eww

no diploma for you

[vale wasp]

Diplomas are overrated. It's the education that matters.

[tame raptor]

@silver plover i remember 2 yrs ago i hated coding now it makes me happy

[chilly whale]

both are important, tbh

you'll get further with an education and a degree than with only one or the other

[vale wasp]

As a man without a degree, I know.

[pallid garden]

what does the s argument mean

[pallid garden]

oo

[tame raptor]

yooo i just imported my first thing in py 🙌

[grim hatch]

Euler's number

[vale wasp]

Text him... See if he responds.

[grim hatch]

The rate of change in an instant

[pallid garden]

ive been typing in his number for awhile now, how long is this number???

this is going to take forever

[vale wasp]

[runic flower]

Try using binary instead.

[grim hatch]

Text who? Euler? I hardly know her

🥁

I'll take the L on this one ngl

[vale wasp]

If you don't reach out, you never will...

[pallid garden]

this is going to take 10000....?

[grim hatch]

What the hell is that supposed to mean Dan

[vale wasp]

If you don't text someone because you hardly know them you'll never get a chance to get to know them.

[grim hatch]

You know, in the midst of my python projects, I think it'll be healthy to do fun or stupid projects so I dont get bored

[vale wasp]

Well played.

[grim hatch]

OH I thought we were still joking about Euler 😭

[vale wasp]

I was riffing on that but it's real projects.

[grim hatch]

I love math, so this could definitely be interesting

[pallid garden]

are they complex?

no rational person will spend so much time on these, right?

[vale wasp]

They're rational.

[runic flower]

ok, raise your hand if you mispronounced Euler having only read it before finding out how it actually sounds.

[vale wasp]

🖐️

[pallid garden]

i didnt actually, i read about euler in murderous maths, which explained how to pronounce euler

[grim hatch]

i would

(Did you get it)

[runic flower]

Ah, nice!

no thanks, take back this gift cursed creation

another American invention?

[rare gazelle]

[vale wasp]

Do not blame the US from imperial measurements. Blame the pirates for us still using them.

[fiery yarrow]

alexander the ok is british, btw

complaining about units used on british rigs in the north sea

[vale wasp]

I'm kinda surprised nobody asked about the pirates....

[floral terrace]

How are pirates even involved

[vale wasp]

Thank you!

[floral terrace]

just did lol

[raven urchin]

ts gave me such a fucking headache, now I learnt that I have to appreciate regex

for prefix in ["!e ", "!eval "]:
    if reaction.message.content.startswith(prefix):
        code = reaction.message.content[len(prefix):].strip()
        break```

[vale wasp]

Thomas Jefferson, the 3rd president of the US, was a Francophile and ordered a set of standards from France. Pirates raided the ship and stole the standards. And the rest is history.

[raven urchin]

(it breaks)

[vale wasp]

Regex is wonderful!

[rare gazelle]

the only word i understood is pirates

[craggy willow]

verb or noun

[floral terrace]

still, how does that relate to the US bad choice of unit measurement?

[rare gazelle]

😵‍💫

[vale wasp]

Imperial came from the UK. So it was what was used by the colonists before the US existed as a country.

[raven urchin]

Tomorrow ill change that for a pretty regex, along with the rest of my alike-stuff

[vale wasp]

Metric wasn't around until the French revolution.

[vale wasp]

You can have regex or pretty but not both.

[rare gazelle]

A Francophile is someone who has a strong affinity, love, or admiration for France, its people, language, history, and culture

francophile sounds bad though

[vale wasp]

Indeed. And Thomas Jefferson was one.

[raven urchin]

what i'm thinking is pretty simple tbh

[vale wasp]

Very famously.

[vale wasp]

https://pythex.org is your friend.

[floral terrace]

cool, good to know the Brit used to have such a severe feet fetish they made it a unit of measurement

[rare gazelle]

words ending with phile aren't so pleasent usually

[raven urchin]

TYYY

[fiery yarrow]

uh cap

@raven urchin

import math

pizza_area = round(pizza_area, 1)

[vale wasp]

Snopes blocks ad blockers so I can't see that.

[raven urchin]

I made something like that once lol

[fiery yarrow]

hmm glorious lets me see it
anyways, not-really tl;dr:

While it was true that physical items to demonstrate metric standards intended for Jefferson did not make it to him because of piracy, there was no plausible alternative history in which the delivery of such items would have overcome the political stalemate over establishing a standardized measuring system — no matter if it was the decimal-based metric system or something else.

At the time of Dombey's death, Jefferson was already convinced of the virtue of these ideas. Congress was not. As such, we rate the claim that piracy prevented the U.S. adoption of the metric system as "False."

[rare gazelle]

pirates used to steal everything huh

[tame raptor]

Im going to make a price to area ratio now with if statments

[floral terrace]

zoomer-to-english translation: It's wrong

[vale wasp]

There's a lot more than just the pirates but that is an interpretation. Maybe if the standards had arrived Congress would've been convinced. Who knows?

And it's a fun story even if the interpretation is far-fetched. Jefferson could've had another set sent over.

[rare gazelle]

very nice

[pallid garden]

lol yea

[flint cloak]

i thought there was an attempt by the us govt to switch to the metric system during the cold war but the public went bananas

[pallid garden]

that's humans for ya

[vale wasp]

They started teaching it in the 50s IIRC but it has not caught on outside of the scientific community.

[brisk gazelle]

Outside the country, however...

[floral terrace]

how are they cool with using the metric system for measuring bullets tho

[vale wasp]

Leave our freedom units alone.

[vale wasp]

That needs precision.

[floral terrace]

🥀

[floral terrace]

I'm sorry, I can't think of any other thing to say rather than such a generic zoomer emoji

[vale wasp]

You are not getting any arguments.

But the fact is that things that have smaller tolerances use metric.

[grim hatch]

I love how my Linux teacher keeps mentioning Galiger's travels when explaining why some commands do the same thing but at the same time are used differently

[flint cloak]

[flint cloak]

analogies and metaphors have no place in CS

[grim hatch]

Yes. Cause we are killing parents and leaving orphans in CS.

