Python版植物大战僵尸
已有的植物：向日葵，豌豆射手，坚果墙，寒冰射手，樱桃炸弹，双发射手，三线射手，大嘴花，小喷菇，土豆雷，地刺，胆小菇，倭瓜，火爆辣椒，阳光菇，寒冰菇，魅惑菇，火炬树桩，睡莲，杨桃，咖啡豆，海蘑菇，高坚果，缠绕水草，毁灭菇，墓碑吞噬者，大喷菇，大蒜，南瓜头已有的僵尸：普通僵尸，旗帜僵尸，路障僵尸，铁桶僵尸，读报僵尸，橄榄球僵尸，鸭子救生圈僵尸，铁门僵尸，撑杆跳僵尸，冰车僵尸，潜水僵尸支持选择植物卡片支持白昼模式，夜晚模式，泳池模式，浓雾模式（暂时没有加入雾），传送带模式和坚果保龄球模式支持背景音乐播放
支持调节音量 支持音效
支持与背景音乐一起调节音量 支持全屏模式
按F键进入全屏模式，按U键恢复至窗口模式 支持用小铲子移除植物支持分波生成僵尸支持“关卡进程”进度条显示夜晚模式支持墓碑以及从墓碑生成僵尸含有泳池的模式支持在最后一波时从泳池中自动冒出僵尸
环境要求
Python3 （建议 >= 3.10，最好使用最新版）Python-Pygame （建议 >= 2.0，最好使用最新版）
方法
使用鼠标收集阳光,种植植物
