The environment variable you're thinking of is `PYTHONUNBUFFERED`, not `UNBUFFERED` [0]. If you want a generic solution to this problem, try the `unbuffer` command [1]. For anyone who's interested, I recommend reading Julia Evan's article [2] about this problem and its solutions.

The Julia article was a good read. Probably something I run into once a year, but glad to have a better understanding of it.

  Julia Evan's article is a great write-up indeed, I'll submit it as a main link. It's "Julia's article", not "The Julia article". Update: it is was on here just a month ago actually: https://news.ycombinator.com/item?id=42275033 https://news.ycombinator.com/item?id=42275033

    It's Julia Evans' article, not Julia Evan's. I don't know if Julia Evan even has an article.

      I was taught that the s is omitted after plural nouns, not after nouns ending in s. Julia Evans's house, but the Evans' house.

        FWIW, I'd accept either one. Some names don't take an extra s by convention, like Jesus, but otherwise it seems in practice that names that feel like plurals don't get it. I'd write "Jess's" but "Jenkins'". (I consider myself a follower of Lynne Truss's, and have deliberately not considered a grammar reference for this answer, as I'm sure this is within the interested reader's ability and shan't spoil these readers' fun.)

Thanks, I forgot about the PYTHON prefix, fixed it. On MacOS, can install via homebrew's `expect`: https://apple.stackexchange.com/a/193152/330523 https://apple.stackexchange.com/a/193152/330523 Apparently I knew about this 2.5 years ago as I commented on the accepted answer back then.