[vale wasp]

That's not true. They can help open the door for a more detailed explanation. But you need to be careful with them.

[raven urchin]

damn...

[grim hatch]

CS is full of metaphors

[vale wasp]

We are aware of LLMs. Yes.

[grim hatch]

...not even that...

When a parent process is killed and leaves a child process running, the child process is now called an orphan process

[flint cloak]

at best, they don't introduce inaccuracies, at worst they make the current dev netscape

[grim hatch]

Think about that next time you kill a process

[vale wasp]

Kill all the processes. Got it.

[raven urchin]

kill the child first

[flint cloak]

processes aren't sentient, so i'm pretty sure you can go Machete on them

[raven urchin]

machete mentioned !!!!!

[vale wasp]

Murder the child and make the parent watch. Got it.

[raven urchin]

😭

Dan

thanks for the regex thingy

[vale wasp]

They aren't sentient, yet.

[raven urchin]

I think my problem is fixed now

[vale wasp]

You're welcome.

[vale wasp]

Now you have another problem 😉

[raven urchin]

probably!

thats the magic of programming HAHA

[vale wasp]

That's the way life works. Fix one problem and stumble on another.

[spice hill]

The 9x19mm Parabellum cartridge, commonly referred to as just "9mm", was developed in Austria, hence the unit.

[vale wasp]

I didn't ask - how were all the tests? You ace all the classes?

[raven urchin]

ofc, most of them are either over or 2 - 1 point away from 90

[vale wasp]

Nice!

[rare gazelle]

very nice

iet could do for a nice dystopian sentence, indict spmepne to become a computer process, get them stuck in a race condition

[fiery yarrow]

their official status page is lying, but others tell the truth: https://downdetector.com/status/discord/

[vale wasp]

Sounds like Tron.

[flint cloak]

lmao, i would watch that Tron

[spice hill]

If you want more useless ammunition facts: in Russian/Soviet tradition, the caliber is measured by the inner diameter of the rifling, but in the rest of the world by the outer. So the 9x19 Parabellum's bullet is 9mm in diameter, but 9x18mm Makarov's bullet is 9.27mm.

It's like kilobytes and kibibytes

[vale wasp]

0.22 caliber is also 5.56mm

[floral terrace]

nah, in this case, I'll take my "blissful ignorance" pill, thank you very much

[rare gazelle]

these guys are trying to disease us

[spice hill]

Who knows what facts you'll need in the apocapylse

[vale wasp]

Having knowledge is never bad.

[rare gazelle]

how do you even know this fix

[spice hill]

I have no idea. I've never shot a live firearm in my life

[vale wasp]

I know it because of my time in the IDF.

[fiery yarrow]

because you killed them all first and shot dead firearms?

[floral terrace]

even occult knowledge which will get you targeted by fanatic cultists?

[vale wasp]

Knowing is half the battle 😉

[flint cloak]

yes

[raven urchin]

what's the IDF?

I think I know but I forgot

[flint cloak]

Internet de France

[brisk gazelle]

Israel's armed forces.

[raven urchin]

wouldnt that be IAF? 😭

[raven urchin]

That makes sense. Do they do python?

[raven urchin]

Nope, but I have funny ideas

[vale wasp]

I imagine. There's Python everywhere.

[rare gazelle]

the probblem with the topics is that they're bad

[raven urchin]

the dominican programming language HAHA

[fiery yarrow]

Suggest more topics here!

[vale wasp]

Programming, no. Tried making a language with friends in school umpteen years ago.

[vale wasp]

So suggest more. There's a link.

[spice hill]

I never knew this google form even existed. No clue how to see the results

[rare gazelle]

i think grey suggested some

[raven urchin]

Wanna hear something funny?

[vale wasp]

Always.

[vale wasp]

I hope someone does. We need new topics.

Hi chat

[zealous lion]

yay or nay?

x = async lambda: None

[vale wasp]

Nyet.

[rare gazelle]

i like it

[raven urchin]

That for loop i replaced with a regex was super annoying, because it worked, but was easy to break. So easy we didn't even notice when testing it.

I used THE EXACT AND ONLY WAY for it to work, and all others just wrote all the ways that didn't work.. So we thought I messed up the permissions or some ownership check of the messages, but it was formatting, it's always formatting 😭

[velvet trout]

a CPython core dev randomly appeared

[deep dome]

I've tried making an esoteric programming language, but lost motivation 😅

[zealous lion]

yes hello

[rare gazelle]

throw a pokeball at him

[vale wasp]

It's always formatting.

[raven urchin]

hi CPython core dev aggresive

[spice hill]

I think the problem is that the topics are personal, rather than discussing something third-party. Very few people posted an actually useful PyPI package for example. And it's going to be those 3 people repeating it.

[raven urchin]

hru tonight?

[rare gazelle]

what you decided from yesterday

[zealous lion]

now why not:

async if x == y:
    ...

if x async in y:
    ...

[velvet trout]

[zealous lion]

still writing it up, probably going to do async yield from

there is no ieq dunder i think

[spice hill]

Maybe.

[fiery yarrow]

are you actually trying to pr this to cpy

[rare gazelle]

no icontain

[zealous lion]

no

[rare gazelle]

a i mean, not i

[zealous lion]

__abool__, __acontains__ or whatever the dunder is

aeq, acontain

there's acontains?

@wise imp what's the difference between event.dict["size"] and screen.get_size()?

[vale wasp]

April Fool's Day.

[rare gazelle]

oh, didn't even think of it lol

[silver plover]

We really should have more April 1sts in a year.

[vale wasp]

The day when we must believe everything on the internet.

[vale wasp]

365.25 aren't enough?

[rare gazelle]

a real april first prank would be on the last day of march

[velvet trout]

[rare gazelle]

got confused for a second

[velvet trout]

[fiery yarrow]

do you mean march or are you proposing we name months after categories of purchasable objects

[rare gazelle]

english is exhausting

[chilly whale]

there's 365.2425 days per year

[fiery yarrow]

There are currently about 365.2421875 solar days in one mean tropical year
sure about that, godly?

