[New-bugs-announce] [issue34333] Path.with_suffix() raises TypeError when doing %-formatting

[Berker Peksag]

New submission from Berker Peksag <berker.peksag at gmail.com>:

import pathlib

path = pathlib.Path('TR')
with_suffix = path.with_suffix(('/', '.md'))

The snippet I shared above will raise:

    TypeError: not all arguments converted during string formatting

While we are relying on duck typing, I think this can be considered as a bug in this case.
