Q: Schlafli Convex Regular Polytope Interpreter

Background The Schlafli Symbol is a notation of the form {p,q,r,...} that defines regular polytopes and tessellations. The Schläfli symbol is a recursive description, starting with a p-sided regular polygon as {p}. For example, {3} is an equilateral triangle, {4} is a square and so on. A reg...

In the video it's basically mp3 converted to midi and it sounds like voices but it's played on piano

@ГригорийПерельман It is certainly too hard to HNQ but I think it is a really interesting challenge and I have been trying to think of an algorithm to solve it for while now.

I actually came up with a python quine! I've never been able to write a quine in a language other than vim before, lol

f='f={};print f.format(repr(f))';print f.format(repr(f))

Good job!

@DownChristopher you realize for your multi part challenge, it's definitely a dupe of each individual part?

Down Christopher

@Riker Wait what

How again?

Riker

the scoring doesn't actually take the multiple part-ness

you're basically just saying "whoever is the shortest over all the challenges"

Down Christopher

I have 2 of 3

Riker

yeah

Down Christopher

9:39 PM

the 3rd will tie it together

Q: Should multi-part challenges be allowed?

We occasionally have challenges which consist of multiple separate subchallenges, whose individual scores are simply combined at the end. These are often known as "golf courses". While these are often quite popular they do have some problems. Mainly it's not clear how we should deal with people c...

tl;dr: unless the challenges are directly related in topic or by [restricted-source], you can't really make multipart challenges

It is still in sandbox

It may end up being different challanges idk

@DJMcMayhem This is basically the standard Python quine except you can use % instead of format and %r for repr

Quine writing can be a bit of fun if you go in blind.

it would be so cool if you could use commas in conditionals, when the second one can only be true if the previous one is true

if x, and x[0] == "h": print("hi")

but syntax error ;_;

TacoLemon

Is that Python? That's implicit in Lua.

a and a[1] works like that.

Григорий Перельман

@DestructibleLemon You have invented the logical and, congradulations.

TacoLemon

Some languages will still attempt the second half of the expression, which throws an error.

Helka Homba

@DestructibleLemon In what language? That should work in python

Destructible Lemon

@HelkaHomba nope it error

Without the comma

The comma is not needed

Destructible Lemon

yeah I know

ASCII-only

Languages do it automatially

Destructible Lemon

but it would just be nice if you could use a comma

ASCII-only

For python and does that, for most other languages && does that

Destructible Lemon

because of english grammar

I know

it would just be nice

TacoLemon

11:13 PM

English grammar is silly.

Destructible Lemon

to be able to use a comma like that

@TacoLemon not all of it

Григорий Перельман

@ASCII-only You mean &&

|| is or

@DestructibleLemon well I use the heretic comma

Helka Homba

@DestructibleLemon I mean if x and x[0] == "h": print("hi") works fine without the comma. and short circuits

Destructible Lemon

this isn't about heretics and oxford

TacoLemon

Oxford or bust.

Destructible Lemon

@HelkaHomba I know

it would just read nicer

it wouldn't change the reult

it would just read nicer

Helka Homba

ehh

Destructible Lemon

11:16 PM

@ASCII-only this isn't to do with oxford commas

also heretic comma is evil

enjoy your endless garden path sentences

TacoLemon

I enjoy X, Y and Z looks like you're telling Y and Z that you like X, when this is clear if you say I enjoy X, Y, and Z.

I use whichever comma format makes the sentence easier to read.
