but it's gotta be in the frame code
broken mesa
not the frame, but the ast definitley
floral meteor
ast? even better i spose
broken mesa
!e ```py
import ast
a = ast.parse("""
from typing import List
List[int]
""")
print(a.body[1].value.slice.id, a.body[1].value.value.id)
night quarryBOT
@broken mesa :white_check_mark: Your eval job has completed with return code 0.
int List
neat
@floral meteor thats how you could get it using ast
but if you can get the actual return of List[int] (or any subscriptable typing) you can just look up the args from that object
earnest wing
@floral meteor what you actually want does work with ast, you just need to access .target and .annotation
unfortunately you do need to either use string literals or custom encodings
@broken mesa I believe the question is how to access the annotation in foo[bar]: something
earnest wing
In [12]: a = ast.parse("list[int]: expr")
In [13]: a.body[0].target
Out[13]: <ast.Subscript at 0x10aa676a0>
In [14]: a.body[0].annotation
Out[14]: <ast.Name at 0x10b8c7f40>
!e ```py
from typing import List
a = List[int]
print(a.args)
@broken mesa :white_check_mark: Your eval job has completed with return code 0.
(<class 'int'>,)
this is the way to do it if you were to make it a custom type, and have access to the return value
i used List as a example, can obviously be a custom subscriptable typing
anyways, i gotta sleep

hmmm

The type(a) is to get the function type, which is initialised on the same code as a, except with its name replaced.
It makes a new function from scratch, out of the old one.

There's many different activities that fall under the category of esoteric coding.
for example, code golf is achieving code in minimal characters.
while brainfuck is a minimalist Turing Complete interpreter.
essentially, the core theme is either challenge, gore, or art
if ur using google translate ur probably getting wierd stuff like blood and occupations. idk im not exactly multilinguist
floral meteor
yeah
Есть много разных занятий, подпадающих под категорию эзотерического кодирования.
например, код гольф - это код, состоящий из минимального количества символов.
в то время как brainfuck - это минималистский интерпретатор Turing Complete.
по сути, основная тема - вызов, кровь или искусство.

it calls the __mod__ method of the left side, with the right side as the argument.

jk y'all get the idea of what it does, tho, right?
y'see I used . as a variable name?
only this channel could produce something as twisted as that
rugged sparrow
you know i might be able to write code that makes locals()[name] = value actually work
acc i prob could yea
floral meteor
if you could find a way to access locals() non-locally that would be great :>
snow beacon
It has been tried in the past.
rugged sparrow
well it would require that the name name exists in the code
@snow beacon i can access the fastlocals array manually
floral meteor
wait, can't you do it with exception catching?
something like
def funcy():
a=4
try:raise Exception
except Exception as e: return e.__traceback__.tb_frame.f_locals
globals.update(funcy())
print(a)
```?huh. what if...
floral meteor
!e ```py
a=3
def wow():
a=4
def mucherror():
a=5
raise Exception
try: mucherror()
except Exception as e: print(e.traceback.tb_frame.f_lineno); return e.traceback.tb_frame.f_back.f_locals['a']
print(wow())
well I can access the locals of the previous frame, but that can already be done by the namespace, iirc
rugged sparrow
@floral meteor making locals() assignable has more issues than i forsaw
floral meteor
uh oh
rugged sparrow
yea cause any names that arent assigned to in that scope use LOAD_GLOBAL
(so messing with locals does nothing)
floral meteor
pycharm has r colouring 0o0
I prefer my much more explicit namespace regime
everything comes from globals
snow beacon
Myself I like adequate scoping, which is very difficult in Python.

I'm pretty sure the Nones are related to exceptions thrown inside the with.

If your object has __enter__ and __exit__ then it is said to 'implement the context manager interface,' yes I know it's for using with a with statement, I'm trying to understand what it was intended to be used for, given that it didn't seem to be used in the example.
floral meteor
I was starting to try to find a work around for another usage for the int statement in c++
with int(2,3) as n, m:
cout << n << " " << m << " are your integers"
Ah, ok, I had literally never seen that c++ syntax before. so I didn't recognize what syntactic sugar you were implimenting.
floral meteor
since you can't really do
int n m
int() {
cout << "give two numbers> "
cin >> n
cout << " "
cin >> m
cout << n << " " << m << " are yer numbers"
return n m
}
Right.
floral meteor
so a python context manager is the best I could come up with for allowing an indented code block
also, in cout, '__repr__':lambda s:"\n" otherwise, you do the printing to cout in terminal it will append <__main__. function>
snow beacon
also, in cout, `'__repr__':lambda s:"\n"` otherwise, you do the printing to cout...
