I guess, you didn't get his point. He seems to be aware that os.path.join
creates a path from _multiple_ strings by joining them with the correct
separator used by the underlying platform.
But he was asking why one would invoke os.path.join on a _single_ string, as
you did in your example. I'm wondering about this, too. It doesn't make
sense to me. os.path.join doesn't convert existing separators to the
platform-specific ones. And even if it would, sys.argv[0] already contains
a correct path, so there is nothing that needs conversion. So why use it
with a _single_ argument? I'd appreciate an example, illustrating the use
of this ;)
