[Tutor] Question on os.popen

[SM]

Hi Alan,
Thanks for your reply.
My answer to why I am using os.popen could be a lame one - I have used it
extensively in various places before and it has been working well and so
was hung up on using it. Now I replaced it by subprocess.check_output with
appropriate parameters and it seems to be working. Does that mean this is
one of the limitations of os.popen? I am not sure.
Sorry for not giving details on the OS and python version I am using:
Ubuntu and Python3.
Thanks,
SM
