so much code golfing

[split salmon]

@humble rune

look at this: https://github.com/AFK-debug-9/test

[humble rune]

not poggers

those programs are super long

😔

@humble rune that breaks discord TOS

[near gust]

you can change a type's __dict__ by writing to id(obj) + 264

however, when using __dict__ directly it'll always convert to a mapping_proxy

[earnest wing]

You can still mutate elements pointed to by mapping_proxy thanks to a cpython bug

er there was a demo here a couple times I think, hold on

Here's one I think

[near gust]

I think you would need write to id + 248 to disable this behavior

tp_getset or whatever it was

specifically changing it to a null pointer

or changing the __dict__'s entry in the table

[rugged sparrow]

if you null out tp_dict it will crash when using the type

replacing it can also have weird effects

!e ```py
def getdict(cls, E=type('',(),{'eq':lambda s,o:o})()):
return cls.dict == E

getdict(int)['bit_length'] = 42
print((1).bit_length)```

[night quarry]

@rugged sparrow :white_check_mark: Your eval job has completed with return code 0.

42

[rugged sparrow]

^ that works too

[near gust]

I was just trying to mess around and make a metaclass that isn't an instance of type so it can have a custom __dict__ that isn't a proxy and then I ended up messing around and reading cpython source code

[swift trench]

i wounder how can such code work...

[rugged sparrow]

#esoteric-python message here is when i worked through why that bug exists

[near gust]

however without ctypes, you'll be guaranteed to run into errors about your metaclass not being a class, and then that leads your own object class

[swift trench]

what this code is supposed to compute?

[rugged sparrow]

it exploits a bug with how mappingproxies work, and uses it to get the int types internal class dictionary

[swift trench]

Impressive!

you're trying to write to read from stdout.

[short crag]

yeah..

thought r+/w+ supported read and write?

[signal herald]

sure, but stdout doesn't.

stdout is write-only.

[short crag]

how can I get input then?

[signal herald]

stdin

open(0, 'r')

lemme try

if([_:=(...)],[__:=({_}|{_})]):{(lambda:exec("open(1, 'w').write('Result: '+open(0, 'r').readline(1))"))()};

thinking readline is only catching the first part

what am I doing wrong here

from ctypes import *
from time import *
tm = POINTER(c_int * 10).from_address(

  const char *tm_zone; /* Timezone abbreviation.  */
};```

int _PyTime_gmtime(time_t t, struct tm *tm);```

typedef long int __time_t;      /* Seconds since the Epoch.  */```

probably a lot wrong but I'm mostly like to not crash

[rapid sparrow]

nice exec from a lambda

[quartz wave]

shouldn't you do malloc(sizeof(c_int) * 9 + sizeof(c_long) + sizeof(c_char_p))

[rapid sparrow]

oops, probably yeah

that far still works 🥳

>>> tm                                                                      <__main__.LP_c_int_Array_10 object at 0x5555cc3e40>```

[quartz wave]

also doesn't tm_zone have to have a value or something

[rapid sparrow]

hmm

it crashes in PyCPointerType_paramfunc for my
(gdb) p obj $1 = <LP_c_int_Array_10 at remote 0x5555ae19a0>

-->>       parg->value.p = *(void **)self->b_ptr;```

lemme see if I can figure out how to initialize that field

oh crap

self.b_ptr is
b_ptr = 0x55b2edf0 <error: Cannot access memory at address 0x55b2edf0>,

I guess it's not a valid pointer to memory

maybe I need two allocations?

like I need to actually allocate space for the pointer

?

[quartz wave]

probably

or you can create a struct using Structure

[rapid sparrow]

now I think you were onto something

>>> st = c_size_t(addressof(tm))
>>> PyDLL("")._PyTime_gmtime(c_uint(int(mktime(gmtime(0)))), st)            Reading in symbols for offtime.c...

52        tp->tm_wday = (4 + days) % 7;```

[rapid sparrow]

thatd be the better way, I would need to read the values eventually anyway I guess

there is struct_time in the time module but I wasn't sure if I could use that

yes my tp is pointing to invalid memory apparently
(gdb) p tp $1 = (struct tm *) 0x55b2edf0 (gdb) p tp[0] Cannot access memory at address 0x55b2edf0

I didn't don't know it was gonna be this hard to make one call 😂

definitely gives me an apprefciation for the volumes of C code

that does not work as you forgot to take into account that (old_vy - 0.08) * 0.98 is supposed to be the vy in abs(vy) >= 0.005

do @wheat river's solution ```py

whats this and None used for?

