Python automation development from shallow into deep-advanced (process)

Today's job involves a process, then use the job to illustrate the use of the process:

Here we define 2 functions Getparamikocmd and Batchcmd, which are used to send SSH commands to the remote server in bulk and return the execution results.

Execute batchcmd for some user interaction and parameter acquisition (here is a set of server grouping information), the loop initiation process executes the SSH command in bulk, each process calls the Getparamikocmd function for SSH command execution.

Processes are independent of each other, and data does not share with each other, so that it can accomplish its tasks independently without affecting each other.
