I had a whole rant queued up on "Pandas and its consequences have been a disaster for the human race" (well, at least for newbie programmers), but I think instead I want to focus on the damn dictionary splats. I just don't get it - it's pure "clever" code in the pejorative Dijkstra sense. It's hard to edit, it's hard to typecheck. Why not pay the very low whitespace tax to give each key/value pair its own longhand line:

  .astype({
    'central_air': bool,
    'ms_subclass': 'uint8',
    ...
  })

Now if, say, ms_subclass and overall_qual need different types, that's an easy diff to read. Ah, but I suppose that wouldn't be as Twitter-friendly.

I’m on the same page with formatting, it’s not a pandas thing. (Doesn’t actually look like you’re saying it’s only a pandas thing) The same formatting patterns happen in all languages I’ve seen, sql quite often.

It’s just a bad programming habit thing.
