- Issue #21539: Add a *exists_ok* argument to `Pathlib.mkdir()` to mimic
`mkdir -p` and `os.makedirs()` functionality. When true, ignore
FileExistsErrors. Patch by Berker Peksag.
(With minor cleanups, additional tests, doc tweaks, etc. by Barry)
Also:
* Remove some unused imports in test_pathlib.py reported by pyflakes.
