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.
Stéphane

In the documentation of os.system [1], there is this paragraph, where we suggest to use subprocess instead of os.system. """ The subprocess module provides more powerful facilities for spawning new processes and retrieving their results; using that module is preferable to using this function. See the Replacing Older Functions with the subprocess Module section in the subprocess documentation for some helpful recipes. """ But I have found some references (between 15 and 23 (if we include setup.py)) of os.system.
Do we need to keep the code like that or could we start to use subprocess for these "references" because it is preferable? If you think we could move to subprocess, I would like to open an issue and try to fix it. 1. Add the 'deprecated' directive in the doc 2. Use subprocess for these references What is your opinion?
