I am packaging my first python project, and I have two files with helper functions, comments.py and score.py stored in the subdirectory.

YT_Sentiments/
└── src/
    ├── YT_Sentiments/
    │   ├── helpers/
    │   │   ├── __init__.py
    │   │   ├── score.py
    │   │   └── comments.py
    │   ├── __init__.py
    │   └── main.py
    ├── LICENSE
    ├── pyproject.toml
    ├── README.md
    └── setup.py

in my main.py I import the two files

    from helpers import score.py
    from helpers import comments.py

When I build and install it locally, I get the error:

    File "C:UsersAppDataLocalProgramsPythonPython311Libsite-packagesYT_Sentimentsmain.py", line  
    1, in <module>
    from helpers import score
    ModuleNotFoundError: No module named 'helpers'

I have followed atleast 4 tutorials on packaging and implemented what I thought would solve my problem (setup.py and pyproject.toml)

setup.py

    from setuptools import find_packages, setup

    with open("README.md") as f:
        long_description = f.read()

    setup(name = "YT_Sentiments",
          version = "0.0.4",
          description = "analyze comments from any youtube video!",
          package_dir = {"":"YT_Sentiments"},
          packages = find_packages(where="YT_Sentiments"),
          long_description=long_description,
          long_description_content_type="text/markdown",
          license = "MIT",
