Nothing to do with DevOps, more to do with keeping your different projects separate with their own dependencies. That way, if you need to move the package to another machine, you can just do a `pip freeze` to document which packages you need, then `pip install` them on the new machine. If you just want a sandbox area where you'll be developing lots of little scripts and bits and pieces, there's nothing stopping you from having a single environment that you keep adding to as you go. You just miss out on the portability aspects mentioned above and potentially risk getting conflicts over time as the number of packages you install grows and grows.
