this is what i come up with
class ShoppingCart:
items = {}
def __init__(self, total = 0):
self.total = total
def add_item(self, item_name, quantity, price):
self.item_name = item_name
self.quantity = quantity
self.price = price
if not item_name in self.items:
self.items[item_name] = quantity
total = self.price*self.quantity + self.total
self.items[self.item_name] = self.quantity
def remove_item(self, item_name, quantity, price):
self.item_name = item_name
self.quantity = quantity
self.price = price
total = self.total - price*quantity
if item_name in self.items:
del self.items[item_name]
return self.items
def checkout(self, cash_paid):
self.cash_paid = cash_paid
return self.total - cash_paid
if cash_paid < self.total:
return "Cash paid not enough"
class Shop(ShoppingCart):
def __init__(self):
self.quantity = 100
def remove_item(self, quantity):
self.quantity -= quantity
return self.quantity
