just posted a sandbox post re: exploding dice, I couldn't find a challenge on it

but I could've sworn we had one, anybody remember/know where that one went?

Simulate Exploding Dice Your task is to make a program that takes in an integer n, and outputs the roll of a single n-sided die. However, this dice follows the rules for exploding dice. When you roll the die, check what value you rolled. If you got the maximum for that kind of die (on a standar...

lol that's cool

Conor O'Brien

right?

Maltysen

didn't think that using attributes as a loop var would work

AdmBorkBork

Good grief. Do that in production code somewhere, people will love it.

Conor O'Brien

inspired by this SO question

@AdmBorkBork I just might... maybe I should take this abuse to the logical extreme

I don't know why you would ever want to do this, but now I know you can — Nathan 10 hours ago

Same.

Maltysen

@ConorO'Brien hmmm so it kinda looks like u can loop over any lhs

Conor O'Brien

yeah... I think I can replace at least maps with this mechanic, not sure if reduce/folding is possible elegantly

Maltysen

oh so that's why u can

for a, b in ...

its not symbolic, its actually just using the lhs

u can even do for a, *b and things like that

cool

That's now gotten complicated enough that I, and my limited Python knowledge, can't follow along, but I'm sure it's cool.

Q: Make it rain characters

Inspired by this chat mini-challenge. Given a string as input (ASCII printable characters only), output the string with the letters "raining" down. Each letter must be a random number of lines downward (random between 0 and the length of the string, each having non-zero probability), and only on...

Q: Are non-uniform random distributions allowed?

I posted a challenge that requires programs to generate a random number in a range, and one answer used the rgeom function from R. This function uses a geometric random distribution. Is this allowed by default for challenges requiring random values? I'm inclined to think not, since the dictionar...
