Apologies for responding to something that's not the point of your
post, but I see this as a job for map, rather than a list comp:

def norm_path(*parts):
    """ Returns the normalized, absolute, expanded and joined path,
assembled of all parts. """
    path = os.path.join(*map(str,parts))
    return os.path.abspath(os.path.expanduser(path))

(or completely onelinered, since you don't seem to mind longish lines).
