I agree with using Jupyter to get a good grasp of everything that’s going on and experimenting. However, while doing so, I think it’s good to keep in mind building something that’s not in a notebook format as I think notebooks tend to foster bad coding practices.

This is from my experience as someone straddling both academia and a data science position in a startup where I have seen it rampant on both ends (slightly more understandable in academia but terrible for anything that actually goes into production).
