Most people don't use pathlib, and that's kind of sad, since it tries to
mitigate the kinds of questions you just asked. Kudos for trying.

For your example, when you define inp as a string, it needs to be a raw
string because otherwise Python will interpret the backslash sequences.
\t means tab, which is why the the results look mangled.

inp = "c:\test\drive\this"

If you're going to use pathlib, then may as well use the / operator for
joining,
