    Just use the python interpreter in the venv in the hashbang line.

    For example, here's the first line of one my scripts:

    #!/usr/local/share/wds/venv/bin/python3

    As you can probably guess, the venv is in /usr/local/share/wds/venv.

    There is no need for wrapper scripts which activate the venv. Python
    does that all by itself.

    I have a small script, install-python[1], to assist with setting the
    hashbang, but if it's just a few scripts you can simply edit it manually.

    OP here. Yes, thank you, I thought that the shebang line would do the
    trick but it's nioce to have it confirmed.
