The path provides an optional sequence of directory names terminated by the final file name including the filename extension.

Thanks for reading! Here's how they're used: All of these methods return strings which can be passed to pathlib.Path(str) to create a Path object, which is similar to a string but has different functionality: In the file-renamer code, here's how they are implemented: Here, when user_input is cd .. , a new_path string is created from current_directory.parent, and is turned back into a Path object with current_directory = pathlib.Path(new_path).
