[New-bugs-announce] [issue35498] Parents objects in pathlib.Path don't support slices as __getitem__ arguments

[Joshua Cannon]

New submission from Joshua Cannon <joshdcannon at gmail.com>:

I would expect the following to work:
```
>>> import pathlib
>>> pathlib.Path.cwd().parents[0:1]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "...\Python36\lib\pathlib.py", line 593, in __getitem__
    if idx < 0 or idx >= len(self):
TypeError: '<' not supported between instances of 'slice' and 'int'
```

Since pathlib documents `parents` as a sequence-type, and slicing a sequence is pretty standard behavior.
