python: get directory two levels up

Question

Ok...I dont know where module x is, but I know that I need to get the path to the directory two levels up.

So, is there a more elegant way to do:

Answer 1

More cross-platform implementation will be:

import pathlib
two_up = (pathlib.Path(__file__) / ".." / "..").resolve()

Using parent is not supported on Windows. Also need to add .resolve(), to:

Make the path absolute, resolving all symlinks on the way and also normalizing it (for example turning slashes into backslashes under Windows)
