如何将此JSON格式转换为模型类，并使用改进将响应转换为列表

{
  "id": 1,
  "name": "John Doe",
  "age": 25
}

class Person:
    def __init__(self, id, name, age):
        self.id = id
        self.name = name
        self.age = age

import json

json_str = '{"id": 1, "name": "John Doe", "age": 25}'
data = json.loads(json_str)

person = Person(**data)

[
  {
    "id": 1,
    "name": "John Doe",
    "age": 25
  },
  {
    "id": 2,
    "name": "Jane Smith",
    "age": 30
  }
]

response_data = json.loads(response_json)

person_list = []
for item in response_data:
    person = Person(**item)
    person_list.append(person)

class Person:
    def __init__(self, id: int, name: str, age: int):
        self.id = id
        self.name = name
        self.age = age
