As Nikos mentioned in another reply, you should pay attention to the |
11 |
eselect news items as python upgrades are usually announced weeks in |
12 |
advance. |

I don't see any deprecation notice on |
24 |
https://packages.gentoo.org/packages/app-eselect/eselect-python, but |
25 |
someone could correct me. |

The python package supports installing multiple versions to different |
33 |
slots. The easiest way I've found to run python software that depends |
34 |
on a specific version, without mucking around with global python |
35 |
settings, is to install the relevant version (e.g. emerge python:3.8) |
36 |
and then use venv to run that software in a virtual environment |
37 |
(python3.8 -m venv .env; .env/bin/python something.py). |
