Tidying up Python

[Christoph Kukulies]

I don't know how all these python versions got installed. They all may have come over the years
and I didn't do anything special to keep them.

$ port rdependents
The following ports are dependent on opencascade:
  kicad
$ sudo port reclaim
Password:
--->  Checking for unnecessary unrequested ports
Found no unrequested ports without requested dependents.
--->  Checking for inactive ports
Found no inactive ports.
--->  Building list of distfiles still in use
--->  Searching for unused distfiles
No unused files found.
--->  Build location: /opt/local/var/macports/build
--->  Scanning binaries for linking errors
--->  No broken files found.
--->  No broken ports found.

Two questions:

How do I select python-313 to python and python3? Something like

sudo port select --set python py313-python

doesn't seem to work.

ipython (which I already had set with the command below is at 3.13.2).

You may need to reinstall some non-python dependents with an explicit python version variant. It is likely that you can get everything consolidated under one version (or maybe 2, if you really do need the 2.7 stuff.) 'port rdepedents' is useful for finding the ports to target.