Methods are passed self as their first argument. Maybe you meant to ignore that argument?
vague cairn
nods a while ago I managed to implement cout << in a way I liked, mostly because I was trapping and reassigning output and debugging messages anyway, and figured why not. Then for completeness sake I went to try the same with cin >> and realized the thing I had just about stopped worrying about, everything passed by reference means, actually nothing is... I went messing around with various things, including decorators and re-compiling, until I realized that someone else had already done that better.
I like what you've done here to implement that, and that it only needs objects to to know their own __name__ the only thing I can think of to give more reliable results would require disassembling the calling frame's code object, which would be a lot of extra work. At which point, is there a way to interact with locals instead of globals?
Anyway, good job, etc.
Lately my preferred debug output trapping pattern has been:
DEBUG = print
class c:
def __init__(self, [normal stuff], log=DEBUG):
#normal stuff
self.log = log
def do_some_work(self):
self.log("starting some work")```
eventually, after I finish implementing and testing the module, I replace the first line with ```DEBUG = lambda *a, *k: None```
And still retain the ability to turn on debugging messages for specific instances of the class by initializing them with `log=print `noice
code i make isn't debuggable
it's just code puke
if it doesn't work, that's unfortunate
vague cairn
shrug I usually try to make it readable while I'm figuring out how to implement it, I can shrink cut out unnecessary bits and golf it later.
snow beacon
i used s so it doesn't complain about too many arguments passed
I wasn't meaning the __repr__ method, I meant however it's getting printed. (I can't see the code.)
floral meteor
it's already printing stuffs, but the trailing expression after a chain of << will repr in the terminal as self.repr hence i want the trailing expression to repr as a newline
so it prints all the stuffs, then evaluates the repr and starts a new line
snow beacon
Ah, I understand.

yeah, the two most basic tips in golfing are:
- use short (ideally single-character) variable names
- avoid unnecessary whitespace (which there is actually a lot of where you wouldn't expect it in ungolfed code)
also, def f():return can be shortened into f=lambda:

fair shell
Where can I find the code-under-the-hood for python's amazing a, b = b, a feature?
earnest wing
b, a is just sugar to construct a tuple (b, a).
a, b = x is a destructuring assignment that iterates over every element of x, and tries to assign the first & second elements to a and b. (It also raises when there's the wrong amount of elements to unpack in x.)
Together, you constuct a tuple of b and a, then assign a and b to the first & second elements of the tuple you constructed.
fair shell
Ah, very cool. Thanks Olivia.
earnest wing
You can also do cool nested destructurings like
a, (b, c), *rest = x
And to get the first element of a list with one element, you can do a ,= [b].

cloud fossil
I already solved this exercise and thought I should share:
The challenge was to make the following function without + nor list.extend() nor loops:
def extend_list_x(list_x, list_y):
pass # should return [1, 2, 3, 4, 5, 6] for list_x=[4, 5, 6] and list_y=[1, 2, 3]
So, my unpacking solution was this:
def extend_list_x(list_x, list_y):
return [*list_y, *list_x]
and my recursion solution was this:
def extend_list_x(list_x, list_y):
temp_list = list_x[:]
if len(list_y):
temp_list.insert(0, list_y[len(list_y)-1])
return extend_list_x(temp_list, list_y[:-1])
return temp_list
So my question is: Can you guys think of any other way to do it?
