fetch() would need to pull and parse (and cache!) the puzzle page, and lazy_submit() would need to ignore the solution cache and web API to compare with the sample

#

Like I say, the architecture just isn't designed for that

sharp panther
#

What if you copied and modified the functions and put it into a different command-thingy? Maybe that's redundant, and I personally haven't seen the codebase, so I have no idea, but that's just a possible(?) thing.

#

I imagine you could probably get it to work by reading sys.argv for a --test or something but honestly I don't feel like sinking a lot of development time into a feature I'd never use

#

I'll happily merge a PR if you want to do it though

woven sable
#

Maybe add it as a feature in the off-season if you wanted to

When you decide to use it do py -m aoc_helper template <day>

woven sable
#

gotcha, does that jut set up a template for a file?

earnest forge
#

It'll put in all the boilerplate for you

#

Yeah

#

It sets up the imports, the fetch, the functions, and the submit

There's something so satisfying about this tbh

The last weekend is typically harder. The other weekends are more on par, if they're harder it comes down to googling and problem solving.

woven sable
#

ah

#

From Eric Wastl's Leetspeak 2019 talk, he talks about what goes into making each puzzle and how he tries to get the difficulty right, both for each individual puzzle and considering the progression overall

#

iirc I got mentioned in that talk (nope never mind it was the other one)

#

"Weekdays vs weekends" 👀

how hard can it be /s

woven sable
#

earnest forge

🙃

minor cave
#

During the talk he even mentions that for some of the part 1 vs part 2, his part 2 will purposely have a similar concept but then have a totally different set of requirements. To partially simulate the real world of a customer totally changing up requirements on you

woven sable
#

that sounds kind of like day 3

minor cave
#

He talks that some people can predict it (i.e. they can kind of see where it's going and build in flexibility to their part 1 solution, sometimes that means their part 2 takes literally less than 30 seconds) and others don't, so it takes longer for them to change their implementation

signal grotto
#

yeah I'm the second

#

i'm both

#

i'll either make something really flexible, or the most brittle solution ever to exist on my hard drive

ooh yes a little of that too

#

I usually can't break down backtracking problems easily and takes a lot of time for me. I wish there were some tutorials online that were interactive, because I have tried to watch some tutorials then immediately had some question but had no answer

minor cave
#

If you want to kill some time, I do recommend watching the first 8 minutes of that talk

It's very amusing listening to him recount the launch of Advent of Code back in 2015

str.strip 

str.strip([chars])```
Return a copy of the string with the leading and trailing characters removed. The *chars* argument is a string specifying the set of characters to be removed. If omitted or `None`, the *chars* argument defaults to removing whitespace. The *chars* argument is not a prefix or suffix; rather, all combinations of its values are stripped:

```py
>>> '   spacious   '.strip()
'spacious'
>>> 'www.example.com'.strip('cmowz.')
'example'
```  The outermost leading and trailing *chars* argument values are stripped from the string. Characters are removed from the leading end until reaching a string character that is not contained in the set of characters in *chars*. A similar action takes place on the trailing end. For example:

try doing some debugging, even if that means just throwing in random print statements, usually gets things flowing again

also i have a question:
let's say i have a variable x and a variable y where both are lists equal to each other through

x = y

If i run the below code, does it also get rid of the same index on x?

y.pop(some index)
#

because for some reason i was having one variable that was never even touched being changed

woven oriole
#

lists are mutable

frank maple

in 2019 some of my programs were running for like 8 min because they were so inefficient

so yes it will get popped from both

my name is not even in the leaderboard for some reason

hi

my part 2 is successful with the test data but fails with the real data

there is a join command there

#

oh yeah I see

hollow wharf
#

wow doing today's was brutal for me

#

funnily enough, I thought that checking if a board had won would be hard

#

that was a piece of cake

#

but actually running the games was death

sonic silo
#

checking if a board had won is a oneliner

hollow wharf
#

well mine is 3 lines but it's just like that for semantic clarity

i saw day4 using bingo

well yeah

hollow wharf

#

or not

#

maybe this is indeed the big first wall in this year

#

last year it dropped heavily on day 7 and 4 at first

#

iirc

woven oriole
#

👀

hollow wharf
#

I mean

#

this is not a hard problem

#

it's an annoying problem

#

but it's not technically hard

atomic frost
#

yeah they are all do what i say problems so far

sonic silo
#

thats what these problems are

hazy pendant
#

i finished only the parsing part and it took 288 bytes for main.py

hollow wharf
#

noooooooo later problems often require cleverness

atomic frost
#

no but like for example day 10 last year you would have to optimise or it would take forever

