Until now I just deal with that by always explicitly specifying the whole path to the python executable. Granted my needs are very run-of-the-mill, but wouldn't that suffice for many people? I've tried several times over the last few months to get into all this python environment/package stuff, but it all feels like yak shaving... much like the hours and hours I spend customizing vim years ago, which were fun (at that time) but which weren't 'productive' in that they'll never in my lifetime pay themselves off.
I maintain a mix of old and new python projects (sadly, still working on migrating some older 2.7 stuff to 3) and my setup is the same as TheChaplain. I just keep a separate venv for each project and have it setup appropriately in VSCode. With VSCode, I don't even have to think about which venv I am working with outside of when I initially set the interpreter.
