化的话 会缩小一部分）
分享进去，心愿能帮忙到大家，毕竟本人做教育行业做了这么多年，还是教育情怀的，哈哈哈哈哈
一、显示成果
二、代码
上面代码用到了一些素材（游戏背景音乐、图片等等），能够到 https://www.itprojects.cn/detail.html?example_id=869a7cbfd9bd4d9b23e61a4d88e39b1c 下载，谢谢大家的反对
残缺代码如下(留神：为了不便下载以及编写更简略，没有采纳多模块的形式，全副代码全副放到 main.py 文件中)
