Tidying up Python

[Christoph Kukulies]

Thanks, Nils,

for clarifying. I understand.

So it looks like that for now. I did that port install py-jupyter. After that I did

sudo port select --set ipython py313-ipython

But I still get:

$ which python3
/opt/local/bin/python3
$ python3

>>> quit()
$ which python
/opt/local/bin/python
$ python

>>> quit()
$
$ echo $PATH
