R. David Murray <rdmurray at bitdance.com> added the comment:

(D) in python 3, os.popen has been reimplemented using subprocess.Popen.
So the other mentions of os.popen should probably be replaced with mentions of subprocess.Popen.

Your (C) is close...the continued existence of os.popen in Python3 is, I think, a bit of a kludge (I wasn't around for the discussion), but a backward compatibility one.  I don't know if there is a plan to deprecate it, but I suspect not.  On the other hand I certainly wouldn't recommend using it, since it does an import inside the function, which can get one into trouble if one uses threads.
