1，关于EdgeX Python
EdgeX 有 golang 的和 c的 SDK，但是目前没有 python 的服务。
需要自己折腾。还好万能 的GITHUB 上面有人已经研究了。

2，项目说明
特别简单，一个python 脚本。
egfCreateEndpoint-07.py
运行的时候直接
python egfCreateEndpoint-07.py -ip xx.xx.xx.xx -version edinburgh脚本就支持两个 版本 一个 edinburgh ，一个 delhi
使用python 的requests 和 requests_toolbelt 库直接进行接口访问：

3，总结
开源边缘计算框架 EdgeX Foundry ，服务启动之后，python的程序也可以进行注册。
注册之后就可以提供服务了。
