🔒 Issues importing module

[junior bay]

Hi there. I'm having some issues importing a function from another python file I have written. Does anyone know why?

Visual studio doesn't complain about being unable to find the folder and file, but when i run the python file, it complains.

ModuleNotFoundError: No module named 'graphs'

• Ask your Python question, not if you can ask or if there's an expert who can help.
• Show a code sample as text (rather than a screenshot) and the error message, if you've got one.
• Explain what you expect to happen and what actually happens.

:warning: Do not pip install anything that isn't related to your question, especially if asked to over DMs.

Which file are you running?

[junior bay]

this file is bottom_up_critical_path.py

Add a .. In front of grpahs?

[junior bay]

ImportError: attempted relative import with no known parent package

i tried it and it said that

[winged spoke]

One dot? :-p

[junior bay]

Import ".graphs.dfs_topological_sort" could not be resolved

[wild stream]

The place where the script is located, it can’t “see” the graphs folder

[junior bay]

how do i fix that?

im trying to organise these files so i didnt really wanna lump hundreds into the same directory

[wild stream]

How are you running the file from within VS Code?

[junior bay]

just running py .\graph_dp\bottom_up_critical_path.py from the root directory of my project
