Hm, a venv with interpreter is good enough and setup from nothing within 30 minutes still.. then if you have the right libs you are ready to go. Still doing that. Most of my (admitted, simpler) scripts from 10 years ago usually run fine without any fuzz or even with later libs - good if one embraced py3 early and isn't stuck with py2 still after EOL ;) This sure depends on libs chosen and also implementor ( yeah I also know people who claim there code breaks ever few months... I don't know why). I would claim that Fortran's stability only comes from the fact that ecosystem and libs were not really evolving anymore... you have that also in any compiled or also scripted language if you have these conditions or keep the stuff sround? In the end that's why numpy wraps Fortran libs! :D
