What does sys.path.append("..") do?

Question

I bumped into this statement in a Python script: sys.path.append("..") I did some research, but I could not find what it does.

I know sys.path.append() function appends a path at the end of the PYTHONPATH list. But what does ".." stand for?

Needless to say, this Python scripts does not work if I comment the line.

It adds the .. to the paths that Python searches for imports, so you can import things from .. (which is the parent of the current directory) . – Oto

Well, that is clear that it looks like it refers to parent directory, and it has been my first thought. Though, when I change sys.path.append("..") to sys.path.append(absolute-path-to-parent-directory), it does not work and throw a ModuleNotFoundError when I try to load a module from that directory... – Staton

Answer 1

".." is a way of saying/referencing the parent of the current working directory.
