You might look at uv, which makes the managing of a virtualenv for your 
program pretty transparent. You declare your dependencies, and then just:

uv run myscript.py

And of course if you don't want to type three words to launch, you can 
put those in an executable shell script in your path, and invoke it with 
a single command.

There was a nice article on this somewhere which I now can't find, but 
the project docs cover the topics pretty well:
