Re: [Python-3000] os.popen versus subprocess.Popen

If any user input is involved, there will almost certainly be security problems. If not, it will frequently break anyway. As Guido pointed out, you can specify shell=True to get this latter behavior. But if you do this, you often sacrifice correctness and/or security. It's not a good ha
