python+pyqt5實(shí)現(xiàn)KFC點(diǎn)餐收銀系統(tǒng)
更新時(shí)間：2019年01月24日 11:25:04 作者：dcjmessi
這篇文章主要為大家詳細(xì)介紹了python+pyqt5實(shí)現(xiàn)KFC點(diǎn)餐收銀系統(tǒng)，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下
本文實(shí)例為大家分享了python實(shí)現(xiàn)KFC點(diǎn)餐收銀系統(tǒng)的具體代碼，供大家參考，具體內(nèi)容如下
這個(gè)kfc收銀系統(tǒng)我實(shí)現(xiàn)了的以下功能：
1.正常餐品結(jié)算和找零。
2.基本套餐結(jié)算和找零。
3.使用優(yōu)惠劵購(gòu)買餐品結(jié)算和找零。
4.可在一定時(shí)間段參與店內(nèi)活動(dòng)
5.模擬打印小票的功能（寫到文件中）。
工程文件：
肯德基.py文件實(shí)現(xiàn)各功能、kfctip.txt文件用于打印小票、picture文件里存放界面所需的圖片、其他四個(gè)文件為各界面布局。
主界面：
正常餐品點(diǎn)餐界面：
套餐點(diǎn)餐界面：
活動(dòng)套餐點(diǎn)餐界面：
當(dāng)點(diǎn)擊第二個(gè)活動(dòng)套餐時(shí)：
加入訂單點(diǎn)擊返回后主界面會(huì)生成訂單信息：
點(diǎn)擊結(jié)算：
打印小票到文件：
以下是代碼實(shí)現(xiàn)：
界面布局均使用pyqt5
