本文操作示例介绍如何使用Alibaba Cloud SDK for Python创建和删除专有网络VPC（Virtual Private Cloud）与交换机vSwitch。
在使用Alibaba Cloud SDK for Python前，您需要完成以下准备工作：
您需要一个阿里云账号和访问密钥（AccessKey）。 请在阿里云控制台中的
AccessKey管理页面
上创建和查看您的AccessKey。
确保您已经安装了Alibaba Cloud SDK for Python，请参见
aliyun-python-sdk-vpc 3.0.25
。
下载阿里云专有网络Python SDK场景示例的
VPC Python Example库
。
setup.py
所在的目录，执行以下命令，完成环境初始化配置。
python setup.py install
在下载的SDK目录中，打开
aliyun-openapi-python-sdk-examples\sdk_examples\examples\vpc
文件夹。
使用代码编辑工具打开
vpc_quick_start.py
文件，根据实际情况配置相关参数，保存退出。
完整代码示例如下：
