Import module from parent directory python

Question

Please don't delete this. this is so simple but I'm banging my head making this work for last two hours.

As displayed. I want to import python file module_dir into module_sub_dir.py, but its giving erros. all init.py are empty.

from .. import module_dir

This doesn't work either as it gives erro

ImportError: attempted relative import with no known parent package

How are you running the script? Are you running python sub_dir/module_sub_dir.py? — mikicz

Starting python 2.5 you can import from parent using three dots: from ... import module_dir — Pietro D'Antuono

@mikicz I have opened 'dir' folder (main/root folder) in VS code. — yf879

If you have dir folder open, then you shall import directly from the current folder. Then it is: from . import module_dir. Also, the folder containing module_dir.py must contain an __init__.py as well to be "recognized" as a python package — Pietro D'Antuono

Add sys.path.append("..") to the very beginning then importlib will be able to reach the file in parent directories of CWD. But I recommend you not to use such ugly solution in your projects.

Yeah, I'm trying to avoid that, I see that people making it work without sys.path but for some reason this is not working for me.

Another way to do something similar would be to define the environment variable PYTHONPATH to point to dir

Update as I have figured out the issue myslef.

So the issue is how VS Code runs .py file individually as oppose to running entire package like Pycharm. It works in Pycharm. To make it work in VS Code sys.import.path('..') works.
