python点餐系统早餐_python+pyqt5实现KFC点餐收银系统

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