hard spoke
def extend_list_x(list_x, list_y):
lst = []
lst[:] = list_x
lst[len(lst):] = list_y
return lst
🙂
can make the first two lines lst = list_x.copy()
cloud fossil
ahh
your function actually outputs [4, 5, 6, 1, 2, 3] though
but ye you can just copy the other thing
hard spoke
your function actually outputs `[4, 5, 6, 1, 2, 3]` though
no it doesn't
cloud fossil
😐
hard spoke
oh, it's supposed to be in the other order
cloud fossil
ye
hard spoke
okay then,
def extend_list_x(list_x, list_y):
lst = list_y.copy()
lst[len(lst):] = list_x
return lst
i originally intended these to change list_x
i didn't know you can append like that
that's so weird
hard spoke
i originally intended these to change list_x
then it'd just be one line, list_x[len(list_x):] = list_y
cloud fossil
i mean extend
hard spoke
that's slice assignment
the nonintuitive thing is that it can be used in ways that change the list's size
cloud fossil
that's slice assignment
i thought it would raise IndexError or something
hard spoke
I'm technically setting a 0-length slice to an entire list, producing an effect like an extend.
cloud fossil
ye i thought slice assignment gives errors
like index out of range errors
very cool
this is a hack
XD
floral meteor
and this is a press ctrl-c to continue XD
alpine flower
huh actually that gives me a couple real application ideas
like exiting multiple for loops without flags
with suppress(CustomError):
for i in lst:
for j in lst2:
for k in lst3:
...
if value == bad_value: raise CustomError```and that'd just exit the whole block
floral meteor
without having to wrap it in try except, you can just nest it in a context manager
floral meteor
and it's secure: it doesn't create a traceback object, hence it gives you an opportunity to delete decrypted data before it can be caught
alpine flower
+ you don't have to handle the exception
well ig you kind of are but in 1 block compared to 2+a line
floral meteor
for example.
def dingdong():
data=42
1/0
del encrypted_data
try: dingdong()
except ZeroDivisionError as e:
print(e.__traceback__.tb_frame.f_locals['data'])
pretty hacky shit you can do with exception tracebacks tho
I use it from an instance from a class from a module so I can use the globals as context
or modify them >:D
alpine flower
while True:
try:
pass
except(KeyboardInterrupt): # idk if you can tell but i've been doing too much java/non python
pass```ya that's too hacky 5 me :(

why in the __call__?
floral meteor
Trust me, that's useful. cos when you import a namespace, it has a different globals, hence just calling globals() from a function in there will access the module's globals, not the active script
floral meteor
why in the `__call__`?
just to show it being called. that's what __call__ is
like, what if hackyshit wants to see your global annotations to implement some hacky syntax sugar involving colons?
you just do globals()['__annotations__'] and that will call on the module
this accesses where the method is being called from

similar to what I did before
It was really fun
And esoteric 😛
floral meteor
I can make a brainfuck interpreter.
That's a Turing Complete language with its own syntax and language.
easy to make in python
floral meteor
you can't suppress a syntax error in python as it raises before anything that would try to could even compile
tribal moon
And that's where the creativity comes
floral meteor
hence it would have to read string or file, and run from something that passes the SyntaxError test
whatever you make in python has to pass the SyntaxError test to compile. Once you can get it to compile, you can get it to do anything
like
>>> print(four-hundred and twenty)
420.0
>>> print(sixty-nine)
69.0
since that doesn't raise syntaxerror, all sorts of hackery could be used to make that legit (involving assigning instantiated objects to all those names, make them communicate via a core object passed to them all, and have bool, repr and str methods activate them)
also swap sub and add methods of float
@tribal moon
okay, then, here's a challenge for you:
>>> print ( five-hundred and three-thousand and nine-hundred and forty-four-point-seven-seven-nine-three )

is there a guide on how to do these esoteric stuff with python?
snow beacon
Maybe we should compile a compendium of tricks to summarise what's possible in Python.
That way it could be found somewhere search-engine–indexable, rather than tied to this specific corner of the net.
What if future generations need to golf Python?

is there a guide on how to do these esoteric stuff with python?
No, because esoteric python is not a good practice

Everyone choose a favourite piece of Python tomfoolery, the kind of thing you might use to entice someone into the esoteric web. That can be the starting point of a guide.
[0x_for x in input("Hello, world!")] is probably my favourite morsel.
(It evaluates to [15].)
snow beacon
0x_f is a hex literal, 15. The or is parsed as a different word because it doesn't begin with a hex digit, so it's [15 or (x in input("..."))], and since or is short-circuiting, the second half is never executed.
That means no NameError from x.

imma use that instead of one now.
floral meteor
that method of implementing case is awesome, how does that case work?
