How to design a virtual currency and mall system that supports online quizzes
With the development and popularization of online education, more and more people choose to use the Internet Participate in online quizzes. However, in order to increase user enthusiasm and participation, simply providing answers cannot meet their needs. Therefore, it is becoming increasingly important to design a virtual currency and mall system that supports online quizzes. By introducing virtual currency and mall systems, more rewards and incentives can be provided to users, and more profit opportunities can be created for website owners.
The following is a reference design plan for implementing a virtual currency and mall system that supports online question answering:
In the mall system, each product should have the following attributes:
Code example:
The following is a simple code example to illustrate how to implement virtual currency circulation and recharge functions in virtual currency and mall systems.
class User: def __init__(self, name, balance): self.name = name self.balance = balance def increase_balance(self, amount): self.balance += amount def decrease_balance(self, amount): self.balance -= amount def get_balance(self): return self.balance class VirtualCurrency: def __init__(self, name): self.name = name def transfer(self, sender, receiver, amount): if sender.get_balance() >= amount: sender.decrease_balance(amount) receiver.increase_balance(amount) def recharge(self, user, amount): user.increase_balance(amount) class Shop: def __init__(self, name, price): self.name = name self.price = price def buy(self, user, currency): if user.get_balance() >= self.price: user.decrease_balance(self.price) return True else: return False # 创建用户 user1 = User("Tom", 100) user2 = User("Alice", 50) # 创建虚拟货币 currency = VirtualCurrency("Coin") # 充值 currency.recharge(user1, 50) # 转账 currency.transfer(user1, user2, 30) # 购买商品 shop1 = Shop("Book", 20) shop2 = Shop("Cup", 10) if shop1.buy(user1, currency): print("购买成功") else: print("余额不足") if shop2.buy(user2, currency): print("购买成功") else: print("余额不足")
This is just a simple example. The actual system requires more functions and details to meet the needs of users and the operational needs of the mall. I hope the above design plans and code examples can be helpful to you, and I wish you a smooth implementation of your online question answering project!
