I am still not understanding.

Is your problem that you don't want to wait for the script to be done
on machine A before you go to machine B?

fork a separate process for each machine.

You could even do this in, for instance, a bash shell.
Given a script called myscript.py that takes a machine name as an argument=
.

for machine in `cat list_of_machines`
        do
	python --machine $machine myscript.py &
	done
	=

if you need to do this inside python see
os.fork https://docs.python.org/3.4/library/os.html
and make sure you read about the problems with ssl if
you care.  https://docs.python.org/3.4/library/ssl.html#module-ssl

Most people don't need any more 'at the same time' than this.
Do you?