[quartz wave]

discard the resulting unneeded list

.argtypes isnt 100% required, but otherwise ctypes will attempt to guess converters (and that can fail on some builds)

[finite blaze]

What does the * do in print(*fizzshit(100))?

[wheat river]

its for unpacking an iterable

so in case of

print(*[1, 2, 3])

it would look like

print(1, 2, 3)

it like fills the args when u do it inside a function

u can use ** to do the same but for kwargs

[finite blaze]

Ooh

Thats super cool

Good for golfing

I don't have to use for loop to print my list

[earnest wing]

star unpacking is useful for all sorts of golfing

for example, [*iterable] is shorter than list(iterable)

No, it works fine in python, just interesting that the )or is a syntax error in Xonsh, it is lateral to python

[humble rune]

hm

xonsh wont tolerate my code golfing antics

any fellow code golfers who want to share golfed code?

i would be very happy

[primal idol]

for i in range(1,101):print("Fizz"*(i%3==0)+"Buzz"*(i%5==0)or i)

One char shorter xD

[humble rune]

yooooo

niceeeee

[primal idol]

You can go down to 59, but that is beyond me

[pastel sparrow]

the ==0s are redundant though

or am i tripping

[earnest wing]

the first step is to reduce to

i=1;while i<100:print("Fizz"*(i%3==0)+"Buzz"*(i%5==0)or i);i+=1

[primal idol]

!e

for i in range(1,6):print("Fizz"*(i%3)+"Buzz"*(i%5==0)or i)

[humble rune]

its to check if its divisible by 3 or 5

[night quarry]

@primal idol :white_check_mark: Your eval job has completed with return code 0.

001 | Fizz
002 | FizzFizz
003 | 3
004 | Fizz
005 | FizzFizzBuzz

[earnest wing]

of course you can also turn ==0 to <1

[humble rune]

good idea

[primal idol]

Isnt that is a syntax error?

[lusty sinew]

for i in range(100):print(i%3//2*'Fizz'+i%5//4*'Buzz'or-~i)

[humble rune]

dayum we code golfing today

59 fucking chars

niceeee

[humble rune]

wait what the fuck?

why does -~ add 1

my brain hurts

[lusty sinew]

~ reverses all bits

for ints its the same as (-x) - 1

then invert it again with -

[earnest wing]

that should be the optimal

at least if I remember the cgcc submission correctly

[humble rune]

ohhhh damn

hm

why does it subtract 1 tho

im confused

eh

it just works i guess

[wheat river]

for i in range(100):print('FizzBuzz'[i%~2&4:12&8+i%~4]or i)

whats λ?

[west cipher]

lambda shorthand

λ(x**2)(5) = 25

[finite blaze]

λt is for map

[quartz wave]

https://paste.pythondiscord.com/kizoxelaja a few more lines of code to make it more performant (untested)

[lone sphinx]

I actually did update it a bit.
https://paste.pythondiscord.com/fokivirova.py

You can chain as many sync or async methods/attrs as you like, then await it at the end.

I also made a decorator to help with __await__()

def async_await(func):
    @functools.wraps(func)
    def decorator(*args, **kwargs):
        return (yield from func(*args, **kwargs).__await__())

    return decorator

[astral rover]

what about adding support for nested awaits await (await asyncio.sleep(0, result=asyncio.sleep(10)))?

[lone sphinx]

out of scope

this is just fluent async

if condition1 or condition2:

if condition1or condition2: #will only work if the character before the OR is a ", ', a number, or any other thing like ( or [

if condition1+condition2:

