本文实例为大家分享了python实现kfc点餐收银系统的具体代码，供大家参考，具体内容如下
这个kfc收银系统我实现了的以下功能：
1.正常餐品结算和找零。
2.基本套餐结算和找零。
3.使用优惠劵购买餐品结算和找零。
4.可在一定时间段参与店内活动
5.模拟打印小票的功能（写到文件中）。
工程文件：
肯德基.py文件实现各功能、kfctip.txt文件用于打印小票、picture文件里存放界面所需的图片、其他四个文件为各界面布局。
主界面：
正常餐品点餐界面：
套餐点餐界面：
活动套餐点餐界面：
当点击第二个活动套餐时：
加入订单点击返回后主界面会生成订单信息：
点击结算：
打印小票到文件：
以下是代码实现：
界面布局均使用pyqt5
主界面布局：
