python run nmon instructions

The first step:
installation: paramiko
window installation method: pip install paramiko

Reference: http://www.jb51.net/article/97655.htm
Step 2:
The following code contains everything under sending commands and downloading a single file and directory file; the
disadvantage is that there is no multi-process execution;