[quartz wave]

if ~condition:
``` only works if `condition` is `False`/`0` or `-1`

[lunar moon]

oh yeah ur correct my mistake ~-condition shud work, but welp it doesn't reduce the characters

[icy frigate]

like print for example

[finite blaze]

p=print

You mean something like this?

Then you can do
p("1")
For example

[formal sandal]

Does anyone miss postfix await from Rust and how it lets you chain methods nicely? You can easily have it in Python:

    (sleeper
        .sleep(1)[await ing]
        .sleep(2)[await ing]
        .sleep(0.5)[await ing]
    )

asyncio.run(main())

ohh

im stupid

[sick hound]

i did it but its too long

[shell brook]

I hate this

[sick hound]

i could make it better but dont want to

[sturdy rune]

looks like base64 at first

[sick hound]

it just takes a normal string and turns each letter into bytes then creates a randomized string with that amount of letters (the byte number) and does len() to turn it back to bytes

try: open('obfuscated.py','x') 
except: pass

code = "print('Hello World!')"

import string
import random
import codecs

print('exec(str(', end='')
for letter in bytes(code,'utf-8'):
    line = ''.join([random.choice(string.ascii_letters) for _ in range(letter)])
    #print(f'len("{line}")+', end='')

    print(f"codecs.decode(len('{line}').to_bytes(1, byteorder='big'))+", end='')

print('""))', end='')```

here the code its really simple

ignore the top part

its NOT a good obfuscation method to protect your code, its just funny to look at

you can rearrange a little and get -2 chars:

root=lambda f,x=1,k=1e-9:(-k<(r:=x-f(x)*k/(f(x+k)-f(x)))-x<k)*r or root(f,r)

[fleet bridge]

it isnt true in general
iter(aa) can have side-effects

[wispy wedge]

Maybe there's some background thread whose behavior heavily depends on the execution speed of this function 🤔

[finite blaze]

Anyone here ever tried writing terminal chess

and then golfing/one-lineing it?

[pastel sparrow]

wait what side-effects

[rugged sparrow]

it calls aa.__iter__

you could theoretically pass an object that mutates itself when __iter__ is called

[dark wharf]

Even in the example, if you'd used fishhook and modified list iter you wouldn't get the same result from your new lambda

[earnest wing]

Code analysis should not have to assume builtin immutable types are mutable, so that's a little moot.

[finite blaze]

Hey,
I once asked what and None meant in this code:
type=lambda w:[y:=0,vy:=.42,[[print("tick n°",i,"| Y speed:",vy,"| Y position:",y),y:=y+vy,vy:=(0if abs(vy:=(vy-.08)*.98)<.005 else vy)]for i in range(w)]]and None

and someone told me:
discard the resulting unneeded list

What does that mean?

why I have to do this?

[next flame]

it's so that the function return None instead of a junk list (that's only used to sequence operations)

so i'm pretty sure you're referring to [bb for bb in aa]?

oh wait i just realized a bug in HasChanging

[sly flume]

hi i'm know in python i'm take some basic thing about list and tuple but my not full understand the my cod i want create list have three index in each index have tuple with tow index like this [('a','b'),('b','c'),('c','d')] the first index in tuple have tow char or the length context when have like this [('~a','a'),('ab','b'),('bc',' c')] can any one help my ? The sample out put the my code

---

def getNGrams(wordlist, n):
ngrams = []
padded_tokens = "~"*(n) + wordlist
t = tuple(wordlist)
for i in range(3):
t = tuple(padded_tokens[i:i+n])
ngrams.append(t)
return ngrams

Just i need to specific index 0 in tuple to take one or tow or any number of char depending on ngram

Can anyone help me 🙏🏻

[wheat river]

:0

[vestal cedar]

For the sake of making and example, that turns into:

function=lambda a,b:(('4','7')[(a+b)*8>2**(a+b)],a)

gfg exaplains it pretty good: https://www.geeksforgeeks.org/ternary-operator-in-python/
Basically, you have a tuple of two elements ('4','7'). You know you can access the '4' by doing ('4','7')[0], and same with seven, right? ('4','7')[1]
Then, you can do this: ('4','7')[my_condition], why? Well, indexes are ints, when you cast a bool to an int, you get: false -> 0, and likewise: true -> 1.
For instance, imagine my_condition = true, then ('4','7')[my_condition] -> ('4','7')[true] -> ('4','7')[1] -> '7'

[quartz wave]

i know that

but for the sake of side effects i won't do that

thanks to @viral rose for helping a bit with this btw

