Took me forever to find those index expressions. My progression was: <pre class='brush: python'>checkio=lambda n:'Fizz Buzz'[(n%3>0)*5:4+5*(n%5<1)]or\`n\` checkio=lambda n:'Fizz Buzz'[n%-3&-4:4+5*(n%5<1)]or\`n\` checkio=lambda n:'Fizz Buzz'[n%-3&-4:9-n%5-n*4%5]or\`n\` checkio=lambda n:'Fizz Buzz'[n%-3&-4:12-(n%-5&8)]or\`n\` checkio=lambda n:'Fizz Buzz'[n%-3&-4:n%-5&8^12]or\`n\` </pre>

I didn't think I had the shortest solution anyway, and I'm a bit ashamed that so many people have liked it. I must admit that yours is much more creative. I'm sure Veky will agree... Well done!

Well, at least yours was the shortest I had seen, and it made me try harder after my boring initial solution. I just went through all "creative" solutions now and saw that <a href="http://www.checkio.org/mission/fizz-buzz/publications/isisbinder/python-3/second/">isisbinder</a> already had a similar solution, but he didn't minify it and still used a "strip()" rather than pure slicing. He does have nice expressions, though. While I equalized the non-zero remainders with bit operations, he used that n**(p-1)%p==1 for prime p.

Btw, there's a bonus feature: Just remove the space and it does the spaceless "FizzBuzz" version. Negative index ftw.

Wow, maintainable. Now tell it to @cjkjvfnby. :-D

Sorry. It was probably some silly meme. Something like <a href="https://getyarn.io/yarn-clip/1b1f139d-04ca-4413-b89c-9f16bdcf604a,">https://getyarn.io/yarn-clip/1b1f139d-04ca-4413-b89c-9f16bdcf604a,</a> only a bit more polite. :-)

Thanks for that. Learned a lot from your solution.

That's pretty cleaver. Nice.

Have no idea what that code means :-D

Please explain how this works as written? This gives a syntax error when I try to run it. However, changing "orrepr" to "or repr" works.

Hi Thanks for mentioning this. Looks like this solution here is by mistake (when we migrate all the solutions from Py2.7 to Py 3), we are figuring out how did that happen.

StefanPochmann on Aug. 13, 2017, 9:02 p.m.
You can see my original code in my first comment under the solution. It's the last line there. CheckiO changed my `` `n` `` to `repr(n)` without adding the necessary space. Btw, I think it would be better if the comment said something like "Automatically migrated by CheckiO from python 2.7" or "Automatically migrated by CheckiO to Python 3". If people don't already know that CheckiO did that, they might think I did that (and wonder how I did it and why I mention it and where the original is).

oduvan on Aug. 14, 2017, 8:35 a.m.
ok.

It works! Magic? No, Python :)
