"Hot: Pathlib, Not: String Paths"
summary
Live demo replaces os.path strings with pathlib Path objects showing concrete methods and results: creating paths (Path, PurePath, platform-specific Windows/Posix classes), joining with '/', Path objects are hashable so they work as set keys, mkdir(parents=True, exist_ok=True) creates deep trees, touch/write_text/read_text create and read files, glob/rglob and new walk return iterative results, resolve vs absolute with resolve(..., strict=True) raises if target missing, unlink/rmdir/replace delete, and a cleanup script runs and successfully removes the created tree.