[velvet trout]

Nuke English

[velvet trout]

+, -

[velvet trout]

Is all i know in sign language

[wise imp]

there's event.dict? anyway, you can just do event.size probably, but also, probably no difference in the values if you compare them at the same time? one is just an event, that's all

[velvet trout]

[chilly whale]

that's a tropical year, 365.2425 is the number of days in the average Gregorian calendar year

[rare gazelle]

wow, thats insulting

[fiery yarrow]

nice try

[final hollow]

w, h = (dim - 100 for dim in pygame.display.get_desktop_sizes()[0])
screen = pygame.display.set_mode((w, h), pygame.RESIZABLE)
pic = pygame.image.load("assets/temp.jpg")
clock = pygame.time.Clock()
running = True

while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
        elif event.type == pygame.WINDOWRESIZED:
            screen.blit(pygame.transform.scale(pic, event.dict["size"]), (0, 0))
            pygame.display.update()
        elif event.type == pygame.WINDOWEXPOSED:
            screen.fill((0, 0, 0))
            screen.blit(pygame.transform.scale(pic, screen.get_size()), (0, 0))
            pygame.display.update()

I'm just trying to make the screen resizeable and according to some old documentation I needed all this

[fiery yarrow]

hmm, so it seems

[chilly whale]

the Gregorian calendar has a surprisingly complicated leap year rule that results in the .2425

a year is a leap year if it's divisible by 4, unless it's divisible by 100, unless it's divisible by 400

[fiery yarrow]

unfun fact: there's disagreement of whether year 4000 is gonna be a leap year or not

[chilly whale]

it should be - it's divisible by 400

[rare gazelle]

luckily we won't live by then

[wise imp]

to make the window resizable, all you need is the RESIZABLE flag, resizing contents is, of course, a separate thing

[final hollow]

ohhh I see

[rare gazelle]

unless medicine will evolve insanely, and then we won't be so lucky

[fiery yarrow]

unless we add another exception to the rule filled with exceptions to make it slighter more accurate, and then maybe another exception around year 20 thousand

[chilly whale]

sure, but if we change the rules it's no longer clear that we can call it the Gregorian calendar

[rare gazelle]

whats special about 4000 or 20k

[fiery yarrow]

that's basically why we haven't done it yet:

thus reducing the average length of the calendar year from 365.2425 days to 365.24225. Although this is closer to the mean tropical year of 365.24219 days, his proposal has never been adopted because the Gregorian calendar is based on the mean time between vernal equinoxes (currently 365.242374 days)

[raven urchin]

One guy tried to program a Hello World in binary and just quit midway through😭

[fiery yarrow]

a smart fella programs hello world in python, and a text-to-binary converter in python that translates the first one

[ashen cipher]

tbf if we have an exception for 4000 does that not include 8000, 12000, 16000, 20000?

[raven urchin]

🧠

[rare gazelle]

how about no...

[ashen cipher]

i am not a smart fella

[raven urchin]

this is actually something fun, it sounds easy

[fiery yarrow]

the proposed rule would alter years 4k, 8k, 12k, etc to be common years, and then possibly another rule to alter 20k, 40k, 60k, etc to be leap years again

[ashen cipher]

i program hello world in rust 🚀 blazingly fast 🚀 🚀 memory safe 🦀🦀🔥

[fiery yarrow]

tl;dr orbital dynamics sucks

[wise imp]

"programming in binary" meaning writing raw machine code?

[raven urchin]

he was writting 0s and 1s, idk how legit that was

[rare gazelle]

maybe he knows only binary

[raven urchin]

It was a youtube video about "the worst ways to program"
he tried in a minecraft book and quill, and had to farm for them 😭

[rare gazelle]

this server is only english though

[raven urchin]

he also tried nintendo ds pictochat

[rare gazelle]

you can use a binary to english translator though

[raven urchin]

the video was funny af, also he gave Vim an F.

[tame raptor]

holy fuck i just created a masterpiece

its 11 pm rn

[raven urchin]

SHOW SHOW

[rare gazelle]

very nice

[ashen cipher]

basically not at all

[zealous lion]

I guess it would be possible to write machine code in only 0s and 1s but in practice the only 0s and 1s are going to be physically on your CPU

[floral terrace]

me when I bin()

[raven urchin]

oh we share huso horario 🗣️

(timezone)

[tame raptor]

ET

[zealous lion]

you would just need an additional translation layer to convert the bits into actual data

[raven urchin]

he was translating from an ascii table

[zealous lion]

you can't write machine code with an ascii table

[rare gazelle]

._.

[raven urchin]

then thank god my friend quit

imagine spending 3 hours writting meaningless 0s and 1s just to figure out it wouldnt work anyway lmao

let me find the video so yall suffer too

01101000 01101111 01110111 00100000 01100001 01100010 01101111 01110101 01110100 00100000 01101110 01101111

[spice hill]

By then, we should develop technology that would slow down Earth's movement around Sun such that each year is actually 365.25 days. Not 365, because that would break a lot of existing software.

[fiery yarrow]

i'm sure nobody would have a problem with this idea

[raven urchin]

He gave Vim an F tier on his "horrible" list (which means least bad)

that's hilarious, thats like getting Vs code in it for no actual reason 😭

[rare gazelle]

least bad?

the ranking is most bad gets highest rank?

[wise imp]

no, let's slow it down to a round 360, that way we are matching with degrees

[raven urchin]

The tier was "The most horrible"
So uprank means worse.

the highest was his attempt of coding in ascii 😭

[velvet trout]

[raven urchin]

also somehow he liked coding in a minecraft book and quill 🔥

wait, true, going to 360 is not a slow-down, it's a speed-up

[fiery yarrow]

@dusty ember get weary pinged lol

[raven urchin]

yes, i kinda messed up the explanation

[rare gazelle]

except people living in the sun

AAAAAA

[velvet trout]

if my ducks get scared, i am reporting y'all!

[rare gazelle]

imagine you do what fix said, and end up ruining it for other planets, thats kind of funny

[wise imp]

how long would it take to achieve such speeds in a way that we don't feel the effects of the acceleration?

and is such a speed even achievable

without disintegrating earth

[spice hill]

that's a sacrifice I'm willing to make

[fiery yarrow]

probably about a zillion years

[keen fox]

What fix says?

