I'm typically a developer on Windows, and I've done a decent amount of Python on Windows.<p>My workflow is I install the version of Python needed, we're on 3.5/3.6 so we stay pretty current, then use venv and install all my dependencies.<p>When using Linux I've read I really don't want to use my system Python, even if it happens to be the correct version.<p>With Ubuntu specifically, and its package manager, how do I install a different version of Python or how do I de-couple Python from the OS?<p>It would be simple to create some sort of virtual environment and install the requirements inside it but I want to make sure I'm doing the right thing from the start.
