I have a Jupyter Notebook file in which I’m trying to import compiled C extensions and Python files from a `src` folder located within the same directory. I can successfully import the module using `import src.module_name`, but I want to achieve dynamic imports with just `import module_name`. I have also configured my `pyproject.toml` file to set the `python_paths` option but it doesn’t really work. Here’s my directory structure:
```auto
project_folder/
├── my_notebook.ipynb
├── src/
│ └── module_name.c
└── pyproject.toml
```
In my Jupyter Notebook
**Working Solution:**
```python
import src.module_name
# Calculate lengths and elements for the range from 1 to 15 using Cython
sample_range, lengths, elements = src.module_name.calculate_lengths_cython(1, 15)
```
**Not Working Solution:**
```python
import module_name
# Calculate lengths and elements for the range from 1 to 15 using Cython
sample_range, lengths, elements = module_name.calculate_lengths_cython(1, 15)
```
And here’s my `pyproject.toml` file:
```toml
# pyproject.toml
[tool.pytest.ini_options]
python_paths = ["src"]
```
Note: The `module_name.c` file contains C code that has been compiled into a C extension.
Is there a way to achieve dynamic imports without explicitly including the `src` folder in the import statement?

I deleted the other one, I didn’t think posting on 2 different forums would be problematic as I wanted to reach as many informed people as possible. But I understand that it is best to have a single post addressing the question.

If writing a `pyproject.toml`, it’s not really going to have any effect for python itself until it’s installed, e.g. with `pip install -e .`, and the compiling/cythonizing step actually occurs. Then `import module_name` should work.

Thank you that works
