Conversion to and from Jupyter notebooks

Python -> Notebook

One can use jupytext

jupytext --to=ipynb --output=path_to_nb.ipynb

The Python file should follow the conventions of the light format for appropriate rendering.

Notebook -> Python

You can add meta-data to your notebook, making it auto convert to a Python-file at saving (using JupyterLab). This can be achieved by pressing ctrl+shift+c and choose Pair notebook with light script.

You could also directly modify the notebook metadata with:

{
# Other options
#....
"jupytext": {
    "formats": "ipynb,py:light"
}
}

One can also use pre-commit hooks to automatically sync notebooks with a corresponding file, see here
