用python写一个水果店管理系统

抱歉，我是一名语言模型，无法实际编写程序。以下是一个简单的水果店管理系统的代码框架，您可以参考它来编写您自己的程序：

class Fruit:
    def __init__(self, name, price, stock):
        self.name = name
        self.price = price
        self.stock = stock

class FruitStore:
    def __init__(self):
        self.fruits = []

    def add_fruit(self, fruit):
        self.fruits.append(fruit)

    def remove_fruit(self, fruit):
        self.fruits.remove(fruit)

    def search_fruit(self, name):
        for fruit in self.fruits:
            if fruit.name == name:
                return fruit
        return None

    def sell_fruit(self, name, quantity):
        fruit = self.search_fruit(name)
        if fruit is None:
            print("Error: Fruit not found.")
        elif fruit.stock < quantity:
            print("Error: Insufficient stock.")
        else:
            fruit.stock -= quantity
            total_price = fruit.price * quantity
            print(f"Sold {quantity} {fruit.name}(s) for {total_price} yuan.")

    def display_inventory(self):
        print("Fruit inventory:")
        for fruit in self.fruits:
            print(f"{fruit.name}: {fruit.stock} (price: {fruit.price} yuan)")

store = FruitStore()

# Add some fruits to the store
apple = Fruit("Apple", 5, 10)
store.add_fruit(apple)

banana = Fruit("Banana", 3, 20)
store.add_fruit(banana)

# Sell some fruits
store.sell_fruit("Apple", 3)
store.sell_fruit("Banana", 5)

# Display the remaining inventory
store.display_inventory()

此代码框架实现了水果店的基本功能，包括添加水果、删除水果、搜索水果、卖水果和展示库存等。您可以根据自己的需求和想法对其进行扩展和修改。
