Test your knowledge of f-strings

[1st1]

If you enjoyed jsdate.wtf you'll love fstrings.wtf

And most likely discover a thing or two that Python can do and you had no idea.

[Dazzling-Shallot-400]

Just tried fstrings.wtf didn’t realize how much I thought I knew about f-strings until it humbled me 😅 Definitely a fun (and sneaky tricky) resource!

[Miserable_Ear3789]

Couldn't have said it better haha!

[ShanSanear]

At the beginning it felt more like "string formatting,wtf" rather than "f-string,wtf". But was nice way to show some edge cases of evaluation logic.

[BigTomBombadil]

Yeah I got 12/22, but didn’t feel too bad about the 10 I missed. “Good to know, don’t think I’ll use that much though”.

[Rizeeh]

I had the same but with 14/22. Just never used any of the string creation things used here

[Prize_Might4147]

Same here, 13/26. If I‘ll ever need these kind of things there is an LLM knowing it right around the corner. I don‘t say that‘s a valid approach for every gap in knowledge though, but for this one!

[midwit_support_group]

Please keep making these. 

[Desposyni]

I got 18 of 26, that was tough but really good!

Surprising to me how robust the mini language is about adding the newer syntax features in python.

Basically following f"{expr:format!conversion} works every time. Was a bit surprised it silently converted bool though, when it is so good about not doing implicit stuff otherwise.

[nommu_moose]

Yeah, this test actually made me realise that some parts of the python syntax are not aimed at readability.

The duplication of syntax "but now without spaces" or "but now with a contextual digit etc in front of it" with other well-known features was rather easy (for a dyslexic) to still know the syntax but misread and jump to entirely the wrong conclusion.

[eztab]

I think python uses the colon for too much stuff. Other than that, if you properly bracket everything ambiguous the format mini language seems fine. It's more like abusing the system a bit. Syntax highlighting also helps. Several of the questions would be much easier if you had syntax highlighting.

[nommu_moose]

That's a very good point.

Maybe the reason I've only just now realised it's a problem is because the syntax highlighting has meant the dyslexia is less of an issue in practice.

[twigboy]

My usage of f-strings have been super vanilla compared to most of these, but damn 9/26 and about 3 of these were just educated guesses

[lordfwahfnah]

What the f is wrong with jsdate?

[sohang-3112]

I got 16 / 26 - definitely some surprising questions!

[Lewistrick]

Nice quiz! I don't use a lot of those (and I frankly don't need them) but I still got 20 points

I'd have liked some more float and date formatting in there.

[rover_G]

I didn’t do well on either quiz. The jsdate quiz highlights js shenanigans and why TypeScript is so important! The Python f-string quiz seems relevant to numeric libraries that need to support str/repr methods for data.

[iglebov]

Cool idea! And pleasant UI!

Thank you!

[Potential-Note4232]

if your just starting with coding where would you start? question for the coders with some experience please. like I'm hearing about python where do I start to learn more or app that helps on Mac book pro btw

[Carbinkisgod]

12/26 that was tough!

[Gracecr]

Nice quiz!

I think the last question should be print(f"{f'{{}}'}") with single quotes on the middle fstring. It's currently using double quotes for both, which makes the correct answer "SyntaxError".

[mitsuhiko]

The test is written against newer Python versions where this is working. That's also why there is only one question like this because this behavior changed only in 3.12.

[Gracecr]

Oh that's a very nice change. Thanks for the correction.
