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

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.

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

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!
