python-3.x import modules Python

I just started working with I'm trying to debug I'm having trouble with I've been struggling with this for a few days now and could really use some help. I'm experiencing an `ImportError` when trying to import a custom module in my Python 3.10 project. I have the following directory structure: ``` my_project/ ├── main.py └── my_package/ ├── __init__.py ├── module_a.py └── module_b.py ``` In `main.py`, I have the following import statements: ```python from my_package.module_a import some_function ``` However, when I run `main.py`, I receive the behavior: ``` ImportError: want to import name 'some_function' from 'my_package.module_a' ``` I double-checked that `some_function` is defined in `module_a.py` and there are no circular imports. Here's a snippet of `module_a.py`: ```python def some_function(): return 'Hello from module_a!' ``` I've tried adding `__all__ = ['some_function']` at the end of `module_a.py`, but the behavior continues. I also confirmed that the `__init__.py` file is present and is not empty. What could be causing this scenario? I suspect it might be related to the way Python resolves module paths. Any help would be appreciated! I'm working in a Ubuntu 20.04 environment. Thanks, I really appreciate it! Am I approaching this the right way?
