The silver bullet is Docker. It's not the best solution in every situation, but at least it'll work. For your own projects built from scratch (rather than big multi-dep projects off GitHub), there's a smaller learning curve if you go to the vanilla https://www.python.org/downloads/ https://www.python.org/downloads/ , install the latest, and use the included pip to install packages. That'll probably get you very far. It's not like the older days when you needed both Py3 and Py2. For experts working frequently in Python, tools like Pyenv can make more sense.
