Nor is the value returned by the string 'split' function quite what
you describe.
>>> p.split(os.sep)
['', 'tmp', 'a', 'b', 'c', 'd']
>>> os.path.split(p)
('/tmp/a/b/c', 'd')

>>> import os
>>> p = ["/tmp", "a", "b", "c", "d"]
>>> os.path.join(*p)
'/tmp/a/b/c/d'

It also isn't 'os.path.join'.
>>> p = ["/tmp", "a", "b/", "c/", "d"]
>>> os.sep.join(p)
'/tmp/a/b//c//d'
>>> os.path.join(*p)
'/tmp/a/b/c/d'
