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

      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.

        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/

    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!

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

    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

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

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

      {:.0f} always works though for floats or ints

    Formatting strings, the running gag of the Python community.