I originally made it to do this nice compact but limited syntax:
switch: 5
case[4](print,"no printy")
case[5](print,"status green")
otherwise(print,"status red")
but then i realised i could just use them as decorators and do this:
switch: 5
@case[4]
def do(): raise ValueError("This will not raise")
@case[5]
def do():print("status green")
@otherwise
def do():
import sys
sys.stderr.write("status red")
raise ValueError
but then there's the problem of variable assignment.
I could do some pretty hacky shit to read the locals of both environments but writing to them is beyond me.
!e ```py
def i_hate_locals():
a = 4
exec("a+=3",locals(),locals())
print(a)
i_hate_locals()
@floral meteor :white_check_mark: Your eval job has completed with return code 0.
4
you see it can't write to locals
vague cairn
I like the decorators, but how does the switch start it off?
how is switch: 5 not a syntax error?
floral meteor
the
switch: i form only works in the global frame
if you're using it in a function or local frame, you write it as
switch(i)
floral meteor
how is ```switch: 5``` not a syntax error?
!e switch: 5 = 2;print(annotations['switch'])
night quarryBOT
@floral meteor :white_check_mark: Your eval job has completed with return code 0.
5
OOOOOOHHHHHHH!!!!!! nice.
floral meteor
!e however... ```py
a: 3
def i_hate_locals():
a: 9 = 4
exec("a+=3",locals(),locals())
print(a)
print(annotations['a'])
i_hate_locals()
@floral meteor :white_check_mark: Your eval job has completed with return code 0.
001 | 4
002 | 3
if functions worked the way i wanted them to, that would be 7 and 9 not 4 and 3
hence within a function you gotta do ```py
def i_still_hate_locals():
switch, case, otherwise = Switch()
switch(5)
@case[4]
def do(): raise ValueError("this will not raise")
@case[5]
class do:init=lambda s: print("status green")
@cotherwise
def do():
sys.stderr.write("status red")
raise ValueError
Is there any way to force the parser to stop parsing a file from within?
floral meteor
however, unlike other languages, you can mix the suite into the code, rather than isolate it into a block
from cursedutils import Switch
switch: type("Truthy",(int,),{'__eq__':lambda s,o:o and True or False})(1) = Switch()[0]
def do_one_thing(cond):
case,otherwise=Switch()[1:]
@case[cond]
def do(): print("doot")
@otherwise
def do(): print("no doot for you")
def do_another_thing(cond, a:list):
case,otherwise=Switch()[1:]
@case[cond]
def do(): a.append(4)
@otherwise
def do(): a.pop(0)
return a
do_one_thing(1)#doot
do_one_thing(0)#no doot for you
do_another_thing(0,do_another_thing(1,[0,1,2,3]))#[1,2,3,4]
wdym?

earnest wing
Let's say I have a file AB where A is valid python and B is some binary data
I want python3 to parse A but stop reading the file at the start of B
floral meteor
yeah that should work
floral meteor
the chances the binary data doesn't raise an error or does effect the module are negligable
# a file runnings in ze python3
try: import AB
except: print("nope this shit unimportable. or is it?")
__import__('os').system("pip install fuckit")
import fuckit
fuckit('AB')
print(dir(AB)) # suddenly, it works.
:?
floral meteor
try it
earnest wing
I'm not sure what you're trying to say
floral meteor
whatever AB is, fuckit will filter out the non-python
a line raises a syntax error? fuckit.
you could make every second line binary data. fuckit will skip those lines and only import the lines that don't raise an error
earnest wing
That doesn't work in the same file, though
and no deps although I could reimplement fuckit
floral meteor
you can't do shit precompilation lol. it can't have any syntax error to compile in the first place, so nothing in the file will run if there's a wrong unicode character or something
earnest wing
could have said that from the beginning ty
floral meteor
do you know which line the binary data starts?
earnest wing
Okay got it
I'll use the -x command line arg to skip parsing the first line, embed the binary data there

what does `globals().update(__annotations__)` do?
globals() returns a dictionary representing the global namespace.
update is something like this:
class dict:
...
def items(self):
iterable=[]
for element in self:
iterable+=[(element,self[element])]
return iterable
def update(self,d=None,**kwargs):
if d:
for this,that in d.items(): self.__setitem__(this,that)
if kwargs:
for this,that in kwargs.items(): self.__setitem__(this,that)
and __annotations__ searches the global frame for var: annotation
