Python: show full interpreter path in UI

[isabelizimm]

The way Python interpreter paths are created/managed, often times the useful part of the path (eg, the directory where a venv lives), is truncated from the current drop-down. It makes it frustrating to navigate through numerous virtual environments that might be nested in a directory, since the only way to view the path is to hover over each one.

It would be ideal to have the full Python interpreter path displayed in one or more locations:

• where the selection of interpreters happen, in order to select the right one
• viewable on selection, to quickly confirm the correct one was selected

Some ideas for where the path could live:

+1. Adding another visual to show how difficult it can be to know what venv you're using or selecting.

In addition, maybe if the venv is named .venv we can show its parent directory in the name instead of .venv? So if you have it at ~/projects/positron-ipykernel/.venv the name would become: Python 3.12.3 (Venv: positron-ipykernel)
