It's confusing, but this isn't a bug. As you mention, pathlib.Path.path isn't documented, and there's a reason for that. In Python 3.5, pathlib is still technically a provisional API, which you can see mentioned in the doc page. That means that the API can change in backward incompatible ways, which you've seen here.
The .path attribute was an attempt at making pathlib objects more compatible with other APIs that require paths-as-strings, but it really didn't work very well. There was extensive discussion on various mailing lists about how to go forward and the outcome of that was PEP 519: https://www.python.org/dev/peps/pep-0519/ So in Python 3.6 there will be a blessed protocol for interoperability between pathlib paths and str paths, but this is not backported to 3.5. PEP 519 also says: """ The path attribute will be removed as this PEP makes it redundant (it has not been included in any released version of Python and so is not a backwards-compatibility concern). """ Technically true, but I suspect because Matthias uploads inter-release snapshots, you got caught in the small window where the attribute existed between the 3.5.1 and 3.5.2 releases, and before it got removed upstream. Until 3.6 is available, str(path) is your best workaround. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1604147 Title: pathlib.Path.path attribute has disappeared To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/python3.5/+bug/1604147/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
