如何从序列化程序获取最低和最高价格？

{
  "products": [
    {
      "name": "Product 1",
      "price": 10.99
    },
    {
      "name": "Product 2",
      "price": 9.99
    },
    {
      "name": "Product 3",
      "price": 12.99
    }
  ]
}

import json

# 假设data为序列化后的JSON字符串
data = '''
{
  "products": [
    {
      "name": "Product 1",
      "price": 10.99
    },
    {
      "name": "Product 2",
      "price": 9.99
    },
    {
      "name": "Product 3",
      "price": 12.99
    }
  ]
}
'''

# 解析JSON数据
parsed_data = json.loads(data)

# 初始化最低和最高价格
min_price = float('inf')
max_price = float('-inf')

# 遍历产品列表
for product in parsed_data["products"]:
    price = product["price"]
    
    # 更新最低和最高价格
    min_price = min(min_price, price)
    max_price = max(max_price, price)

# 打印结果
print("最低价格：", min_price)
print("最高价格：", max_price)
