我想构建一个嵌套的序列化程序来显示产品的订单，每个产品都显示其各自的值。我有下面的代码

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

class Order:
    def __init__(self, products):
        self.products = products

    def serialize(self):
        order_data = {}
        order_data['products'] = []

        for product in self.products:
            product_data = {}
            product_data['name'] = product.name
            product_data['price'] = product.price
            order_data['products'].append(product_data)

        return order_data

# 创建产品对象
product1 = Product('Product 1', 10)
product2 = Product('Product 2', 20)

# 创建订单对象
order = Order([product1, product2])

# 序列化订单数据
serialized_order = order.serialize()

# 打印序列化后的订单数据
print(serialized_order)