not really the most efficient script though since it iterates over every number in the range twice but it's still pretty good

how it works is it makes a list for every number containing all the valid words and then it iterates over all of those outputs again, checking if each one is an empty list and replacing it with the number if it is

[viral rose]

this channel just made my brain explode

[severe canyon]

you can make it a bit shorter :)

d = {3:"Fizz", 5:"Buzz", 7:"Fuzz"}
print(*[''.join(d[k]for k in d.keys()if i%k<1)or i for i in range(1,101)],sep='\n')

[lethal cradle]

ooooooo

i didn't know you could use or in that way in python

[severe canyon]

if the string is empty, use the integer value

[next flame]

that only works if strs are same length

xor=lambda t,k:"".join(chr(ord(a)^ord(b))for a,b in zip(t,k*len(t)))

[next flame]

you can make it even shorter 😉

d={3:"Fizz",5:"Buzz",7:"Fuzz"}

kek i have a 59 char one
for i in range(100):print(i%3//2*'Fizz'+i%5//4*'Buzz'or-~i)

me after violently golfing my code so much i dont know what does what anymore

😎

this is a relatively simple golf

def xor(a,b):
    c,d,e=[*map(ord,b)],[],-1
    for i in[*map(ord,a)]:exec("e=[-~e,0][e>=len(c)-1];d.append(i^c[e])")
    return "".join([*map(chr,d)])

its slightly readable

def xor(a,b,d=[],e=~0):
    c=[*map(ord,b)]
    for i in[*map(ord,a)]:exec("e=[-~e,0][e>=~-len(c)];d.append(i^c[e])")
    return "".join(map(chr,d))

149 chars

def xor(a,b,d=[],e=~0):
    c=[*map(ord,b)]
    for i in[*map(ord,a)]:e=[-~e,0][e>=~-len(c)];d.append(i^c[e])
    return "".join(map(chr,d))

this works apparently?

141 chars

def xor(a,b,d="",e=~0):
    c=[*map(ord,b)]
    for i in[*map(ord,a)]:e=[-~e,0][e>=~-len(c)];d+=chr(i^c[e])
    return d

my take on the string obfuscator: ```py

plainstring = "Hello World!"
cipherstring = '"".join(map(chr,'

def f():
return choice([True, False])
def g():
return choice([">", "<", "^"])

chars = list(map(ord, plainstring))
cipherchars = []

for c in chars:
intermediate = []

while c != 0:
    res = f"(({f()}{g()}{f()}{g()}{f()}{g()}{f()}){g()}{f()})"
    c -= eval(res)
    intermediate.append(res)

cipherchars.append("+".join(intermediate))

cipherstring = cipherstring + str(cipherchars).replace("'", "") + "))"

you'll never get the same output for the same input

[pastel sparrow]

you can use isinstance too

[thorny tapir]

oh right

v = [1, 2, 3]  # variable

Technically you could do py print(type([]) is list)

[fleet bridge]

[].__class__ is list

[icy wing]

I need to print out comma-separated contents of a list that can take two possible forms. Either ['label', value] or ['label', [values]]. So, for instance, I would need to output label, value or label, val1, val2, ..., valn. I think this is possible with one statement but my previous attempts have run into typing issues. Any ideas?

theres a bunch... and they are testing for python 3.5 (???) despite being in a 3.9-specific location

perhaps a way to gain some startup speed 👀

That's probably because they are relying on 3.5+ specific behaviour of importlib.util.module_from_spec and importlib.machinery.PathFinder.find_spec

no

ok idk probably caused by an unhandled KeyboardInterrupt

[rich hound]

uhh

i have try/excepts tho

[earnest wing]

Very nice

[quartz wave]

like what's the full error you encountered

before the Current thread ... stuff there should be a Fatal error message or something

[rapid sparrow]

does it abort if there's a KeyboardInterrupt while an exception is pending ?

[quartz wave]

usually everything aborts when a KeyboardInterrupt happens

[rapid sparrow]

like terminate your program completely ?

[quartz wave]

not really

python probably just comes out with a KeyboardInterrupt message

[rapid sparrow]

java will do so if two exceptions are thrown at once , I think

[quartz wave]

the real cause could be a function returning a non-null value with an unhandled exception

or a function returning a null value with no raised exceptions

[rapid sparrow]

oh yeah, that is true

sometimes it tells you that, I'm not sure when it's able to raise a SystemError and when it isn't

I guess the test would be to return 0 from some function with an exception is set

[rich hound]

does it help that i had threads

[rapid sparrow]

!e well this didn't have the intended effect but I thought it was funny anyway

import ctypes as c
