[iw4p]

All instances of string formatting have been converted to F-strings for increased readability and performance. Before that some of strings use .format and others use f-strings.

If this is just a refactor, why the fix: on the commit message (8c600f7)?

Usually the most prefixes are fix and feat, but sometimes some repos and projects use other keywords like chore, ref, etc.
reference.
By the way I modified the commit message prefix.

You should read our developer notes for an overview of what is relevant to our project. ref doesn't mean anything here. You could probably use refactor:.

Sorry, I'm a newbie. I read this and only saw this tagging for PR title. Now I changed it to refactor.

Concept NACK. Thank you for looking into this, and I support increased f-string usage, but imo this should be done organically whenever these lines are touched for other reasons (or with a scripted-diff across the code base, and enforcing it with linter, should there be support to do that). In its current form, this is not worth the review time imo.

Hi,
Thank you.
I touched this file to optimize it like using built-in python request library instead of curl and decreasing the request numbers, and one more PR. That's why I decided to go for converting strings to f-string.

Thanks for your interest in contributing! CONTRIBUTING.md and developer-notes.md contain good resources for beginners. As we have 300+ pulls open right now, closing this test refactor to focus review attention on the others (see https://github.com/bitcoin/bitcoin/blob/master/CONTRIBUTING.md#refactoring)
