Python • Re: activate venv from script?

I have a setup with a headless pi and the gravitrax bluetooth bridge.
I'd like to have a script running on boot, this script will wait for a button push.
When I push the button the program needs to connect to the gravitrax bridge, this uses a library I installed in a venv.
So my question is, how to activate the venv ?

1. Code:

   source $HOME/venv/bin/activate && python my-program.py

2. Use a shell swcript:

   Code:

   #!/bin/bashsource $HOME/venv/bin/activatepython my-program.py

3. Use the python interpreter in the venv directly:

   Code:

   $HOME/venv/bin/python my-program.py

Or is it better practise to have the venv active all the time?

is this possible on boot?
