http://stackoverflow.com/a/29880095/2097780 My favorite thing about Python is that it's so easy to be evil. ;) On Fri, May 1, 2015 at 2:30 PM, Christophe Bal wrote:

Hello.

In this post http://stackoverflow.com/questions/29850801/simple-subclassing-pathlib-path-..., I have noticed a problem with the following code.

from pathlib import Path

...

class PPath(Path): def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs)

test = PPath("dir", "test.txt")

This gives the following error message.

...

Traceback (most recent call last): File "/Users/projetmbc/test.py", line 14, in <module> test = PPath("dir", "test.txt") File "/anaconda/lib/python3.4/pathlib.py", line 907, in __new__ self = cls._from_parts(args, init=False) File "/anaconda/lib/python3.4/pathlib.py", line 589, in _from_parts drv, root, parts = self._parse_args(args) File "/anaconda/lib/python3.4/pathlib.py", line 582, in _parse_args return cls._flavour.parse_parts(parts)AttributeError: type object 'PPath' has no attribute '_flavour'

This breaks the sub-classing from Python point of view. In the post http://stackoverflow.com/questions/29850801/simple-subclassing-pathlib-path-..., I give a hack to sub-class Path but it's a bit Unpythonic.

It does sound like subclassing Path should be made easier.

Christophe, if you want to pursue this, you should open an issue for it on the Python bug tracker, bugs.python.org. Otherwise, it will likely be forgotten here. -- Ned Deily, nad@acm.org
