I like os.system() and use it everyday. I prefer to write
os.system("grep ^Vm /proc/%s/status" % os.getpid()) than... much more
Python code to do the same thing, or subprocess.run("grep ^Vm
/proc/%s/status" % os.getpid(), shell=True):os.system() is shorter and only requires "import os" :-) I'm not using os.system() for "production ready" code, but when I develop, play with the REPL, etc. For production code, I would write a function which avoids spawning a new process, obviously. But well, shell commands are shorter and easier to write (for me, at least).
