So, I have a python script I'd like to run from time to time from the CLI (on Linux) that resides inside a venv. What's the recommended/intended way to do this?
Write a wrapper shell script and put it inside a $PATH-accessible directory that activates the virtual environment, runs the python script and deactivates the venv again? This seems a bit convoluted, but I can't think of a better way.

The convention

That's one convention. I don't like it, I prefer to keep my venvs elsewhere. One reason is that it makes it simpler to maintain multiple venvs for a single project, using a different Python version for each, if I ever want to. It shouldn't matter to anyone else, as it's my environment, not some aspect of the shared repo. If I ever needed it there for some reason, I could always ln -s $VIRTUAL_ENV .venv.

Learn pyenv

I have used pyenv. It's fine. These days I use mise instead, which I prefer. But neither of them dictate how I create and store venvs.

Shell scripts within Python packages is depreciated

I don't understand if what you're referencing relates to my comment.

The multiple venv for different Python versions sounds exactly like what tox does

Then setup a github action that does nightly builds. Which will catch issues caused by changes that only tested against one python version or on one platform

py313 is a good version to test against cuz there were many modules removed or depreciated or APIs changed

good luck. Hope some of my advice is helpful

Thanks, yes, I use nox and github actions for automated environments and testing in my own projects, and tox instead of nox when it's someone else's project. But for ad hoc, local and interactive multiple environments, I don't.

thanks for the head up on nox. Syntax seems like a tox meets pytest.

Are you using github actions locally? Feel silly making gh actions and workflows and only github runs them

[–] Andy 1 points 18 hours ago

No, I don't use GHA locally, but the actions are defined to run the same things that I do run locally (e.g. invoke nox). I try to keep the GHA-exclusive boilerplate to a minimum. Steps can be like:

- name: fetch code
  uses: actions/checkout@v4

- uses: actions/setup-python@v5
  with:
    allow-prereleases: true
    python-version: |
      3.13
      3.12
      3.11
      3.10
      3.9
      3.8
      3.7

- run: pipx install nox

- name: run ward tests in nox environment
  run: nox -s test test_without_toml combine_coverage --force-color
  env:
    PYTHONIOENCODING: utf-8

- name: upload coverage data
  uses: codecov/codecov-action@v4
  with:
    files: ./coverage.json
    token: ${{ secrets.CODECOV_TOKEN }}

Sometimes if I want a higher level interface to tasks that run nox or other things locally, I use taskipy to define them in my pyproject.toml, like:

[tool.taskipy.tasks]
fmt = "nox -s fmt"
lock = "nox -s lock"
test = "nox -s test test_without_toml typecheck -p 3.12"
docs = "nox -s render_readme render_api_docs"
