content of app/calculations.py:

def add(num1: int, num2: int=2) -> int:
    return num1 + num2

content of tests/test_calculations.py:

from app.calculations import add

def test_add():
    print("testing function")
    assert add(3, 4) == 7

test_add()

When I try ton run python3 tests/test_calculations.py I get ModuleNotFoundError: No module named 'app' this error, however pytest runs without any problem.

From what I understand import in tests/test_calculations.py should look like this:

from ..app.calculations import add

# instead of:
# from app.calculations import add

I'm leaving tests/ directory and now I should have access to app package, but this time upon running python3 tests/test_calculations.py I get this error ImportError: attempted relative import with no known parent package and pytest throws this one: ValueError: attempted relative import beyond top-level package

Lastly VSCode has no problem with recognizing/reading both of these methods and doesn't show anything like for example Import ".app.calculations" could not be resolved Pylance. Edit: Just to be precise nothing runs when I hit play button in VSCode I'm talking only about Pylance

Hi all,

I was wondering if anyone had encountered this type of issue before. I am trying to import a module from a package I created. The package is in the same directory as my main.py file, but python is unable to use files in that directory I am using to initialize it's objects.

My structure is:

top level/
        main.py
        pckgfolder/
                __init__.py
                mymodule.py
                init.txt

ie, in main.py i have:

from pckgfolder import mymodule
myobject = mymodule.myClass()

and then within mymodule.py I have

class myClass:
        def __init__(self):
        with open('init.txt', 'r'):
        #load default data

When I try to do this I get:

FileNotFoundError: [Errno 2] No such file or directory: 'init.txt'

Since python cannot see the file I guessed that we need to add the directory with the module to the path, however I checked this is and it is in sys.path at runtime, so the file should be visible.

I added some print statements to __init__.py and found that when it is run the working directory is the top level, so I assume that is why the file is not visible, but do not know what to do about this (I do not wish to try things like changing the working directory during the run). When I was testing the module itself I did so from inside the directory and it worked fine, so I am quite lost here.

Hey Guys,

I get a weird ModuleNotFoundError in one of my projects and i do not really understand why. So here is my Folder Structure:

Project\

| main.py

| packageabc\

| | __init__.py

| | abc.py

| | packagexyz\

| | | xyz.py

In every .py file is an abc/xyz or main class. Now the interesting part. Inside the abc.py I do an import like this:

from packagexyz.xyz import xyz

This works perfectly fine!

Inside the main.py I do an import like this:

from packageabc.abcimport abc

Now I get an ModuleNotFoundError. Error Code looks like this:

from packagexyz.xyz import xyz ModuleNotFoundError: no module named packagexyz.

So the import in the abc.py File that works perfectly when tested inside the file does not work if the abc.py file is imported. So why is that?
