[issue43213] Shortcut for checking if PurePath object contains str
Tomas Gustavsson added the comment: Sorry Serhiy, missed your answer there. I understand your point. I guess I'll have to look for other things to help with :) Thank you for the answer. Guess this can be closed then.

Tomas Gustavsson added the comment: Okay, maybe a bad example. But let's say I want to find all folders and files but filter out those which contains .git,.svn in the paths. Anyhow, I believe this minor feature would make such use cases (and other) more clean and intuitive. I am lazy and I like when things work without me having to write more lines or characters then I need.

[issue43213] Shortcut for checking if PurePath object contains str
New submission from Tomas Gustavsson :
While using pathlib I realised there are situations where I easily want to
check if part of a returned path object contains a particular given path (as a
string).
Today the following will give an error:
...
path = PosixPath('/usr/share/doc/')
if 'share' in path:
print('Do something')
The patch will make the example above work and will open up for a simple
shortcut.
This is my first attempt to contribute, all opinions are very welcome.
I have also pushed the commit to my own branch
https://github.com/tomplast/cpython/tree/implement-path-contains.
