使用说明
基础版使用
# 快速使用基础版 lottery = SimpleLottery() lottery.add_participants(["张三", "李四", "王五"]) lottery.draw_winner() # 单次抽奖 lottery.draw_multiple(2) # 抽2名获奖者
进阶版特性
- 数据持久化：自动保存参与者信息和获奖记录
- 防重复中奖：已中奖者不会再次被抽中
- 交互式菜单：完整的命令行界面
- 批量操作：支持批量添加参与者
- 奖项命名：可以为每个奖项设置名称
- 抽奖动画：模拟滚动抽奖效果
扩展建议
你可以根据需求进一步扩展：
- GUI界面：使用tkinter或PyQt开发图形界面
- 权重抽奖：为不同参与者设置不同中奖概率
- 定时抽奖：设置定时自动抽奖
- 导出结果：将抽奖结果导出为Excel或CSV
- 多轮抽奖：支持多轮不同奖项的抽奖
- 实时显示：连接大屏幕实时显示抽奖过程
这个抽奖小程序适合年会、活动、课堂等场景使用,你可以直接运行或根据需求修改。
