Didn’t think I’d learn anything new in this article, but I never knew about f-string’s self-documenting expression syntax. I’ve been doing it myself like a chump!
Most importantly you can't use them with translated strings, so it's not usable for user facing strings unless you don't care. This limits fstring usefulness a lot in the projects I work on.
Go mainly. fmt has some functions to do the same sort of formatting but I loved the minimal syntax in Python. JavaScript has a really nice syntax for it as well actually

I’m not! I’m excited to forget this exists the next time it would be convenient for me to remember it 😋

I worked in python when f-strings were pretty new. Didn't realise why you would use anything else. It just reads better.

Luckily, there's now t-strings (e.g.
t"{buh}") for that use case (among many others). Here's the PEP: https://peps.python.org/pep-0750/NotSteve_@lemmy.ca · 3 pts · 104d
F-strings and .format() are two features I miss from Python whenever I'm writing stuff in another language. The syntax is just so minimal yet powerful

in what language?

reasonable answer

What annoyed me moving from % to format was the loss of “formatting” floats to integers with “{:d}”, now you get a ValueError

Ah nice one

And here I thought f-strings were something that happen when others are forced to read my code.

Formatting strings, the running gag of the Python community.