How much is zillion

[rare gazelle]

^

[limpid meadow]

We just have to increase the diameter of earth's orbit, ezpz

[silver plover]

the trick is to do it backwards. No acceleration, just a lot of deceleration.

[dusty ember]

what's good

[velvet trout]

[spice hill]

It's year 3000, we failed to stop producing too much greenhouse gases, so we just moved Earth further from the sun

[fiery yarrow]

but based

[keen fox]

It's just a silly fork of it

With based features

[zealous lion]

what features does it have

[keen fox]

Based ones?

[zealous lion]

such as?

[chilly whale]

it adds some features that pylance has but pyright doesn't, changes some defaults to make type checking more aggressive by default, and adds the ability to set up a project baseline so that basedpyright in CI only complains about new stuff and ignores existing lines

[ashen cipher]

[keen fox]

No microslop

[chilly whale]

I don't think that's true

[zealous lion]

you guys will find any reason to hate on ms

[chilly whale]

I'm pretty sure features added to pyright get ported to basedpyright

[zealous lion]

out of curiosity, which features does pylance have that pyright doesn’t? it’s been a while since I last used pylance, but pyright has been pretty great for day-to-day work

[chilly whale]

the thing where parameter names show up if you hover over function calls is the big one I know of

[ashen cipher]

semantic highlighting, lsp jump, completion, auto-import, a few more things

[spice hill]

There's a list of things here: https://docs.basedpyright.com/latest/benefits-over-pyright/pylance-features/
docstrings for compiled builtin modules, hover and "go to definition" on operators and go to implementations are pretty cool

[ashen cipher]

that's just the ones basedpyright has that pyright doesnt

[chilly whale]

"inlay hints" is the one I was referring to

[spice hill]

Auto-completion, go-to-definition, and import suggestions while typing are already present in pyright

[ashen cipher]

my info seems to be outdated

[spice hill]

those things have always been in pyright

[zealous lion]

oh hot take but I can’t stand that

it gets all messy when I type

the other stuff looks cool though

[ashen cipher]

hm, i just got it from https://github.com/microsoft/pyright/issues/1859 here

[spice hill]

I too hate inlay hints in Python

[velvet trout]

inlay what

[zealous lion]

I haven’t enjoyed them in any language, but I haven’t tried them too much

I bet it’s a rust thing

[spice hill]

yeah, I find them useful in Rust when chaining methods

[tropic temple]

its like really overwhelming in rust

imo

[zealous lion]

called it

[tropic temple]

but i do like enabling implicit drop inlay hints

and its useful in iterators

[velvet trout]

What's inlay hints?

[zealous lion]

i’d be fine with them if the LSP was actually able to keep up with me, but usually they just get out of date or mess with my cursor

[velvet trout]

Inline hints?

[ashen cipher]

i just enabled it, am gonna try using it for a bit

[zealous lion]

it’s like where the editor shows you type hints on things that you didn’t actually add type hints for

[tropic temple]

its insane when you have really deep type generics

like with iced

[velvet trout]

[tropic temple]

they keep just poppin up everywhere and shiftin the cursor around

[zealous lion]

hate that

[chilly whale]

heh. I hate semantic highlighting

I have no idea how everyone else has decided that it's a good thing to have every word on the line colored a different color

[brisk gazelle]

I think it's fabulous. 🏳️‍🌈

[spice hill]

In VSCode and Zed, there's an option to only show inlay hints when you press a button. In VSCode it's "editor.inlayHints.enabled": "offUnlessPressed", and I think the default combo is Ctrl+Alt.

[ashen cipher]

i personally rather like it although my theme is comparatively low contrast

[brisk gazelle]

Like, legitimately. For me, it increases readability.

I wouldn't want it in written English.

[chilly whale]

I find it incredibly distracting.

[pallid garden]

oh ho

i have inlay hints turned on for literally everything

[spice hill]

With that enabled, a lot of inlay hints that would make the code unreadable become extremely useful. It's like showing the type on hover but better.

      "tuple[str, UnionType]" is not assignable to "Tuple[str, type]"
        Tuple entry 2 is incorrect type
          "UnionType" is not assignable to "type"``` but that requires me to exit (n)vim

also i cant extract that into a type alias

[spice hill]

Indeed, type[T] is for classes. a1 | b1 is not a class. If you want to accept arbitrary type hints as arguments, you should see TypeForm (it is stable, but for now only available through typing-extensions)

[ashen cipher]

not my library

:(

[spice hill]

What's the library? And what function are you using?

[ashen cipher]

msgspec.defstruct

[chilly whale]

by binding a key to vim.lsp.inlay_hint.enable(not vim.lsp.inlay_hint.is_enabled())

[ashen cipher]

annoying thing too is that it allows it and it shows it in an example

[spice hill]

Why are you using it instead of the class-based approach?

[wise imp]

I should maybe try harder to use more vim

[ashen cipher]

one of the fields im decoding has a hyphen and python doesnt like that

[wise imp]

btw @chilly whale how do you say get your config across machines? like if you ssh into some server, how do you get same config as you have on your computer locally for like nvim or tmux

[chilly whale]

I don't change machines that often, so for me it's just manually cloning the repo with my settings

[spice hill]

class Foo(msgspec.Struct):
    banana_count: int = msgspec.field(name="banana-count")

class Foo(msgspec.Struct, rename="kebab"):
    banana_count: int

[chilly whale]

or repos, actually - I've got neovim and tmux configs in different repos

[wise imp]

mmm, that sounds useful and quick to sync, too, thanks

[ashen cipher]

:o ty!

[spice hill]

I would guess that defstruct is mostly intended for dynamically generating struct classes

[ashen cipher]

that seems to be the implication yeah

although TypedDict doesnt seem to work that way

[rain sail]

I m not getting what decorator is at all while creating class methods and how they can be used?

[spice hill]

Are you talking about specific decorators?

