Command pdm py path printing the path towards a Python

[paugier]

Feature Description

Some tools can accept as argument the path towards a Python interpreter. For example with Nox, one can write:

pdm py install 3.12
pdm py list
nox -s build -P ~/.local/share/pdm/python/[email protected]/bin/python

Problem and Solution

It seems to me it would be useful (and very simple) to be able to print the path towards a Python executable with pdm py path 3.12, so that I could write:

nox -s build -P $(pdm py path 3.12)

Since both nox and tox have the capability to create venv's to enable testing against multiple versions of Python, wouldn't it be better to use plugins like tox-pdm and nox-pdm instead ?

In addition to those, there is a GitHub Action available pdm-project/setup-pdm@v4.

Although I do like the idea of getting more info about installed version(s) from pdm py list, is that what you really need?

The problem is pdm py path 3.12 is ambiguous on what python it refers to. There may be more than one python version that matches "3.12"

[klmcwhirter]

The command line might need to be pdm py path [email protected] for example to make it match the output of pdm py list. The idea is still good.

I get frustrated having to hard code paths like that myself. For example, on my host the path is like /var/home/klmcw/.local/share/pdm/... but in a distrobox it is /home/klmcw/.local/share/pdm. I would rather not have to write the script that would use it twice. Or have to manage two env vars.

But as I mentioned some of the existing packages might serve his purposes better.

Let's see where @paugier lands.

Personally, I would use it also for other things than Nox and Tox, for example, simple benchmarks and Mercurial testing, so for me pdm py path [email protected] would be useful.

Also, for me, the nicest behavior for pdm py path 3.12 would be to choose a reasonable interpreter from the data "3.12" (something like the latest CPython I guess), but it's a detail.
