So please dear authors when I click on your articles I'd like to have a single sentence somewhere on the landing zone where I can easily figure what we're talking about and not having to read entire paragraphs
Thanks,
Now, readers of HN might not know, and HN's decision (which is, on balance, I think beneficial) to not allow additional supporting commentary besides the title on posts with links to outside articles prevents contextualizing this well for HN readers. (Perhaps allowing one or a small number of supporting links with very brief annotations might be an improvement, but we really do want to avoid Slashdot-style editorializing of submissions, which the current setup does quite efficiently.)

On the other hand, if you use Python, you should definitely check out Jupyter notebooks (formerly IPython notebooks, and now JupyterLab, I guess). They're useful when prototyping data pipelines, since the state of the interpreter is saved, letting you iterate on ideas and see the outputs quickly.
