I can make these changes. Would probably add a .exists method to PurePath, 
using the _normal_accessor.stats staticmethod, then call that in __contains__

[issue33301] Add __contains__ to pathlib

2018-06-19 Thread Andrew Berger 


Andrew Berger  added the comment:

I think the idea is that either a subdir or file could be valid inputs. 

So `Path('/usr/bar') in Path('/etc/foo')` return True if 
`Path('/etc/foo/usr/bar')` is either a dir or file.

As for PurePath, I did overlook that accessing an inode via a call to stat 
would be considered filesystem IO. So putting that method in Path (if this 
turns out to be a good idea) is the better option. Thanks
