I want to get the first 6 lines of ps output. For this I use:
========================================================================
from subprocess import check_output

ps_command = ('ps', '-eo', 'user,pid,pcpu,pmem,stat,start,time,cmd', '--sort')
message = '\n'.join(check_output(ps_command + ('-%cpu',)).decode("utf-8").splitlines()[0:6])
========================================================================

It works, but does not look very efficient. Is there a better way to
do this?
