Two classes

#item and sale and receipt

class item:

        self.name=name
        self.price=price
        
    def getName(self):

    def getPrice(self):
        return self.price
    

class cart:
    def __init__(self):
        self.items=[]
        
    def addItem(self, product):
        self.items.append(product)

    def getTotal(self):
        total=0
        for i in self.items:

    c=cart()
