Great question, David.

I’ve open the Jupyter Notebook that I’ve created with PyCharm and it looks the same as it would be created in JupyterLab. This kinda makes sense, because PyCharms uses the Jupyter server to execute the cells in a notebook.

What surprised me is that PyCharm Notebooks have #%% sign on top, but the sign is not visible when I opened the notebook in JupyterLab.