[rain sail]

I saw @classmethod in a code like this

            def how_many(cls):
                print("We have {} robots".format(cls.population))

But then the page where I saw this also said

Decorators can be imagined to be a shortcut to calling a wrapper function (i.e. a function that "wraps" around another function so that it can do something before or after the inner function), so applying the @classmethod decorator is the same as calling:

how_many = classmethod(how_many)

But then I wanna ask how can how_many.population possible

Btw the page is this https://python.swaroopch.com/oop.html

[spice hill]

Did you understand how a method marked with @classmethod is different from a regular method from the example?

[rain sail]

No and that's why I m confused

[spice hill]

Normal methods ("instance methods") allow you to ask something or change something about a specific instance of a class. But class methods are about the class as a whole. In the example, you can see that you can do Robot.how_many() -- that's operating on the Robot class, not any particular robot.

[rain sail]

Yeah and how do I use an instance method in class constructor?

[granite wyvern]

I'm not godly, but I've got a script called putacc which rsyncs my account to another machine with the --files-from option

[rain sail]

Self.method?

[granite wyvern]

If you're in the constructor (do you mean __init__?) you've got self.

[spice hill]

Yes, you can call methods on self inside __init__, just like in any other method.

[dry pike]

what does the cc stand for?

[rain sail]

Oh so I can create instance methods just inside init and if I m creating it outside then it's either a class attribute or a class method? But then why I needed the @ decorator?

[granite wyvern]

"acc" - put my account

[dry pike]

ah, not "puta CC"

[wise imp]

are you ungodly?

[spice hill]

I can create instance methods just inside __init__
No, where did you read that? Instance methods are not defined inside __init__.

[wise imp]

though you could

[granite wyvern]

Not... specificly.

[velvet trout]

super().__new__() ?

[velvet trout]

This gets boiled down all the way to C level to create instance right

[granite wyvern]

I suspect irrantional meant the initialiser, not the constructor

[rain sail]

I mean you also used the word init in ur earlier message can u tell why is it special in terms of instance method then?

[velvet trout]

[wise imp]

pretty sure __init__ is also referred to as the constructor

[spice hill]

I don't think I understand what you're saying

Maybe you could open a thread in #1035199133436354600?

[granite wyvern]

__init__ is just the name of the method Python calls on a new, blank, instance to initialise its stuff

[velvet trout]

its an initializer/setup though, not sure if calling it constructor would be appropriate

[velvet trout]

i would admit i used to think its the constructor

[granite wyvern]

Except that __new__is better referred to as the constructor. And __init__ is for initialisation 🙂

[velvet trout]

Until dunder new knocked on my door for his rights

dunder new is underrated fr

[brisk gazelle]

class Circle:
    def __init__(self, diameter):
        self.diameter = diameter

    @classmethod
    def by_radius(cls, radius):
        return cls(radius * 2)

circle_one = Circle(10)
circle_two = Circle.by_radius(5)
print(circle_one.diameter)
print(circle_two.diameter)```This is one use case for the classmethod decorator. Circle.by_radius becomes an "alternate" constructor here, another way of creating a Circle instance.

[spice hill]

I'm now realizing that A Byte of Python is a bad textbook if you're not already familiar with Java or another OO language and just need a crash course

[velvet trout]

everyone pays attention to the popular kid dunder init, thinking its the constructor. Meanwhile the real hero is dunder new, creating new instance object for you.

[rain sail]

Ikrrr but then how can I create an class method? And what's the role of decorator @spice hill

[spice hill]

It spends like 5 seconds on explaining what @classmethod does, and does it as part of a giant mega-example, mixing many things together.

[granite wyvern]

Pretty sure our friend fix is not, themselves, a decorator, even with the @

[rain sail]

Bro

[dry pike]

syntax error

[spice hill]

Since this is not a simple question, I'd recommend opening a post in #1035199133436354600, so that the conversation isn't lost in here.

[rain sail]

Aight

[velvet trout]

A decorator takes another function, wraps it and returns another function (usually).

@classmethod marks a function as a 'class method', meaning the function is callable without taking an instance but rather class itself as its first argument

[wise imp]

Pythonic is actually a glossary term 👀
https://docs.python.org/3/glossary.html#term-Pythonic

[rain sail]

Done

[inland karma]

good morning!

[spice hill]

Speaking of... does anyone know a good free resource that explains the basics of classes?

[velvet trout]

Ohayo gozaimasu, eivl!

[inland karma]

thats why we only and should only recomend it to someone that already knows one of those languages

[brisk gazelle]

def decorator(obj):
    return "Decorated thing."

def func():
    pass
func = decorator(func)

# being roughly equivalent to

@decorator
def func():
    pass

print(func)``````
Decorated thing.```@unsure.9

[rain sail]

What is a decorator a function? And it always starts with @?

[velvet trout]

OpalMist already cooked that answer for you

[inland karma]

a decorator is code that writes and changes code

[granite wyvern]

The @ introduces a decorator on a function, yes.
(There's also @ for matrix multiplication, but differently used.)

[velvet trout]

Transformation 😋

[wise imp]

it appears neither is actually itself a constructor according to the data model and the constructor is the call to the class itself??? it appears __new__ may be more appropriately referred to as a "creator"
https://docs.python.org/3/reference/datamodel.html#object.__new__

[rain sail]

So we are just passing a function in a decorator but why do we need to pass it any example?

[granite wyvern]

Yeah, probably. But calling __init__ the constructor is arguably wrong.

Anyway, we're splitting hairs.

[pallid garden]

why do you need to modify a function, you mean?

[rain sail]

Yeah...

[wise imp]

bikeshedding at its finest

[velvet trout]

The constructor is the call to the class itself???

type.__call__(MyClass) ?

[pallid garden]

one of the most common usage you will see is to declare that function as the handler for a URL/endpoint

[brisk gazelle]

I'm not sure I understand.

[wise imp]

MyClass(...) is seemingly what is the constructor (or at least the constructor expression)

[rain sail]

https://python.swaroopch.com/oop.html but why they used the decorator here? @brisk gazelle can I create a class method without using it?

[granite wyvern]

Yeah. My point is more that by the time __init__ is called the instance already exists. We're just polishing it off.

[spice hill]

Do you know of a good free resource that teaches user-defined classes? (something you can read after Automate the Boring Stuff with Python)

[pallid garden]

do you mean @classmethod?

