it took 700 MB before I ctrl-c'ed it

def b(o):
   import time
   t = 0
   while True:
     print(id(o))
     try:
       o.__call__
     except AttributeError:
       return t
     o = o.__call__
     t += 1
     time.sleep(0.25)

shows that the ids of __call__ aren't the same

literally infx objects in python functions

flawr

what the heck are you guys doign?

Downgoat

@noɥʇʎPʎzɐɹC What is the self attribute in functions in the global scope?

noɥʇʎPʎzɐɹC

@flawr I just showed that all python functions have a __call__ attr and they themselves are functions

Maltysen

@Downgoat in global scope?

flawr

so python functions == objects?

noɥʇʎPʎzɐɹC

23:05

@Downgoat self is just a name - you can call it potato, the system just does class.member_function(instance, arg1, arg2) when you do instance.member_function(arg1, arg2)

Downgoat

@Maltysen yes

noɥʇʎPʎzɐɹC

@flawr yes

Maltysen

@Downgoat normal functions outside of a class shouldn't have self attribute

Downgoat

PyObject*s are initalized with (PyObject *self, PyObject *args)

Maltysen

@flawr python everything == objects

noɥʇʎPʎzɐɹC

23:06

@Downgoat It's just a normal argument, self is just the standard

@Downgoat that means (Class *self, PyObject *args)

Downgoat

@noɥʇʎPʎzɐɹC also is there a way to get all the keys of a python object. Like even the hidden ones (like __foo__)

Maltysen

@Downgoat dir

Downgoat

that returns dictionary no?

Actually that might work

Maltysen

@Downgoat no

Downgoat

sweet thanks

noɥʇʎPʎzɐɹC

23:11

import time
o=int
while 1:print(id(o));o=o.__call__;time.sleep(0.001)

Maltysen

@Downgoat anyways, doing list() on a dict returns its keys

noɥʇʎPʎzɐɹC

for a counter in python

Downgoat

what attribute is an integer's value stored in?

noɥʇʎPʎzɐɹC

@Downgoat there is no way, attributes can be dynamically returned

Maltysen

@Downgoat what do you mean by value?

noɥʇʎPʎzɐɹC

23:13

like I could make an object that returns "pizza" for all attributes

@Downgoat int is implemented in c, so there is none

Maltysen

@noɥʇʎPʎzɐɹC yes, but dir returns the ones registerd with __getattr__

Downgoat

Hm okay

can you give me a list of all primitive classes?

noɥʇʎPʎzɐɹC

@Maltysen you mean __dict__

@Downgoat primitive classes?

Maltysen

@noɥʇʎPʎzɐɹC i meant __getattribute__

Downgoat

@noɥʇʎPʎzɐɹC okay, another question: Is there a way to get { k: v } dictionary of an object?

I tried dict(foo) but that returns error if foo is not iterable

Maltysen

23:16

@Downgoat .__dict__

noɥʇʎPʎzɐɹC

@Downgoat type is the only object with a special property, which is it being it's own type

@Downgoat .__dict__

doesn't work for dynamic attrs though

Downgoat

@noɥʇʎPʎzɐɹC like classes which have their values as C++ items

e.g. int, string probably

noɥʇʎPʎzɐɹC

@Downgoat there are tons

El'endia Starman

@Downgoat {y: x.__getattribute__(y) for y in dir(x)} works in Python 3.

Maltysen

@Downgoat you might just want the builtin types

El'endia Starman

23:18

(I may have taken you too literally.)

Downgoat

@Maltysen yes those ones

Maltysen

docs.python.org/3/library/stdtypes.html

@Downgoat note that a lot of theses aren't "primitive" in the sense you meant

e.g. range

noɥʇʎPʎzɐɹC

some of those are implemented in python, not c

There are a few objects with the special property of not being able to inherit off of them, for edge cases such as bool

also for singletons, like ...

El'endia Starman

...I'd honestly forgotten that ... are a thing in Python 3.

>>> print(...)
Ellipsis

I don't know/remember what they're used for.

Maltysen

@El'endiaStarman I love using it instead of pass

TuxCopter

23:26

@El'endiaStarman Nothing, can be used for AST rewriting magic or placeholders

Maltysen

@TuxCopter it was intended for numpy slicing

TuxCopter

Well, in vanilla Python it do nothing

Downgoat

@El'endiaStarman waaat

TuxCopter

Welp SVG arcs are weird

Downgoat

Is numpy written in python or c++?

TuxCopter

23:34

C++ ~~probably~~ definitively, because performance and strict typing of numpy

TuxCopter

23:51

ಠ_ಠ I made an handmade SVG, I edited it in Inkscape to modify a path, now the file is totally messed up

El'endia Starman

Yeah, numpy is definitely not written in Python.

It's meant to be super fast at stuff like array manipulation.

Ultimatum game

The ultimatum game is a game in economic experiments. The first player (the proposer) receives a sum of money and proposes how to divide the sum between the proposer and the other player. The second player (the responder) chooses to either accept or reject this proposal. If the second player accepts, the money is split according to the proposal. If the second player rejects, neither player receives any money. The game is typically played only once so that reciprocation is not an issue. == Equilibrium analysis == For illustration, we will suppose there is a smallest division of the good available...

@El'endiaStarman list slicing

and .pyi files, and for elegance, ... can be valid python code

Kavka's toxin puzzle

Kavka's toxin puzzle is a thought experiment about the possibility of forming an intention to perform an act which, following from reason, is an action one would not actually perform. It was presented by moral and political philosopher Gregory S. Kavka in "The Toxin Puzzle" (1983), and grew out of his work in deterrence theory and mutual assured destruction. Kavka is also well known for his Paradox of Future Individuals, which addresses our moral obligation to future persons to plan for the future now. His slave child example also displays the deontological concept that holds humans as "beyond...
