如何根据值从JSON文件中获取完整的字典数据

import json

def find_dict_by_value(json_data, target_value):
    for key, value in json_data.items():
        if value == target_value:
            return {key: value}
        elif isinstance(value, dict):
            result = find_dict_by_value(value, target_value)
            if result is not None:
                result[key] = value
                return result
    return None

# 读取JSON文件
with open('data.json', 'r') as file:
    json_content = file.read()

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

# 根据值获取完整的字典数据
target_value = '目标值'
result = find_dict_by_value(json_data, target_value)

if result is not None:
    print("找到了目标值所在的字典数据：")
    print(result)
else:
    print("未找到目标值所在的字典数据。")
