A: Sandbox for Proposed Challenges

String Comparison code-golf You are given two strings \$a\$ and \$b\$ consisting of characters from a to z in lowercase. Let \$n\$ be the length of \$a\$. Let \$m\$ be the length of \$b\$. Let \$a'\$ be the string \$a\$ repeated \$m\$ times. Let \$b'\$ be the string \$b\$ repeated \$n\$ times. Ch...

Q: How Super is this Prime?

How super is this prime? A super prime is a prime whose index in the list of primes is also a prime: 3, 5, 11, 17, 31, 41, 59, 67, 83, 109, 127, 157, 179, 191, 211, 241, 277, 283, 331, 353, 367, 401, 431, 461, 509, 547, 563, 587, 599, 617, 709, 739, 773, 797, 859, 877, 919, 967, 991, ... For thi...

The copy.sh brainfuck interpreter is approximately 3 times slower than a plain compiler without any optimizations, and ??? times slower than a plain compiler with -O3.

I don't know how fast is the TIO compiler, but when I run C++ code with TIO the time used doesn't seem to be very stable.

TwilightSparkle

Wait, the TIO interpreter seems to work differently.

It only outputs two characters for the program I'm testing. I speculate that's because its array size is too small.

Q: The Jaccard Index

The Jaccard index / similarity coefficient, also known as the Tanimoto index / coefficient, is a statistic used for gauging the similarity and diversity of finite sample sets. It was developed by Grove Karl Gilbert in 1884 for the field of weather forecasting [1] and later independently developed...

New in python 3.12:

Variables used in the target part of comprehensions that are not stored to can now be used in assignment expressions (:=). For example, in [(b := 1) for a, b.prop in some_iter], the assignment to b is now allowed. Note that assigning to variables stored to in the target part of comprehensions (like a) is still disallowed, as per PEP 572. (Contributed by Nikita Sobolev in gh-100581.)

This seems useful for golfing, unfortunatly nobody would golf past 3.10 because of the spacing issues

pxeger

How often have you seen the target part of a for loop store to anything other than a local variable? I don't think that will almost ever be used

Q: Zahlen auf Deutsch! (Numbers in German)

Your task is to write a program that recieves a base 10 number from 0 to 99 and outputs the German name of that number with non-ASCII characters replaced with ASCII equivelants. German number names 0 -> null 1 -> eins 2 -> zwei 3 -> drei 4 -> vier 5 -> fuenf 6 -> sechs 7 -> sieben 8 -> acht 9 -> ...

can a submission take input using a data type that is added by a library?

i know the submission would be listed as language + lib

mousetail

IMHO yes but not sure if there is a official rule. As long as the data structure is a reasonable interpretation of what is required in the challenge. Something like a numpy array for a list would be OK

Jacob

ok cool

solid.py

@mousetail What are these spacing issues past 3.10?

mousetail

@solid.py You can no longer do [1for i in range()], you need to put a space between numbers and keywords

solid.py

18:50

@mousetail Oh that's bad... thanks for letting me know.

mousetail

Yea it basically means 3.10 onward is not really viable for golfing, since language versions still compete against eachtother. Except in very special situations.

What useful stuff was actually in 3.10?

There was match case but that's easily replaced with if elif

Q: pairwise traversal of a list or tuple

a = [5, 66, 7, 8, 9, ...] Is it possible to make an iteration instead of writing like this? a[1] - a[0] a[2] - a[1] a[3] - a[2] a[4] - a[3] ... Thank you!

python iteration

@TheThonnu This one I think is useful.

@mousetail that's still only a SyntaxWarning in Python 3.11 and 3.12 (3.12.0 alpha 7, at least)
