absolute imports between folders

[mikisDW]

Hello,

I'm working on a tkinter gui, and I keep having issues with imports.
I've spent quite some time reading about imports, but I guess it still hasn't sunk in.

My project folder is setup like so:
Project/
|-- gui/
| |-- my_gui.py
|-- custom_functions/
| |-- __init__.py
| |-- module1.py
| |-- module2.py

my_gui.py uses a function in module2.py (my_function), which in turn imports a function from module1.py (parseVariable).
While developping module2, I imported like this

from module1 import parseVariable

This works fine in module2, but would cause import errors in my_gui.py.
So what I did in my_gui.py is to add the folder "custom_functions" to my path.

scriptLoc = os.path.dirname(os.path.realpath(__file__))
# add parent folder to path
sys.path.append(str(Path(scriptLoc).parent))
# in this parent folder is a folder named custom_functions, add that too
sys.path.append(os.path.join(scriptLoc, 'custom_functions\\'))
from custom_functions.module2 import my_function

...And I converted the import in module2 to

from custom_functions.module1 import parseVariable

That works great, except when I now run module2 as my main script (if __name__ == '__main__')
Then it would cause an import error again.

So currently, when working/debugging in module2.py, i revert back to the original (from module1 import parseVariable) and after debugging I switch it back to from custom_functions.module1 import parseVariable

I'm sure there is a way that this import would work in both scenario's, but I can't figure it out

Any help?

Thanks,
Mikis

sorry... it hit me that I should have typed

sys.path.append(os.path.join(str(Path(scriptLoc).parent), 'custom_functions\\'))[\python]

Now it works.
But I still feel this is not best practice, right?