sonic silo
#

hmm

hazy pendant
#

to emulate

#

recursiom

hollow wharf
#

yeah. here if you just read the instructions and implement the naïve solution, it works

sonic silo
#

in y2020 d23 p2 (iirc) you had to get a bit clever to reduce time complexity a lot

atomic frost
#

yeah you just have to translate between english and code

hollow wharf
sonic silo
#

or not if you used arrays from the get go

atomic frost
#

but later you have to be clever

hazy pendant
#

right

#

lmao

hollow wharf
#

hashmaps go brrrrrrr

hazy pendant
#

brrrrrrrrrrrrrrrrrrrrrrrrrr

ivory venture
hollow wharf
#

idk how hashing actually works in the language that I'm doing AoC in

hazy pendant
#

use google

hollow wharf
atomic frost
#

yeah there are lots of nicer solutions etc but a working one for these will just be the naive solution

hollow wharf
ivory venture
hazy pendant
#

oh cmon boards is a 3D

ivory venture
#

It doesn't have to be super smart though yeah

hollow wharf
atomic frost
#

but mostly if you are the right time complexity it should work

hollow wharf
#

well anyway done solving today's problem time to go do drugs yeet

ivory venture
#

Don't listen to him kids

hollow wharf
#

uh yeah

#

don't do drugs

#

bad

hazy pendant
#

last year was kind of a moderate challenge
but now even day4 is competence simulator

hollow wharf
#

last year's day 4 was just parsing hell lol

ivory venture
#

Yeah the difficulty rose more sharply this year I think

hollow wharf
#

iirc it wasn't really even a hard problem, just the parsing was a nightmare

ivory venture
#

But we'll see

hazy pendant
#

either the creator got smart or the quarantine changed everyone

hollow wharf
#

ahahaha

#

as someone who does a fair share of teaching, it can be very difficult for someone with a lot of experience to gauge how hard a problem is

hazy pendant
#

bingo? more like bingo for your brain

atomic frost
hollow wharf
#

urgh my code for today is like 100 lines

#

actually it's only 51LOC

#

the rest is comments and whitespace

#

so that's not too bad

#

actually that's similar to my solution for yesterday's

#

this time with a timer so i can take a 5min break every 30min and stretch thisbody

winged trellis
#

was also stuck on part two, i had an off by one error, thought i removed the winning board, but removed the winning board +1 isntead

junior hinge
#

could i ask a question about part 2 here? just the logic. i dont wanna open the spoilers channel before im done

winged trellis
#

so instead of ||removing the board|| i just set it to ||None'|| and it worked out well

junior hinge
winged trellis
#

ask and include spoilers for anything that is spoilery

tidal beacon
#

Honestly today part 2 was just a little modification for me

#

I thought its gonna be a project after part 1, but it was alright

#

@winged trellis could I ask to see your code 😄

tidal beacon

nope, its in my advent of code repo

#

rancid creek
#

tidal beacon
winged trellis
#

the list version is my rewrite

tidal beacon
#

day4.py is like reading a different language to me lol

winged trellis
#

the use of ||dataclasses|| was never really needed

#

but i imagined a harder part2 and felt having the details || in a class|| would help me out

rancid creek
#

202!

tidal beacon
# 
numbers: ClassVar[list] = []
board: list[list[Number]] = field(default_factory=list)

no clue what is going on here haha

#

yea ill check out your rewrite

winged trellis
#

weekend puzzles are more challenging then weekdays, so i expected it to be much harder

tidal beacon
#

what is the first line tho

#

actually 2nd line too

#

the name and :

winged trellis
#

its the syntax you use when you make a || class attribute using dataclassess||

tidal beacon
#

okay so look into dataclasses, got it

#

just cuz im curious

winged trellis
#

start by going to the python docs about the topic

#

its a rather new feature of python, only been around a few years

tidal beacon
#

start = perf_counter() is this to test run time?

winged trellis
#

end - start gives you the correct time

tidal beacon
winged trellis
#

first version 0.13, list version 0.02

tidal beacon
#

.02

#

thats a Pog

#

mine is .13 too but I wouldnt know how improve it too much by myself

#

thats a neat code

winged trellis
#

no real need to optimize something that takes a fraction of a second to run 😄

#

we are really just running it once to get the answer

tidal beacon
#

numbers, *boards = f.read().split('\n\n') what happens here?

