python: how to pass output of system commands to variable


I'm trying to write a python script that will use the current user's name when interacting. Ex: when started, it should say "hello daweefolk" when I am logged in.
I've tried
Code:
username=os.system("echo $USER")
but the variable remains empty.
What is the correct code?

You can try os.environ, e.g.
Code:
username = os.environ.get("USER")
