I would like to answer with a counter-question: Why do you want to do
this? What is the reason to use ls -l if you could also be using
os.listdir() or os.scandir()?

There are some reasons against screenscraping `ls` (locale-specifities
and environment variable dependencies of ls) and using shell=True (with
shells being huge complex beasts which may have unexpected security
issues, see Shellshock), so I’m not sure why you would want to do that.
