path in py3K Re: r51624 - in python/trunk/Lib: genericpath.py macpath.py ntpath.py os2emxpath.py posixpath.py test/test_genericpath.py
In Py3K, is it still safe to assume that a list of paths will be (enough like) ordinary strings? I ask because of the various Path object discussions; it wasn't clear that a Path object should be a sequence of (normalized unicode?) characters (rather than path components), that the path would always be normalized or absolute, or even that it would implement the LE (or LT?) comparison operator. -jJ On 8/26/06, jack.diederich <python-checkins@python.org> wrote:

It is not my intention to adopt the Path module in Py3k. On 8/26/06, Jim Jewett <jimjjewett@gmail.com> wrote:
