Importing files modulenotfounderror

Question

I have looked on multiple stackoverflow post but cannot find the answer. I have the following file structure i am also doing this in a django project

crypto_api_site
    bitvavo_api
        bitvavowallet.py
        data.py
    main
        views.py

Where data.py imports bitvavowallet.py and views.py imports data.py . But when executing python manage.py runserver I keep getting the error ModuleNotFoundError: No module named 'bitvavowallet'

my import in views.py looks like this sys.path.append('crypto_api_site/bitvavo_api/')

from bitvavo_api import data

and my import in data.py looks like this

import bitvavowallet

I also added __init__.py in the directories Thanks in advance for any help
