I think I’ve left a note about this before - sorry.
JupyterLab works with python, but it is horrendously slow compared with Notebook - there are frequent long periods (10+ seconds) when there is no keyboard response, and I consider it unusable.
Python is simply not visible in Jupyter Notebook.
Below are the jupyter notebook and lab logs with slashes removed
I have pip uninstalled and reinstalled jupyter, no effect.
My other computers all work with Python in jupyter notebook, jusat this one does not, and it is my main new computer. Windows 11, Python 3.12, Firefox default browser. A few firefox add-onss but only the same ones as used on the other computers
