What is the absolute import and relative import for this kind of directory structure?

Question

I have a directory structure like this,

Assignments

├── Assignment1

│ ├── Assignment-1.pdf

│ └── assignment1.py

└── Methods

├── init.py

├── primality.py

I want to import functions from the primality.py file into the assignment1.py file.

What is my relative and absolute import line for this dirctory structure?

I also tried using this, from ..Methods.primality import func

but it gives me an error,

ImportError: attempted relative import with no known parent package

Can anyone explain me what am I doing wrong here?

There are multiple assignments folders which contains assignment.py file and every assignment.py required different custom packages from the directory Methods. So, in assignment.py file, I import custom packages from the Methods directory with this line "from ..Methods.primality import func" but it resulted into the import error mentioned in the question. — Purvesh Patel, Jan 13 '23 at 22:22
Yes I asked how do you run this code - what is the command line (for one of the assignments) — Mr_and_Mrs_D, Jan 14 '23 at 14:26

You should add the missing __init__.py as in:

├── Assignment1

│       ├── Assignment-1.pdf

│       ├── __init__.py # this

│       └── assignment1.py

└── Methods

│       ├── __init__.py

│       ├── primality.py

then go to the Assignments folder and from there run:

$ python3 -m Assignment1.assignment1 # note no py

Then python sees the directory structure as a package structure and Methods/Assignment1 are packages (and you should rename them to methods/assignment1)
