Python multi-threaded login remote Linux execute command

What is a process?

Process, which is a running state of the program.

What is a thread?

Why Use Threads?

Thread, which is the "execution unit" inside the process .

A process can contain multiple threads, and each thread can execute different code.

That is, with multiple threads, one process can perform multiple functions at the same time!

Prerequisite Installation Sshpass
