R. David Murray added the comment: Both the replace and rename functions will remain in the API, as they mirror the os module, not the os itself. I agree that the naming is unfortunate, but it has the weight of history behind it, so we are stuck with it. Issue 24229 rejected adding a copy method. Having replace and rename return a value strikes me as a good idea. Please open a separate issue with that enhancement proposal, and nosy 'pitrou', who is the author of the pathlib module. ---------- nosy: +r.david.murray resolution: -> rejected stage: -> resolved status: open -> closed _______________________________________ Python tracker <report@bugs.python.org> <http://bugs.python.org/issue31154> _______________________________________