[rain sail]

Ye

[wise imp]

yeah, that was just clarifying for Aji

[brisk gazelle]

That particular example could access that counter attribute through the instance, so it doesn't strictly need to be a classmethod there.

It could also access it explicitly through the class name itself.

Like it's doing elsewhere.

[pallid garden]

when you declare that the method is a classmethod, it receives the class as the first argument, the same way that the instance/object of a class gets passed as the first argument in an instance method

[granite wyvern]

Think of @staticmethod and @classmethod as describing the context the method receives. A normal instance method receives the instance, self. A class method receives the class. A static metho doesn't receive anything special as the first argument.

An instance method needs to be called from an instance: obj.method(....)
Because a class method provides just the class as context (the first argument, often called cls), you can call is via an instance obj.method() or via the class ObjClass.method().

A static method is just a function. Call it directly, call it via the class or call it via an instance.

[gilded herald]

remind me please, where can i throw in my code?

[rain sail]

Tyyyy

[wise imp]

pretty much anywhere you can put the raise keyword

[velvet trout]

Suppose this:

def deco(func):
    def wrapped():
           print("being called from wrapped() function.")
          return func()
    return wrapped

the deco is a function, which takes a function (func), and returns another function (wrapped) and the wrapped function returns the result of the original func function.

This is called the higher-order function. This is a kind of wrapping a function and adding a middle person.

def my_func():
     return "Hello, world!"

my_func = deco(my_func)  # this is what we call being decorated.
result = my_func()
print("Result:", result)

In blackjack, we can always think of aces as 11, unless it would cause a bust, in that case it would be 1. Total the hand and treat all aces like 11. If your hand busts, subtract 10 until your hand no longer busts or you're out of aces

[honest cradle]

        list_of_cards = self.hand.cards

        for card in dupe_list_of_cards:
            if card.value == "ace":
                ace_list.append(dupe_list_of_cards.pop(card))
            else:

it's ALWAYS 11 unless you bust

then it's 1

[white knot]

idk the game tbh

[swift sparrow]

that's it

[white knot]

ok

[honest cradle]

ok

i get that

[carmine skiff]

My neck is legitimately screwed multiple severe herniated discs

[swift sparrow]

ok, now we need to handle the bust

[honest cradle]

but i kinda have to keep track of aces tho

[swift sparrow]

if we're over 21 and we have aces in our hand, we can subtract 10

[turbid onyx]

Damn

[swift sparrow]

I already am in my example

[honest cradle]

like for the dealer

[swift sparrow]

no you don't

you just need a function that scores your hand

that's it

you don't score a dealer's hand until they flip their 2nd card

[honest cradle]

for soft 17

[carmine skiff]

Yup drunk drivers are a whole different breed of moron

[swift sparrow]

right now, this JUST scores the hand and nothing more

you can add another condition after to check for soft 17

[honest cradle]

yeah i get that

[swift sparrow]

"if score_hand(hand) == 17 and "ace" in dealer.hand.values:"

this is slightly pseudocode, but roughly like this

[honest cradle]

i get that

[swift sparrow]

we don't care if the hand is scored with an ace initially

don't try and do too much in a single function

keep them as simple and general as possible

[honest cradle]

wait hold on

[swift sparrow]

it's better to have 3 simple functions than 1 complex function

[honest cradle]

like say after i end my turn

does the dealer reveal his cards?

[swift sparrow]

the dealer only has 1 card to reveal

they are dealt 1 face down and 1 face up

[honest cradle]

but cant the dealer hit?

[swift sparrow]

yes, they MUST hit on <=16 or soft 17

[honest cradle]

that happens after my turn ends right?

[swift sparrow]

yes, once all players have resolved, the dealer goes

[honest cradle]

but the cards he hits are revealed?

ok that doesnt really matter in my code

move on

[swift sparrow]

that's it

after the players go, you reveal the dealer's hand and score it

you should know if the dealer has blackjack initially though

if the dealer is dealt blackjack, it ends

[honest cradle]

why

[swift sparrow]

everybody loses if the dealer is dealt blackjack

[honest cradle]

wait so my blackjack gets overriden by his one?

[swift sparrow]

unless you have blackjack too, then it's a push

[honest cradle]

elaborate

[swift sparrow]

push means tie

[honest cradle]

okayy

so we kinda dont need to knw tho

[swift sparrow]

you should keep track of the dealer's stuff internally even if the player doesn't have that information yet

[honest cradle]

why tho

its 1v1 blackjack

[swift sparrow]

so you know if they're dealt a blackjack

the player doesn't play out their turn if the dealer is dealt a blackjack

[honest cradle]

wiat what

[white knot]

how do i remove an added file from git

[swift sparrow]

1v1

I get dealt a card, dealer gets a card (face down). I get dealt another card, dealer gets another card (face up)

[honest cradle]

so they just get 2 cards and it s over?

[velvet trout]

🗿

[swift sparrow]

if the dealer's face up card is a 10 value, they peek at their face down card

[honest cradle]

woah i gotta completely nuke my game function

[swift sparrow]

if their face down card is an ace, the round automatically ends

if you ALSO have blackjack, you get your money back

otherwise, you lose

[velvet trout]

Don't nuke people, nuke code

- Alex

[honest cradle]

aight imma try to do something

[white knot]

i am writing my code in text editor now

its C code

[honest cradle]

were u writing it in notepad before?

[swift sparrow]

it also shouldn't be your player class that scores the hand

[white knot]

no vscode

[swift sparrow]

it's the game's responsibility to score the hand

[honest cradle]

my brother took 11th grade html in notepad

[swift sparrow]

treat your card/deck/player classes as if they could be used for any card game

[honest cradle]

it should be outside?

but my player class is only for my blackjack

[swift sparrow]

ideally you would have a Blackjack class

[honest cradle]

that is pretty much what it is

[swift sparrow]

sure, but when learning classes, it's a good idea to keep them as simple as possible

it should be a generic "player" class. It's something that holds onto cards

it's the game that gives those cards meaning

[honest cradle]

i have a hand class for that?

