python api 调用虚拟私有云子网管理

from HwUser import HwUser
import json
import time

'''
    在云服务器的/root/huawei 目录下编写 create_subnet.py 文件， 并导入赛项提供的HwUser.py 文件获取授权。编写 Python 代码，参考官方相关的API调用文档，创建华为云的虚拟私有云子网，具体要求为
    
    （1）使用虚拟私有云名称获取其 ID（不允许直接填写虚拟私有云 ID）；

    （2）虚拟私有云子网名称：chinaskills_subnet；

    （3）虚拟私有云子网网段：192.168.100.0/24；

    （4）虚拟私有云子网网关：192.168.100.1；

    （5）虚拟私有云子网可用区域：cn-north-4a；

    （6）如果虚拟私有云子网已经存在，代码中需要先删除；

    （7）使用其源码的 get 方法输出此虚拟私有云子网的详细信息（状态要求为 ACTIVE）。
