pathlib offers a set of classes to handle filesystem paths. It offers the
following advantages over using string objects:
* No more cumbersome use of os and os.path functions. Everything can be
done easily through operators, attribute accesses, and method calls.
* Embodies the semantics of different path types. For example, comparing
Windows paths ignores casing.
* Well-defined semantics, eliminating any warts or ambiguities (forward vs.
backward slashes, etc.).
It's part of Python 3.4+ standard library.
