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


The os module is by definition special.  It exposes libc and platform
APIs.  That there are Python modules that provide similar functionality,
often surpassing it and sometimes being built on top of it, is
intentional.  Random quotes from the Zen don't win arguments.  Although
practicality beats purity.  :P

os.system isn't going away.  That'd be unnecessarily disruptive.
