os module: reject bytes-like strings for paths, only accept the exact bytes type #98393

New issue
New issue

Description

In Python 3.6, the support for "bytes-like" paths was deprecated (commit d73c318): see issue #70987 for the rationale.

I propose to remove the support for bytes-like paths in Python 3.12. The feature was deprecated in 6 Python releases (PEP 387 is respected). In practice, the two most common "bytes-like" types are: bytearray and memoryview.
