尝试根据用户在下拉菜单中的选择从json文件中提取输出

import json

    with open(file_path, 'r') as file:
        data = json.load(file)
    return data

# 根据用户选择提取数据

        for key in item:
            value = value.get(key)
            if value is None:
                break
        extracted_data.append(value)
    return extracted_data

# 输出提取的数据
def output_data(data):
    for item in data:
        print(item)

# 用户选择
user_selection = [
    ['field1', 'subfield1'],
    ['field2']
]

# JSON文件路径
json_file_path = 'data.json'

# 加载JSON文件
json_data = load_json_file(json_file_path)

# 根据用户选择提取数据
extracted_data = extract_data(json_data, user_selection)

# 输出提取的数据
output_data(extracted_data)
