Executing output of python from loop in bash

I wrote a bash that has python command included in loop: (part of script)

#!/bin/bash

ARG=( $(echo "${@:3}"))
for (( i=1; i<=$#-3; i++ ))
do
python -c "print('<Command with variables>' * 1)"
done

When I run it, depends on number of my args for example I have this output:

nohup command-a &
nohup command-b &
nohup command-c &

How do I execute the output lines from bash immediately?

Can I tell python command to run them in each iteration? How?

Thank you

You can achieve that by executing the python code in a sub-shell and evaluating the content of that shell afterwards.

eval $(python -c ...)

$() returns a string you can evaluate with eval

You are asking two questions. I can only answer the first one:

If you want to run commands coming to the standard output, just redirect them to bash:

python -c 'print "ls"' | bash
