You thought wrong.
os.path.join just joins what you tell it to, it doesn't normalise the
path. If you want to normalise, call os.path.normpath:
As for why, it's because joining and normalising are two different
operations that you may wish to keep separate, so they require two
BTW, Windows accepts / as well as \ as a path separator. You will have
far fewer headaches if you use that.
