[Python-Dev] "Deprecation" of os.system in favor of subprocess?


Hi all,

After your feedback, I have my answer.

I understand the your points of view and I don't want to change any part
of code for os.system and subprocess, I don't want to deprecate
os.system in favor of subprocess. I just wanted to know your opinion
about this point.

+1 to use os.system when we only need a call without portability, just a
quick code.

+1 for subprocess for the portability.

Thank you so much for your patience/time and your explanations.
