How do I run os.system in multi-thread mode?

I have a function where I am invoking multiple python scripts with each being invoked with os.system call.

def fun():
    os.system('python '+_path+'\\abc.py '+_arg1+' '+_arg2)
    os.system('python '+_path+'\\xyz.py '+_arg1+' '+_arg2)
    os.system('python '+_path+'\\123.py '+_arg1+' '+_arg2)
    os.system('python '+_path+'\\xxx.py '+_arg1+' '+_arg2)

I want these os.system calls to run in thread mode. Currently it is in sequential mode. Is there any way it can be made in multi-threaded mode?

What I have tried:

function fun() is running in multi-threading mode by getting called from another function. But I did not find a way to make os.system multi-threaded.

Thanks @CPallini. I used it and feel I am getting some success. I am stuck at how do I figure out if subprocess is still running or not? I noticed Subprocess always returns 'None' as returncode even though it has finished. Any idea?
