Simple Python Master Batch management tool

today did a very simple small project, feel the Paramiko module of the powerful, but also feel that their own Linux power not ~ ~

First, the demand

Second, simple requirements analysis and flow chart

With few requirements, I'll simply say:
1. Host groupings can be configured with file implementations (I use a dictionary to store data).
2. Login function is not done. Select a group to view the host name and IP address of the corresponding host in the group.
3. >>>CMD:DF (Input command from multiple threads (depending on the number of hosts in the group)
Output:
-------------h1------------
...... (The data returned by the command)
-------------h2------------
......
>>>put test.yy (local file) filename (the local test.yy file is uploaded to the/root directory of the remote host)
4. Can be written in the configuration file. Includes remote host: hostname IP user name password port

Flow chart

III. directory structure and source code

Directory structure:
