python实现超市进销存管理系统

系统包括7种操作,分别是:1.查询所有商品;2.添加商品;3.修改商品;4.删除商品;5.卖出商品;6.汇总;0.退出系统。

定义一个商品类

#定义一个商品类 

class Goods: 

    def __init__(self,name,num,cin,cout): 

        self.name = name 

        self.num = num

    def __str__(self): 

        state = "已售罄" 

        if self.num == 0: 

            return '名称:%s , 数量:%d %s, 进货价格:%.2f ,售出价格:%.2f '%(self.name,self.num,state,self.cin,self.cout) 

        else

            return '名称:%s , 数量:%d , 进货价格:%.2f ,售出价格:%.2f '%(self.name,self.num,self.cin,self.cout) 

 

定义一个汇总类 

 

#定义一个汇总类 

class gGoods:
