> I don't get the people here saying don't use Jupyter notebooks, or they are bad software engineering. I have a python window open on my desk right now. But the model of programming here contrasts sharply, in my mind, with the one discussed yesterday, from HtDP https://news.ycombinator.com/item?id=17826959 https://news.ycombinator.com/item?id=17826959 . I absolutely use the REPL, for instance to determine where to put what arguments into a library function. But I have also in the past had it happen that I found a routine of mine that missed an edge case and there were a good number of projects that subsequently used that routine, that now could be wrong. Some of those could have led to a publication, so there could in that sense be a permanance to that error. Oops. Those of us who have gotten bit, or who teach and routinely see students develop habits we know will lead to them getting bit, worry about systems that are not developed so much as pasted together.
