如何遍历json数据并获取特定键值

def traverse_json(data, target_key):
    if isinstance(data, dict):
        for key, value in data.items():
            if key == target_key:
                print(f"找到目标键值对：{key}: {value}")
            if isinstance(value, (dict, list)):
                traverse_json(value, target_key)
    elif isinstance(data, list):
        for item in data:
            traverse_json(item, target_key)

{
  "name": "John",
  "age": 30,
  "address": {
    "street": "123 Main St",
    "city": "New York"
  },
  "pets": [
    {
      "name": "Fluffy",
      "type": "cat"
    },
    {
      "name": "Spot",
      "type": "dog"
    }
  ]
}

data = {
  "name": "John",
  "age": 30,
  "address": {
    "street": "123 Main St",
    "city": "New York"
  },
  "pets": [
    {
      "name": "Fluffy",
      "type": "cat"
    },
    {
      "name": "Spot",
      "type": "dog"
    }
  ]
}

traverse_json(data, "name")

找到目标键值对：name: John
找到目标键值对：name: Fluffy
找到目标键值对：name: Spot