#

how come you have 2 variables on the left? not sure if calling it a tuple in this context is right

winged trellis
#

its unpacking

#

the right hand side is a list

loud yew
winged trellis
# 
a, b, c = [1, 2, 3]
tidal beacon
winged trellis
#

this will unpack the three values on the right into the three names on the left

#

but if you dont know how many values you have on the right, you can pack the rest into a name by adding a star

# 
first, *the_rest = [1, 2, 3, 4, 5, 6]
tidal beacon
#

ah

winged trellis
#

first will have the value 1 and the_rest will be the list [2, 3, 4, 5, 6]

tidal beacon
#

I did not know the unpacking thing here

winged trellis
#

so what im doing is getting the first line of the file and the rest

tidal beacon
#

this is some big brain splitting

#

Every time I think im decent, u guys pull tricks out of your ass that I never saw before. Its great

winged trellis
#

python has a lot of tricks, its wise to pay attention during AoC to grab a few tricks 😄

tidal beacon
#

gonna take a lot at dataclasses and itertools chain now I guess

Hello, I wanted to know if one can resubmit the code if it goes wrong.

#

Can we?

restive imp
#

you don't submit the code, only the result. But yes, you can re-submit

hollow wharf
#

There's a submit button near the empty space. That's why I asked, but thanks!

restive imp
#

yes, after you hit that it will tell you if you were right or wrong, but you can try again

hollow wharf
#

I see. Why is it so small, anyway? All code goes in one line and looks uncomfortable

restive imp
#

not code, only the result
Most of the time you will be asked to find/calculate a number.
That number goes into the submit form

hollow wharf
#

Oh, thanks for the clarification. I had believed that we need to enter the code, but that's fine.

#

I FINISHED PART2 DAY4 2021

part1 was kind of easy but part2 made me think of my life decisions regarding ||returning a int instead of a list||

In day 4 (part 1) if I had drawn 6 numbers and there is no winner, then I draw 7 numbers and so on or it needs to end at 6?

basically, for every number u draw, u check if a winner exist at that number

In the 2nd part of Day 4.
||It is written that the 2nd board will win at last, and the total of unmarked numbers is 148.

as it wins when 13 number called.
So, numbers which are unmarked are:

yeah, thats been what ive been tryng to do

mind you that an answer to this day is perfectly legible with 30 lines, and 100 lines is ridiculous for one single part lol

Whew....just finished day 3 part 2 lol. I think I'm already lagging behind

for day 4 part 1 are we meant to assume that numbers are being drawn 5 at a time?

or one at a time

ivory venture
humble copper
#

ok thanks

ivory venture
#

Just to clarify, you draw numbers from the first line in the input. The rows of 5 are your boards

woven sable
humble copper
#

ok

woven sable
#

i'lll probably learn it after AoC is over

ivory venture
#

numpy is magic

humble copper

bc the problem description does them 5 at a time so i thought we had to do the same

woven sable

I saw people complete it in so little lines

humble copper

#

Ah no, they're just fast forwarding to this position

humble copper
#

ok that makes sense

ivory venture
# ivory venture numpy is magic

numpy's slicing is one of the best things introduced to Python by a third party library, although I understand that it might not fit in the general case, as numpy arrays have specific shapes

junior hinge
#

maybe we could have some live workshop with numpy on this discord after AoC ? :))))

ivory venture
#

I'm considering it honestly, I doubt I'll have the time though 😅

junior hinge
#

sometimes the thought is all that matters

unique remnant
#

and seeing other people's solutions helps you get to know about new functions you can use

sonic silo
#

documentation moment

timid kraken
#

So for the inputs of aoc puzzles, how do i store hundreds of them in a list?

unique remnant
#

docs are a bit hard 😭 but yeah it always helps trying to read them

sonic silo
#

devdocs has numpy :o

junior hinge
sonic silo
unique remnant
#

:o I didn't see those. I just jumped straight to [function I needed] doc page

sonic silo
#

documentation isnt just documentation of the code

#

good documentation will generally have a nice quickstart through which you can get the feel of the library, and from there you can branch out

i wish the idea of hoogle was more extended (function lookup based on function signature)

wonder if it's server side or client side

they have randomized input + decides the output using their predefined code , i sus

there's a set number of unique inputs --- say, 100 and you'll get one of those