[quartz fulcrum]

how to convert the string like ''10 -20" into [10, 20]

[swift sparrow]

then what's the difference between player and hand here? If I were to make those classes, the Player class would also keep track of the money, have a name, etc

[swift sparrow]

with str.split

[ocean ridge]

serialize with str.split

[swift sparrow]

serialize?

[ocean ridge]

thats what u call it right

[swift sparrow]

this isn't the context I would use that term

[ocean ridge]

serializing a string to this array

[granite wyvern]

Tokenise. Kind of the reverse if serialise, in a way.

[swift sparrow]

I'd maybe say "parse"

[ocean ridge]

oh yeah

[honest cradle]

ig the player class is used to run somethings that will happen on both dealers side and players side

[granite wyvern]

Serialising is typically transcribing something to a string or bytes.

parsing/tokenising is the other way

[swift sparrow]

you could use the Player for dealer too, sure. Maybe add an attribute for "is_dealer" or something

[ocean ridge]

s = "10 -20"

parsed = [int(x) for x in s.split()]
print(parsed)

[golden mortar]

"Serialize" usually refers to converting some arbitrary object into a byte array, usually so you can store it or send it over a network

[ocean ridge]

yeah my bad i used the wrong term 🙃

[bronze dragon]

"deserialize" maybe
but that feels like too strong of a word for a .split lol

[velvet trout]

parsed = list(map(int, s.split()))

functional programming guys.

[quartz fulcrum]

what does map do

[swift sparrow]

calls a function on every element of another iterable

[quartz fulcrum]

i also hv to convert those numbers into int too

[velvet trout]

Takes a callable and an iterable, and passes each item from iterable to that callable

[swift sparrow]

data = ['a', 'abc', 'abcde']

let's say I have this list

and I want a list of all the lengths of these strings

can you tell me what that would look like @quartz fulcrum ?

[quartz fulcrum]

a loop?

[swift sparrow]

no, just what would the list look like

[velvet trout]

yeah, the map just makes it even easier

[swift sparrow]

instead of 'a', 'abc', 'abcde'

I want the len of these strings

[quartz fulcrum]

len(data)

[velvet trout]

Of each string

[swift sparrow]

no, that gives me how many things are in the list

[honest cradle]

    def score(self):
        aces = 0
        t_value = 0
        for card in self.hand.cards:
            if card.value.is_digit():
                t_value += int(card.value)
            elif card.value.lower() in ('king','jack','queen'):
                t_value += 10
            else:
                if t_value + 11 > 21:
                    t_value += 1
                else:
                    t_value += 11
                aces += 1```

does this work

[velvet trout]

You need to give the length of each item inside the list

[golden mortar]

Operators like map are typically used instead of a loop.

[swift sparrow]

no, we can't determine an ace will be 1 until after we've finished scoring the hand

we need to total the full hand, then we can retroactively correct the score if necessary

[honest cradle]

ok

    def score(self):
        aces = 0
        t_value = 0
        for card in self.hand.cards:
            if card.value.is_digit():
                t_value += int(card.value)
            elif card.value.lower() in ('king','jack','queen'):
                t_value += 10
            else:
                t_value += 11
                aces += 1
            ```

[golden mortar]

Though in Python list comprehensions and the like are more commonly used than map

[honest cradle]

boom

[quartz fulcrum]

no idea, i can only think of loop

[swift sparrow]

I'm just asking you what the list will look like in the end

I'm not asking you about any code

[quartz fulcrum]

ann int

[swift sparrow]

when you write code, you should know what result you're trying to achieve

[chrome isle]

Not quite. What if this sum is greater than 21 and you have an ace?

[velvet trout]

["a", "ab", "abc"]

Now create a list literal with each item's length, just type it yourself, not code.

[ocean ridge]

yeah thats the first thing that came to my mind

[swift sparrow]

if you don't know what the result will be, how can you write code to work towards that result?

[quartz fulcrum]

[a , ab, abc]

[golden mortar]

!e ```py
lst = [1, 2, 3]

loop

result = []
for x in lst:
result.append(x**2)
print(result)

map

result = list(map(lambda x: x**2, lst))
print(result)

comprehension

result = [x**2 for x in lst]
print(result)

oops

[swift sparrow]

why?

what's len('a')?

[edgy kraken]

[swift sparrow]

and len('abcde')?

[velvet trout]

Why do i feel like we are making wizard look like the python interpreter

[swift sparrow]

ok, so what would that look like in a list?

text = ['a', 'abc', 'abcde']

if I want the len of each of these strings?

[quartz fulcrum]

[1, 3, 5]

[swift sparrow]

yes exactly

[ocean ridge]

because we are-

[golden mortar]

A wizard larping as a Python interpreter? What has the world come to?

[swift sparrow]

text = [len('a'), len('abc'), len('abcde')]

we can think of it like this

but we can use map

[velvet trout]

Like his each output is exactly how in a REPL would be he ain't even putting words. Quiet straightforward result

[swift sparrow]

!e

text = ['a', 'abc', 'abcde']

print(list(map(len, text)))

[edgy kraken]

:white_check_mark: Your 3.14 eval job has completed with return code 0.

[1, 3, 5]

[swift sparrow]

mapping len to this list will give us that same result

[honest cradle]

aight

bt i think im gonna need to rewrite my game function for that

[olive sable]

hiiiii
what is map in this code

[velvet trout]

!doc map

[edgy kraken]

map

map(function, iterable, /, *iterables, strict=False)```
Return an iterator that applies *function* to every item of *iterable*, yielding the results. If additional *iterables* arguments are passed, *function* must take that many arguments and is applied to the items from all iterables in parallel. With multiple iterables, the iterator stops when the shortest iterable is exhausted. If *strict* is `True` and one of the iterables is exhausted before the others, a [`ValueError`](https://docs.python.org/3/library/exceptions.html#ValueError) is raised. For cases where the function inputs are already arranged into argument tuples, see [`itertools.starmap()`](https://docs.python.org/3/library/itertools.html#itertools.starmap).

Changed in version 3.14: Added the *strict* parameter.

[olive sable]

ohhh

[swift sparrow]

If you scroll up I just explained it above

[velvet trout]

.

