迭代json和构造python对象

import json

# 示例JSON数据
json_data = '''
{
  "name": "John",
  "age": 30,
  "city": "New York",
  "pets": [
    {
      "name": "Tom",
      "species": "cat"
    },
    {
      "name": "Jerry",
      "species": "mouse"
    }
  ]
}
'''

# 解析JSON数据为Python对象
data = json.loads(json_data)

# 迭代JSON对象
def iterate_json(data):
    if isinstance(data, dict):
        for key, value in data.items():
            print(key, value)
            iterate_json(value)
    elif isinstance(data, list):
        for item in data:
            iterate_json(item)
    else:
        print(data)

# 构造Python对象
class Person:
    def __init__(self, name, age, city, pets):
        self.name = name
        self.age = age
        self.city = city
        self.pets = pets

    def __str__(self):
        return f"Name: {self.name}, Age: {self.age}, City: {self.city}, Pets: {self.pets}"

# 构造Person对象
person = Person(data["name"], data["age"], data["city"], data["pets"])

# 输出结果
print("迭代JSON对象：")
iterate_json(data)
print("构造Python对象：")
print(person)
