如何检索与json中的名称对应的随机值

import json
import random

# 示例JSON数据
json_data = '''
{
  "name1": 123,
  "name2": "abc",
  "name3": [1, 2, 3],
  "name4": {
    "sub_name": "xyz",
    "sub_value": 456
  }
}
'''

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

# 遍历JSON数据并检索随机值
def retrieve_random_value(json_data, name):
    if isinstance(json_data, dict):
        for key, value in json_data.items():
            if key == name:
                if isinstance(value, list):
                    return random.choice(value)
                else:
                    return value
            elif isinstance(value, (dict, list)):
                result = retrieve_random_value(value, name)
                if result is not None:
                    return result
    elif isinstance(json_data, list):
        for item in json_data:
            result = retrieve_random_value(item, name)
            if result is not None:
                return result

# 检索名称为"name3"的随机值
random_value = retrieve_random_value(data, "name3")
print(random_value)
