Tidying up Python

[Christoph Kukulies]

Thanks to all,

selecting python313 now worked. Actually what set the ball rolling was the fact that my jupyter is defunct.

It began, when jupyter under conda/anaconda3, had an outdated sympy package. It ended up in removing anaconda/conda totally from my system.
After that jupyter didn't work any longer:

$ jupyter notebook
usage: jupyter [-h] [--version] [--config-dir] [--data-dir] [--runtime-dir] [--paths] [--json] [--debug] [subcommand]

Jupyter: Interactive Computing

positional arguments:
  subcommand     the subcommand to launch

options:
  -h, --help     show this help message and exit
  --version      show the versions of core jupyter packages and exit
  --config-dir   show Jupyter config dir
  --data-dir     show Jupyter data dir
  --runtime-dir  show Jupyter runtime dir
  --paths        show all Jupyter paths. Add --json for machine-readable format.
  --json         output paths as machine-readable json
  --debug        output debug information about paths

Available subcommands: 3.13 console dejavu events execute kernel kernelspec lab-3.13 labextension-3.13 labhub-3.13 migrate
nbconvert notebook-3.13 run server troubleshoot trust

Jupyter command `jupyter-notebook` not found.

After the python313 episode the above jupyter disfunctionality persists.

An attempt to install jupyter now under python313 shows that there are 3.11 dependencies:

pip3 install jupyter
Requirement already satisfied: jupyter in /usr/local/lib/python3.11/site-packages (1.1.1)

and lots more of references to python 3.11

If "port select python" currently allows versions of python 3.x to be selected, we may want to change that.
