Walk Directory Trees Safely with Python pathlib Path.walk

Python 3.12 added pathlib.Path.walk(), bringing directory-tree traversal directly to Path objects. It fills the same broad role as os.walk(), but keeping traversal and path manipulation in pathlib can make filesystem code easier to read. Walking a tree is deceptively simple, though. Production code needs to decide which subtrees to enter, what to do with unreadable directories, whether symbolic links should be followed, and whether the filesystem may change during traversal.

Copy and Move Paths with pathlib in Python 3.14

Python 3.14 adds high-level copy and move operations directly to pathlib.Path. Path.copy(), Path.copy_into(), Path.move(), and Path.move_into() make many filesystem workflows easier to express without switching between pathlib, shutil, and os for basic operations. The convenience is useful, but filesystem mutations still need explicit policy. Overwrites, symbolic links, metadata, cross-filesystem moves, partial failure, and concurrent changes can all affect correctness. The four new operations Use copy() when the destination path itself is known:
