省市区json转list

可以通过以下方式将省市区的JSON数据转换为列表：

import json

def json_to_list(data):
    result = []
    for item in data:
        province = item['name']
        cities = item['cities']
        for city in cities:
            city_name = city['name']
            districts = city['districts']
            district_names = [district['name'] for district in districts]
            result.append((province, city_name, district_names))
    return result

# 示例的省市区JSON数据
json_data = '''
[
    {
        "name": "北京市",
        "cities": [
            {
                "name": "北京市",

                "name": "上海市",
                "districts": [
                    {"name": "黄浦区"},
                    {"name": "徐汇区"},

'''

data = json.loads(json_data)
result_list = json_to_list(data)

# 输出结果
for item in result_list:
    province, city, districts = item
    print(province, city, districts)

上述代码将会输出：

北京市 北京市 ['东城区', '西城区', '朝阳区', '丰台区', '石景山区', '海淀区', '门头沟区', '房山区', '通州区', '顺义区', '昌平区', '大兴区', '怀柔区', '平谷区', '密云县',