[olive sable]

thansks

[quartz fulcrum]

ah ok...is it possible to map lists only>

[swift sparrow]

no, any iterable

!e

text = 'python'

print(list(map(str.upper, text)))

[edgy kraken]

:white_check_mark: Your 3.14 eval job has completed with return code 0.

['P', 'Y', 'T', 'H', 'O', 'N']

[quartz fulcrum]

so it will create a new list, always?

[velvet trout]

no, map returns a generator iterator

[swift sparrow]

it creates a "map" object

[velvet trout]

You can use any container which consumes that generator

[swift sparrow]

but I'm calling list() on it so you can see the result

[velvet trout]

tuple(map(int, my_list)) works too

[swift sparrow]

!e

text = 'python'

print(*map(str.upper, text))

[golden mortar]

Notably, the map object does not actually execute the mapping function until you consume it. Converting it into a list is one way of consuming it.

[edgy kraken]

:white_check_mark: Your 3.14 eval job has completed with return code 0.

P Y T H O N

[honest cradle]

btw

[spice hill]

(iterator, not a generator specifically)

[honest cradle]

im gonna need to make a computer computing function too

[velvet trout]

Oh yeah

i am too biased towards generator 🥀

Thanks for correction

[golden mortar]

I have to look up the definitions of the terms generator, iterator and iterable every time I need to use them.

[quartz fulcrum]

okk..

[spice hill]

that's definitely unusual

[ocean ridge]

[spice hill]

i thought it's pretty clear

[ocean ridge]

why do i share this problem too?

[golden mortar]

I'm exaggerating a little, but I do think they're easy to mix up.

I feel like I see a lot of other people having the same issue.

[swift sparrow]

they also overlap quite a bit

[velvet trout]

i call anything a generator which uses yield, iterator when its just implementing iterator protocol and iterable is any object returning an iterator

[swift sparrow]

it's like a square/rectangle problem

[velvet trout]

[quartz fulcrum]

yes

[velvet trout]

str() doesn't take iterable... Had to use "".join(...) broke my intuition/prediction as tuple/list/dict/set takes an iterable

[swift sparrow]

dict() takes a mapping

[velvet trout]

Yeah right

though its intuitional

[gleaming knoll]

it works with both by checking if it has keys&getitem and then iterable

[velvet trout]

russia has a great memory

[swift sparrow]

isn't that a mapping just in more words

[velvet trout]

I ain't putting a print bro

[white knot]

what was the advantage of switch statements over chained if-elif

[swift sparrow]

matching shape

[velvet trout]

match-case*

!pep 636

[gleaming knoll]

keys&getitem are the same kind of mapping as what you need for **kwargs but not sufficient for collections.abc.Mapping, and dict([(1, 2)]) works even though it doesn't have keys

[swift sparrow]

yeah, mapping is pretty loosely defined in regards to what dict wants

[honest cradle]

ok so

in blackjack

1v1

i get a turn and the dealer gets a turn right?

so when is it scored

[swift sparrow]

it doesn't alternate

the player goes first and hits (asks for cards) until they stand (no longer want cards)

if the player busts, it just ends there

[honest cradle]

so i just rewrote my logic for no reason

[past wave]

Is it just me or OOP is a little bit hard haha

[swift sparrow]

if the player stands with a value of 21 or less, then the dealer takes their turn

[swift sparrow]

It's a pretty big jump in complexity and kinda reframes how you have to think about things

[golden mortar]

Most programming concepts are difficult when you first encounter them.

[past wave]

So I need to be scared, fu*k -.-

[golden mortar]

OOP is also a big area

[swift sparrow]

why be scared?

[golden mortar]

There are parts of it that are harder than others

[wise imp]

OOP is a hoax anyway /hj

[spice hill]

Well... str() does accept iterables as the first argument...

[swift sparrow]

We all figured it out eventually, you can too

[swift sparrow]

yeah it just calls the __str__ of that instance

[golden mortar]

No, you shouldn't be. It's difficult at first, but it gets easier as you get more familiar.

[honest cradle]

https://paste.pythondiscord.com/BE2A

@swift sparrow this isnt finished

but am i on the right path

[swift sparrow]

the score function?

[honest cradle]

everything

check out my game function

[rain sail]

best way to use free ai forever in pycharm?

[swift sparrow]

you can't really have a bust function without a score function that works

whenever the player hits, you'll score their hand

[rain sail]

i have student developer pack still cant get it./

[honest cradle]

wdym

[swift sparrow]

you have a value function and a score function and I don't understand why you have both

just get the scoring function working first, then you can continue

you nearly have it

let's say for example the hand is 6, king, ace

we go through first scoring everything (with ace as 11) and we calculate 27

6 + 10 + 11

after we score, we can say "if we have over 21, but we scored an ace, then subtract 10"

[honest cradle]

my scoring does that

[velvet trout]

Huh

[swift sparrow]

no it doesn't

it handles the first part

not the corrective part

[velvet trout]

I mean in a sense it doesn't consume its items to write a string of those items. It just calls dunder str of that object

Like how tuple & list consumes items and creates a tuple/list container of the given object

[past wave]

Im learning from course, and she said that we're gonna use big guns now haha

[swift sparrow]

sounds pretty reasonable that str() would call the object's __str__

[past wave]

Yeah, I understand what you wnat to say

[velvet trout]

Yeah, indeed

does it have anything like str.from_iterable(iterable) ?

[swift sparrow]

nope

[velvet trout]

I could only think of using "".join(iterable) at the moment.

[swift sparrow]

basically join

[bronze dragon]

str.join is what you want

[swift sparrow]

assuming the iterable contains only strings

[velvet trout]

str.join does call dunder str of the items consumed from iterable, right?

[swift sparrow]

no

[bronze dragon]

str.from_iterable as you describe it could only be a less-general (and less-useful) version of str.join

[bronze dragon]

no, the iterable needs to be made of strs in the first place

[swift sparrow]

you couldn't ''.join(range(5))

[velvet trout]

Oh yeah that's why i also do map(str

[bronze dragon]

, iterable)

[velvet trout]

HEHEHE

[swift sparrow]

@honest cradle sorry I gotta go but you're nearly there!

good luck
